How to calculate area of square in c++. I have used Dev-C++ IDE for debugging purpose. But you can use any C programming language compiler as per your compiler availability.
C++ Program to Calculate Area of Square
#include<iostream>
#define PI 3.141
using namespace std;
int main()
{
int side, area;
cout << "Enter the Length of Side : ";
cin >> side;
// Formula to calculate area of square
area = side * side;
cout << "Area of Square : "<< area;
return 0;
}Result
