The following program generates an error. Why? #include #include using namespace std; class Arcade { public: Arcade(); Arcade(string name, int r); void Print(); private: string arcName; int rating; }; Arcade:: Arcade() { arcName = "New"; rating = 1; } Arcade:: Arcade(string name, int r) { arcName = name; rating = r; } void Arcade:: Print() { cout << "Name is: " << arcName << endl; cout << "Rating is: " << rating << " stars" << endl; } int main() { Arcade myArc(Games Ablaze, 5); myArc.Print(); }
Answer:
The object creation should be Arcade myArc("Games Ablaze",5);
Explanation:
Required
Why does the program generate an error?
The class definition is correctly defined and implemented;
The methods in the class are also correctly defined and implemented.
The error in the program is from the main method i.e.
int main() {
Arcade myArc('ames Ablaze, 5);
myArc.Print();
}
In the class definition;
Variable name was declared as string and variable rating was declared as integer
This means that, a string variable or value must be passed to name and an integer value or variable to rating.
Having said that:
Arcade myArc(Games Ablaze, 5); passes Games Ablaze as a variable to th function.
Game Ablaze is an incorrect string declaration in C++ because of the space in between Game and Ablaze
Also, no value has been assigned to the variable (assume the variable definition is correct).
This will definitely raise an error.
To correct the error, rewrite the object creation as:
Arcade myArc("Games Ablaze",5); where "Game Ablaze" is passed as string

Can you help me in this question
Answer:
I think the third one (or the one with monkeys).
Explanation:
2+2 does not equal 5, so the if then statement is void because both parts are wrong.
1+1 does not equal 3 even if 2+3 =5, so it is not the second answer.
3+1 does not equal 3, but monkeys do fly and it is an or option, so when one of them is correct in an or, it is correct.
An array A[0..n - 2] contains `n-1` integers from 1 to `n` in increasing order. (Thus one integer in this range is missing.) Design an algorithm in $\Theta(\log n)$ to find the missing integer. Your algorithm should be given in **pseudo code**. For example, the array `A` could be `{1, 2, 3, 4, 6, 7, 8, 9, 10}` in which `5` is missing.

In a paragraph, describe in detail a practical real-world example of where you would implement a singly-linked list and why a singly-linked list is best for this use. Do not list the properties of a singly-linked list....
Rather identify a real-world example or application. If you identify this through research, cite your source.
Answer:
travel
Explanation:
One real world example of a singly-linked list would be travel. Imagine that you want to take a trip to your nearest neighbor state. To do so you would need to take a 2 buses and a train, but you can't just take any or in any order you wish. You first need to take the first bus at your current location, get off at the train station, take that train to the final stop, get off and take the bus to the final destination. Meaning there is a sequence of connected events that you must follow in order to get to your destination and the same opposite sequence of events to get back. This is exactly like a singly-linked list.
Prime numbers can be generated by an algorithm known as the Sieve of Eratosthenes. The algorithm for this procedure is presented here. Write a program called primes.js that implements this algorithm. Have the program find and display all the prime numbers up to n = 150.
Sieve of Eratosthenes Algorithm
To Display All Prime Numbers Between 1 and n
Step 1: We need to start with all the numbers representing the range of numbers that are possible candidate primes. So, create an array of consecutive integers from 2 to n: (2,3,4,..n). I wouldn't hand-code this. I would use a loop to populate the array.
Step 2: At each step we select the smallest number and remove all it's multiples. So we'll start with an outer loop that goes from 2 to n. initially, let p equal 2, the first prime number.
Step 3: In an inner loop we need to iterate over all the numbers that are multiples of p, i.e for 2, that's 2,4,6,8 etc. Each time, setting it's value to false in the original array.
Step 4: Find the first number greater than p in the list that is not marked False. If there was no such number, stop. Otherwise, let p now equal this number( which is the next prime), and repeat from step 3.
When the algorithm terminates, all the numbers in the list that are not marked False are prime
Example: Let us take an example when n = 50. So we need to print all print numbers smaller than or equal to 50. We create list of all numbers from 2 to 50.
2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 42 43 44 45 46 47 48 49 50
Answer:
const MAXNR=150;
let candidates = {};
for(let i=2; i<=MAXNR; i++) {
candidates[i] = true;
}
for(let p=2; p <= MAXNR; p++) {
if (candidates[p]) {
process.stdout.write(`${p} `);
// Now flag all multiples of p as false
i=2;
while(p*i <= MAXNR) {
candidates[p*i] = false;
i++;
}
}
}

