C program to find the perimeter of a square; Through this tutorial, we will learn how to find or calculate perimeter of a square using standard formula, function, and pointer in c programs.
Programs and Algorithm to Find Perimeter of a Square
Let’s use the following algorithm and program to find or calculate perimeter of a square using standard formula, function, and pointer in c:
- Algorithm to Find Perimeter of a Square
- C Program to Find Area Of SemiCircle using Standard Formula
- C Program to Find Area Of SemiCircle using Function
- C Program to Find Area Of SemiCircle using Pointer
Algorithm to Find Perimeter of a Square
Use the following algorithm to write a program to find the perimeter of a square; as follows:
- Take input side of square. Store it in variable.
- Calculate perimeter of square using perimeter=4*side;;
- 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 output 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 output 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 output of the above c program; as follows:
enter side of square: 9 Perimeter of a Square: 36.000000
