The for loop statements in the program are:

To use the enhanced for loop, we make use of the for each statement.

This syntax of the enhanced for loop is:

for(int elem : elems)

Where elem is an integer variable and elems is an array or arrayList

So, we have the following modifications:

Hence, the modified program in Java is:

Random rd = new Random();

int[] arr = new int[nrElements];

int i = 0;

for (int num : arr){

arr[i] = rd.nextInt(1000);

i++;

}

return arr;

}

static void printArray(int[] arr) {

for (int num : arr) {

The Python program to calculate the average of all even integers between 1 and 10000 is given below.

We have,

The Python program to calculate the average of all even integers between 1 and 10000:

def main():

   even_sum = 0

   count = 0

   for num in range(2, 10001, 2):  # Starting from 2 and incrementing by 2 (only even numbers)

       even_sum += num

       count += 1

   if count > 0:

       average = even_sum / count

       print("Average of even integers between 1 and 10000:", average)

   else:

       print("No even integers between 1 and 10000.")

if __name__ == "__main__":

   main()

In this program, we define a function main() that runs the main logic.

We initialize even_sum to store the sum of even numbers and count to keep track of how many even numbers we encounter.

The for loop iterates through even numbers between 2 and 10000 (using the range() function with a step of 2).

Inside the loop, it adds each even number to even_sum and increments the count.

Thus,

The Python program to calculate the average of all even integers between 1 and 10000 is given above.

The use of the inheritance to have a structure inherit attributes and methods of classes above it.

One of the key milestones in the period in which the object-relational model was created was the creation of a data
model that closely represented the real world. In this approach, objects were created in which both data and its
relationships were all contained in one place. These data models were becoming a norm to be stored on the web. They
also incorporated support for star schemas within data warehouses. Objects that had similar characteristics were
grouped into classes, where they had a shared structure of attributes and behaviors.

One of the milestones during this period was the use of Unified Modeling Language to represent the data models. The correct option is C.

Using object-oriented programming languages, object-relational mapping is a programming technique used in computer science to convert data between type systems. As a result, the programming language becomes a "virtual object database" that may be used.

One of the significant achievements throughout the development of the object relational model was the development of a data model that accurately reflected the real world.

Using this method, objects were constructed that contained all of the data and the relationships between it. The storage of these data models online was starting to become standard.

Additionally, they included support for star schemas in data warehouses. Classes would be composed of comparable structures with similar shared characteristics and actions.

Thus, the correct option is C.

IDS or Intrusion detection system is very powerful but clever attack can make it reckless

#1

It generally denotes to sending dummy intruders in multiple amount the IDS gets confused and attacker can go

#2

Using codewords or doing encoding and decoding(Obfuscating)

#3

Using shell codes

The three ways for the attacker to avoid raising alarms from intrusion detection systems are

Explanation:

Session splicing and fragmentation - involve breaking, slicing, and splitting packets into multiple pieces such that no single packet causes the IDS to trigger an alert.

Invalid packets - Sending invalid TCP packets is another way of evading an IDS.

Polymorphic shellcodes -Most IDS systems have a standard default set of intrusion signatures. Attackers can modify the attack payload so that it doesn’t match the default IDS signature and gets through it.
