Program to Fill and Display an Array with Even Numbers

Here is a program in C++ that fills an integer array of 20 elements with even numbers from 2 to 40 and then displays the array on the screen:

#include

int main() {
    int arr[20];
    int num = 2;

// Fill the array with even numbers
    for (int i = 0; i < 20; i++) {
        arr[i] = num;
        num += 2;
    }

// Display the array
    for (int i = 0; i < 20; i++) {
        std::cout << arr[i] << " ";
    }

return 0;
}

This program declares an integer array `arr` with a size of 20. It also initializes a variable `num` with the value 2. Then, using a `for` loop, it fills the array with even numbers starting from 2 and incrementing by 2 in each iteration. Finally, another `for` loop is used to display the elements of the array on the screen.

When you run this program, it will output the following numbers: 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40.

Please note that this program is written in C++. If you need the program in a different programming language, please let me know.
