C Program to Calculate Area of Square

In this post we are going to write a C program to calculate the “Area of square”.

Formula for calculating “Area of square” is,

Area of a square = side times side (Area = side * side).

Using this formula let’s write the C Program:

#include <stdio.h>

int main(){
	
	//set the float variables
	float side, area;
	
	//get the input value
	printf("Enter side of square: ");
	scanf("%f", &side);
	
	//calculate the area
	area = side * side;
	
	//print the output with 2 decimals
	printf("Area of square is: %.2f", area);

	return (0);
}

Output of the above program:

Enter side of square: 2.5
Area of square is: 6.25