Suppose that the first goal in a GP problem is to make 3 X1 + 4 X2 approximately equal to 36. Using the deviational variables d1− and d1+, the following constraint can be used to express this goal.
3 X1 + 4 X2 + d1− − d1+ = 36
If we obtain a solution where X1 = 6 and X2 = 2, what values do the deviational variables assume?
a. d1− = 0, d1+ = 10
b. d1− = 6, d1+ = 0
c. d1− = 5, d1+ = 5
d. d1− = 10, d1+ = 0
Answer:
d. d1− = 10, d1+ = 0
Explanation:
Given
3X1 + 4X2 +d1− − d1+ = 36
X1 = 6
X2 = 2
Required
Possible values of d1- and d1+
We have:
3X1 + 4X2 +d1− − d1+ = 36
Substitute values for X1 and X2
3 *6 + 4 * 2 + d1- - d1+ = 36
18 + 8 + d1- - d1+ = 36
Collect like terms
d1- - d1+ = 36 - 18 - 8
d1- - d1+ = 10
For the above equation to be true, the following inequality must be true
d1- > d1+
Hence,
(d) is correct
Because:
10 > 0

Regarding the role played by the “victim” in deadlock resolution, give an example of such a deadlock in real life and explain your answers to these questions.
a. Describe how you might choose the victim to be removed and the consequences, both positive and negative, of that removal.
b. Describe the fate of the victim and the chances of eventually completing its processing.
c. Describe the actions required, if any, to complete the victim’s tasks.
Answer:
Here the answer is given as follows,
Explanation:
The real-life situation of a deadlock resolution where a role is played by the victim is given as follows:
Example: An example of such a situation are often a one-way lane where the flow of traffic is merely in a method. Thus, on just one occasion, the flow of traffic can enter one direction only. Each entrance/exit gate is often considered a resource. during this case, if two cars are coming from both the entrances and that they are often considered as two tasks, then one among the cars must copy or we will say hand over its resource in order that the opposite car gets the prospect to first cross the lane or we will say the opposite task gets executed.
a) Victim: The steps which describe how a victim is chosen are given as follows :
The task which is terminated so as to interrupt things of deadlock is taken into account because of the victim.
There are often a variety of job pools that will be under a deadlock situation and therefore the victim is usually a low-priority task in order that the performance isn't affected that much and termination of this task doesn't cause any effect on the opposite jobs.
the main positive effect of selecting and terminating a victim is that things of deadlock are resolved and every one of the tasks can execute now.
The negative effect is that the task that's chosen because the victim is terminated and is executed at the previous. This whole process for choosing a victim then terminating it then restarting it again may consume some longer also.
b) An easy deadlock priority is often set. this suggests that the victim’s task or the task is often terminated so as to interrupt the deadlock and other jobs can finish executing. After this, the task which is terminated are often later restarted and every one of the tasks can then execute without a deadlock.
c) When employment gets terminated, the knowledge associated with it's stored. Are often This is often done in order that the work can be restarted again and therefore the information in it's not lost. Since the progress of the victim is stopped. Thus, the sole thanks to complete the victim’s task would be to start out it again. But before restarting the task, this must be considered that the victim’s task doesn't cause any deadlock within the system.
what's the difference between pseudo code and natural language
Answer:
The pseudo-code describes steps in an algorithm or another system in plain language. Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming.
Natural languages consist of phrases, usually declarative phrases, with a sequence of information.
Explanation:
Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming. It usually omits information that is essential to the understanding of the algorithm by the machine, for example, variable declarations and language code.Easily human, but not machines, use the natural languages (like English).Natural languages also are creative. Poetry, metaphor, and other interpretations are permitted. Programming permits certain style differences, but the significance is not flexible.The aim of using pseudo-code is to make it easier for people to comprehensibly than standard programming language code and to describe the key principles of an algorithm efficiently and environmentally independently. It is usually used for documenting software and other algorithms in textbooks and scientific publications.In which type of class methods is it typically necessary to filter bad arguments (either directly or indirectly with the help of validators) in order to protect private data of your class

