Implement a class named Rectangle. The class should contain:
1. Two data attributes of type float named width and height that specify the width and the height of the rectangle.
2. A constructor that creates a rectangle with the specified width and height. If no argument is provided, it should use 1.0 for both values. If any input value is negative, the function should raise an exception.
3. Functions get_width and get_height that return the corresponding value
4. The set_width and set_height function that update the values if and only if the input is positive; otherwise do nothing
5. Functions get_area and get_perimeter that return the area and the perimeter of this rectangle respectively.
6. A function rotate that swaps the height and width of a rectangle object.
7. A class variable count that keeps track of the number of rectangles created so far.
8. A class method get_count that returns the above value.
9. An equality operator that returns True if and only if the two rectangles are of the same shape.
10. A __str__ function that returns the information of this rectangle in some readable format.

Answer:

Explanation:

The following code is written in Python and creates a Rectangle class that performs all the necessary functions mentioned in the question...

from itertools import count

class Rectangle():

   _ids = count(0)

   width = 1.0

   height = 1.0

   def __init__(self, width, height):

       if (width < 0) or (height < 0):

           raise Exception("Sorry, no numbers below zero")

       else:

           self.id = next(self._ids)

           self.width = width

           self.height = height

   def get_width(self):

       return self.width

   def get_height(self):

       return self.height

   def set_width(self, width):

       if width > 0:

           self.width = width

   def set_height(self, height):

       if height > 0:

           self.height = height

   def get_area(self):

       return (self.height * self.width)

   def get_perimeter(self):

       return ((self.height * 2) + (self.width * 2))

   def rotate(self):

       temp = self.height

       self.height = self.width

       self.width = temp

   def get_count(self):

       return self._ids

   def equality(self, rectangle1, rectangle2):

       if rectangle1 == rectangle2:

           return True

       else:

           return False

   def __str__(self):

       return 'Rectangle Object with Height: ' + str(self.height) + ' and Width: ' + str(self.width)

A slide titled Alexander Graham Bell. There are 6 bulleted entries on the slide, and there is a lot of text on the slide. There is very little space around the text to the edges of the slide. There is no image on the slide and the text is shaded white on a blue background.
This slide has several design problems, according to the design principles that were just reviewed. What are the problems? Check all that apply.

The slide contains too much text.
The slide does not have an image or visual aid.
The text is too small.
The background makes it hard to read the text.
The slide does not have enough empty space.

The IBM system/370 architecture uses a two-level memory structure and refers to the two levels as segments and pages, although the segmentation approach lacks many of the features described in Chapter 8. For the basic 370 architecture, the page size may be either 2 KB or 4 KB, and the segment size is fixed at either 64 KB or 1 MB. For the 370/XA and 370/ESA architectures, the page size is 4 KB and the segment size is 1 MB. What advantages of segmentation does this scheme lack

Write a full class definition for a class named GasTank , and containing the following members:
A data member named amount of type double.
A constructor that no parameters. The constructor initializes the data member amount to 0.
A function named addGas that accepts a parameter of type double . The value of the amount instance variable is increased by the value of the parameter.
A function named useGas that accepts a parameter of type double . The value of the amount data member is decreased by the value of the parameter. However, if the value of amount is decreased below 0 , amount is set to 0 .
A function named isEmpty that accepts no parameters and returns a boolean value. isEmpty returns a boolean value: true if the value of amount is less than 0.1 , and false otherwise.
A function named getGasLevel that accepts no parameters. getGasLevel returns the value of the amount data member.
class GasTank
{
private:
double amount;
public:
GasTank();
void addGas(double);
void useGas(double);
bool isEmpty();
double getGasLevel();
};
GasTank::GasTank(){amount = 0;}
void GasTank::addGas(double a){amount += a;}
void GasTank::useGas(double a){amount -= a; if (amount < 0) amount = 0; }
bool GasTank::isEmpty(){if(amount < .1) return true; else return false;}
double GasTank::getGasLevel() {return amount;}

The information in DNA Is coded in chemical bases adenosine (A) guanine (G) cytosine (C), and thymine (T) We can represent a DNA strand by stringing together the letters representing the appropriate strand. Imagine we are given a list of DNA strands which have arbitrary lengths. Write a single function strand_counter() which takes a list of DNA strands, counts the lengths of each of the words in the list and then calculates and returns the integer maximum_length integer minimum_length, and float average_length
Then write a program which takes in a user-chosen number of strands of arbitrary length as an input and prints out the calculated information
Example input
5
AT
ATCGTCOGGT
TCGCT
TCGATTCCT
TTCATCG
Example output
The longest strand has length 10.
The shortest strand has length 2.
The average length of the strands is 6.6.

suppose as a head software engineer you assign the job of creating a class to a subordinate. You want to specify thirty-eight different methods in which you are willing to detail the parameters each is to receive as well as what each returns. You, however, do not have the time to create the details of each method and wish to assign that work to the subordinate. What would be your best approach to ensure that the subordinate finishes the assigned job.
