int cube(int x); //The prototype.

void main()
{
clrscr();
int a;
cout << “Enter an integer : “;
cin>>a;
cout << “The cube of ” << a << ” is : ” << cube(a) << endl; //Call the function cube(a).

//Defining the function.
int cube(int x)

}

This program takes in an integer a as a screen input from the user.
It then determines the integer’s cube and outputs it using the ‘cout’ command.