In this lab, you complete a prewritten C++ program that computes the largest and smallest of three integer values. Instructions Two variables named largest and smallest are declared for you. Use these variables to store the largest and smallest of the three integer values. You must decide what other variables you will need and initialize them if appropriate. Your program should prompt the user to enter 3 integers. Write the rest of the program using assignment statements, if statements, or if else statements as appropriate. There are comments in the code that tell you where you should write your statements. The output statements are written for you. Execute the program by clicking the Run button at the bottom of the screen. Using the input of -50, 53, 78, your output should be: The largest value is 78 The smallest value is -50
Answer:
The program in C++ is as follows
#include <iostream>
using namespace std;
int main(){
int n1, n2, n3, largest, smallest;
cin>>n1>>n2>>n3;
if(n1 >= n2 && n1>=n3){ largest = n1; }
else if(n2 >= n1 && n2>=n3){ largest = n2; }
else{ largest = n3; }
if(n1 <= n2 && n1<=n3){ smallest = n1; }
else if(n2 <= n1 && n2<=n3){ smallest = n2; }
else{ largest = n3; }
cout<<"Smallest: "<<smallest<<endl;
cout<<"Largest: "<<largest<<endl;
return 0;
}
Explanation:
Declare all variables
int n1, n2, n3, largest, smallest;
Get input for the three numbers
cin>>n1>>n2>>n3;
Check if n1 is the largest
if(n1 >= n2 && n1>=n3){ largest = n1; }
Check if n2 is the largest
else if(n2 >= n1 && n2>=n3){ largest = n2; }
Otherwise, n3 is the largest
else{ largest = n3; }
Check if n1 is the smallest
if(n1 <= n2 && n1<=n3){ smallest = n1; }
Check if n2 is the smallest
else if(n2 <= n1 && n2<=n3){ smallest = n2; }
Otherwise, n3 is the smallest
else{ largest = n3; }
Print the smallest
cout<<"Smallest: "<<smallest<<endl;
Print the largest
cout<<"Largest: "<<largest<<endl;
Given 4 floating-point numbers. Use a string formatting expression with conversion specifiers to output their product and their average as integers (rounded), then as floating-point numbers. Output each rounded integer using the following: print('{:.0f}'.format(your_value)) Output each floating-point value with three digits after the decimal point, which can be achieved as follows: print('{:.3f}'.format(your_value))
Answer:
The program is as follows:
prod = 1
isum = 0
for i in range(4):
num = float(input())
prod*=num
isum+=num
avg = isum/4
print('{:.0f}'.format(prod))
print('{:.3f}'.format(avg))
Explanation:
This initializes the product to 1
prod = 1
..... and sum to 0
isum = 0
The following iteration is repeated 4 times
for i in range(4):
Get input for each number
num = float(input())
Calculate the product
prod*=num
Add up the numbers
isum+=num
This calculates the average
avg = isum/4
Print the products
print('{:.0f}'.format(prod))
Print the average
print('{:.3f}'.format(avg))

Alex, a web designer, is assigned the task of creating a mobile device-friendly website for a leading fashion outlet called AllStyles. A desktop version of AllStyles's website already exists. Alex can refer to this desktop version of the website to create the mobile website design The desktop version of the website contains a long list of hyperlinks and this can obstruct the view of the main content when Viewed from a mobile device. Which of the following should Alex use to hide this long list of hypertext links so that it appears only in response to a tap of a major heading in the navigation list?
a. Navigator menus
b. Pulldown menus
c. Pop-up links
d. Header links
Answer: Pulldown menus
Explanation:
Pulldown menus refer to the graphical control element, that is identical to a list box, which enables user to be bake to select one value from a list.
They're regarded as the menu of options that will appear when an item is selected with a mouse. In this case, the item that the user selected will show at the top of the display screen, while the menu appears will show below it.
Therefore, Alex should use the pulldown menus to hide the long list of hypertext links so that it appears only in response to a tap of a major heading in the navigation list.
The input to the function/method consists of two arguments.
a. True
b. False
Answer:
See Explanation
Explanation:
The function is not given. So, I will provide general explanation.
A function is defined as:
return-type function-name(argument-lists)
For instance, an int function that has 1 argument is:
int Myfunc(int num)
num is the argument of the function Myfunc
So, an example of a function with two arguments is:
int Myfunc(int num, string name)
So, examine the function in the complete question; then count the number of arguments to determine if the answer is true or false.
How is an API different from a web application?
Answer:
Web services (web application) are an API type to be accessed via a network connection. While APIs are application interfaces, this means standardized communication between one application and another application.
Explanation:
Web service is used for communication with REST, SOAP, and XML-RPC.While API for all communication styles is used.
The APIs are all web services. Whereas web services are not APIs.The Web application has no lightweight design, needs a SOAP agreement for sending or receiving system information. While the architecture is lightweight, API is useful for gadgets with limited transmission capacities like smartphones.The web application supports the HTTP protocol only. Whereas the API HTTP/s protocol supports: URL Request / Answer Header etc.The web application is not open source, but any customer who contains XML can devour it. While API is open-source and has a .net framework.Write a c++ program to find;

