Write a program to find Area of a Square in C++

Area of a square = l^2
    l = length of side

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13

#include <iostream.h> #include <conio.h> int main() { int l, l2; cout << " Area of a square = l^2\n"; cout << " Enter the value of length?\n"; cin >> l; l2 = l * l; cout << "\t" << "Area of a square = " << l2 << " m^2 " << " \n"; getch(); return 0; } // end main

Output:

 Area of a square = l^2
 Enter the value of length?
7
 Area of a square = 49 m^2
