Squaring any number in mathematics is pretty simple and in C++ it is similar. We can calculate the square of any number by multiplying it by itself. And that's it, that is all for today.


How to calculate the square of any number in c++?


Approach → 

Define two int in the program. First int will store the number and the second will store the square of the number.

#include <iostream>
using namespace std;

int main()
     int num,sqr;
     cout << "For getting the square enter the number: ";
     cin >> num;
     sqr = num*num;
     cout << "\nSquare of the number you entered is: " << sqr << endl;
     return 0;


I know it is a very small and very easy article but it is what it is.
