Create an application named numbersdemo whose main() method holds two integer variables. assign values to the variables. in turn, pass each value to methods named and

The solution code is written in C++.

int main() {    int a = 5;    int b = 4;    displayTwiceTheNumber(a);    displayTwiceTheNumber(b);    displayNumberPlusFive(a);    displayNumberPlusFive(b);    displayNumberSquared(a);    displayNumberSquared(b);    return 0; } void displayTwiceTheNumber(int num){    cout << num * 2; } void displayNumberPlusFive(int num){    cout << num + 5; } void displayNumberSquared(int num){    cout << num * num; }

Explanation:

Firstly, create two integer variables, a and b and two sample values are assigned to the two variables, respectively (Line 3-4). Next, we pass the value of each variable a and b to the methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared() (Line 6- 13).
