Using the knowledge in computational language in C++ it is possible to write a code that complete program that declares an integer variable, reads a value from the keyboard in that variable.
Writting the code:
#include<iostream>
using namespace std;
int main()
{
//declare an integer variable
int n;
//read a value from the keyboard
//cout << "Enter an integer: ";
cin >> n;
//display the square of the variables value
//cout << "The square of the number entered is: ";
cout << n * n;
return 0;
}
