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.
