A Program to Find the Area of a Square
In this example, we are giving a program to find the area of a square. The rule of finding the area of a square is: A = length * length.
Program to find the area of a square:
#include <iostream>#include <cmath>using namespace std;int main() {float l, area;cout << "Enter the value of length of a side: " << endl;cin >> l;area = pow(l,2);cout << "Area of square: " << area;return 0;}
Output:
Enter the value of the length of a side: 3 Area of square: 9.00
