This C program calculates Area of a Square based on the side of Square entered by the user.
A square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or right angles).
Code:
#include<stdio.h>
int main()
{
int side;
printf("\nPlease Enter the Length of Side : ");
scanf("%d", &side);
printf("\nArea of Square : %d", side * side);
return (0);
}
