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;