Digital signatures are significantly more secure than other forms of electronic signatures.Determine whether or not the following pairs of predicates are unifiable. If they are, give the most-general unifier and show the result of applying the substitution to each predicate. If they are not unifiable, indicate why. Assume that x, y, and z are variables, while other symbols are either predicates, constants, or functions.
a) P(B,A,B), P(x,y,z)
b) P(x,x), Q(A,A)
c) Older(Father(y),y), Older(Father(x),John).
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B)
e) P(f(x), x, g(x)), P(f(y), A, z)
Answer:
a) P(B,A,B), P(x,y,z)
=> P(B,A,B) , P(B,A,B}
Hence, most general unifier = {x/B , y/A , z/B }.
b. P(x,x), Q(A,A)
No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q.
c. Older(Father(y),y), Older(Father(x),John)
Thus , mgu ={ y/x , x/John }.
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))
=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))
This is not unifiable as x cannot be bound for both A and B.
e) P(f(x), x, g(x)), P(f(y), A, z)
=> P(f(A), A, g(A)), P(f(A), A, g(A))
Thus , mgu = {x/y, z/y , y/A }.
Explanation:
Unification: Any substitution that makes two expressions equal is called a unifier.
a) P(B,A,B), P(x,y,z)
Use { x/B}
=> P(B,A,B) , P(B,y,z)
Now use {y/A}
=> P(B,A,B) , P(B,A,z)
Now, use {z/B}
=> P(B,A,B) , P(B,A,B}
Hence, most general unifier = {x/B , y/A , z/B }
b. P(x,x), Q(A,A)
No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q
c. Older(Father(y),y), Older(Father(x),John)
Use {y/x}
=> Older(Father(x),x), Older(Father(x),John)
Now use { x/John }
=> Older(Father(John), John), Older(Father(John), John)
Thus , mgu ={ y/x , x/John }
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))
Use { y/x }
=> Q(G(x,z),G(z,x)), Q(G(x,x),G(A,B))
Use {z/x}
=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))
This is not unifiable as x cannot be bound for both A and B
e) P(f(x), x, g(x)), P(f(y), A, z)
Use {x/y}
=> P(f(y), y, g(y)), P(f(y), A, z)
Now use {z/g(y)}
P(f(y), y, g(y)), P(f(y), A, g(y))
Now use {y/A}
=> P(f(A), A, g(A)), P(f(A), A, g(A))
Thus , mgu = {x/y, z/y , y/A }.

The system of water spray pipes was too low to helpc. The system of water spray pipes broked. The system of water spray pipes did not have sufficient water supply
Answer:
d. The system of water spray pipes did not have sufficient water supply
Explanation:
The Union Carbide India Ltd. was chemical factory situated at Bhopal that produces various pesticides, batteries, plastics, welding equipment, etc. The plant in Bhopal produces pesticides. In the year 1984, on the night of 2nd December, a devastating disaster occurred on the Bhopal plant which killed millions of people due to the leakage of the poisonous, methyl isocyanate. This disaster is known as Bhopal Gas tragedy.
Soon after the gas pipe exploded, the fire brigade started spraying water into the air to [tex]\text{knock down}[/tex] the cloud of the gases in the air but there was not sufficient amount of water in the water sprays and so it was not effective.
Thus the correct answer is option (d).

for (int i = for_reverse.size() - 1; i > 0; i--){

return 0;
}
Explanation:
This declares sentence and word as strings; word is then initialized to an empty string
string sentence,word="";
This gets input for sentence
getline (cin, sentence);
This creates a string vector to reverse the input sentence
vector<string> for_reverse;
This iterates through the sentence
for (int i = 0; i < sentence.length(); i++){
This pushes each word of the sentence to the vector when space is encountered
if (sentence[i] == ' ') {
for_reverse.push_back(word);
Initialize word to empty string
word = ""; }
If the encountered character is not a blank space, the character is added to the current word
else{ word += sentence[i];} }
This pushes the last word to the vector
for_reverse.push_back(word);
This initializes sentence to an empty string
sentence="";
This iterates through the vector
for (int i = for_reverse.size() - 1; i > 0; i--){
This generates the reversed sentence
sentence+=for_reverse[i]+" ";}
This adds the first word to the end of the sentence
sentence+=for_reverse[0];
Print the sentence
cout<<sentence<<endl;
Explain in details:
(i) Deadlock
(ii) File manager
(iii) Process
(iv) Multiprogramming
(v) Software Classification
(vi) Virtual memory
Answer and Explanation:
Deadlock occurs when two operating systems on the same computer are hindering each other's execution, getting blocked, waiting for each one to run first. This can happen when a preemption has not occurred, when a mutual exclusion has occurred, or when one of the systems causes the other to not execute.
File manager is software that allows a computer user to create directories and organize files inside and outside of them.
Process is the term used to determine the functioning of computer software. When a software is started, it uses its own programming code to perform a specific activity.
Multiprogramming is the term used for the moment when an operating system allows the user to run more than one software at the same time. For this to happen, the computer needs to have a high processing capacity, to handle the effort of running several software simultaneously.
Software Classification is the process that determines the composition and different aspects that make up a software. In this way, it is possible to understand the usefulness and programming of this software.
Virtual memory is the use of secondary memory for caching. This allows the user to share files more securely and quickly, in addition to alleviating the problems that limited memory presents.
