Algorithm to Find Perimeter of a Square

Just follow the below given algorithm to write a program to find the perimeter of a square; as follows:

1. Take input side of square. Store it in variable.
2. Calculate perimeter of square using perimeter=4*side;;
3. Finally, print the value of perimeter of square.

C Program to Find Perimeter of a Square using Standard Formula

#include<stdio.h>
int main()
{
	float side,perimeter;
	printf("enter side of square: ");
	scanf("%f",&side);
	
 
	perimeter=4*side;
	printf("Perimeter Of Square: %f\n",perimeter);
	return 0;
}

The result of the above c program; as follows:

enter side of square: 5
Perimeter Of Square: 20.000000

C Program to Find Perimeter of a Square using Function

 #include<stdio.h>
float perimeter(float s)
{
	return (4*s);
}
 
int main()
{
	float s,p;
	
	printf("enter side of square: ");
	scanf("%f",&s);
	
	p=perimeter(s);
	printf("Perimeter Of Square: %f\n",p);
	return 0;
}

The result of the above c program; as follows:

enter side of square: 10
Perimeter Of Square: 40.000000

C Program to Find Perimeter of a Square using Pointer

#include<stdio.h>
void perimeter(float *s,float *p)
{
	*p=((4)*(*s));
}
 
int main()
{
    
	float s,p;
	
	printf("enter side of square: ");
	scanf("%f",&s);	
 
	perimeter(&s,&p);
	printf("Perimeter of a Square: %f\n",p);
	return 0;
}

The result of the above c program; as follows:

enter side of square: 9
Perimeter of a Square: 36.000000
