# C Program to Find Perimeter of Rhombus

In this tutorial, i am going to show you how to find or calculate perimeter of rhombus with the help of standard formula, function and pointer in c programs.

## All C Programs and Algorithm to Find Perimeter of Rhombus

• Algorithm to Find Perimeter of Rhombus
• C Program to Find Perimeter of Rhombus using Standard Formula
• C Program to Find Perimeter of Rhombus using Function
• C Program to Find Perimeter of Rhombus using Pointer

### Algorithm to Find Area of Perimeter

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

1. Take input two side of perimeter of rhombus. Store it in two different variables.
2. Calculate perimeter of rhombus using `area=(d1*d2)/2;`
3. Finally, print the value of Perimeter of rhombus.

### C Program to Find Perimeter of Rhombus using Standard Formula

```#include<stdio.h>
int main()
{
float side,perimeter;
printf("enter side of rhombus: ");
scanf("%f",&side);

perimeter=4*side;
printf("Perimeter Of Rhombus: %f\n",perimeter);
return 0;
}```

The result of the above c program; as follows:

```enter side of rhombus: 5
Perimeter Of Rhombus: 20.000000```

### C Program to Find Perimeter of Rhombus using Function

```#include<stdio.h>
float perimeter(float s)
{
return (4*s);
}

int main()
{
float s,p;

printf("enter side of rhombus: ");
scanf("%f",&s);

p=perimeter(s);
printf("Perimeter Of Rhombus: %f\n",p);
return 0;
}```

The result of the above c program; as follows:

```enter side of rhombus: 8
Perimeter Of Rhombus: 32.000000```

### C Program to Find Perimeter of Rhombus using Pointer

```#include<stdio.h>
void perimeter(float *s,float *p)
{
*p=((4)*(*s));
}

int main()
{

float s,p;

printf("enter side of rhombus: ");
scanf("%f",&s);

perimeter(&s,&p);
printf("Perimeter Of Rhombus: %f\n",p);
return 0;
}```

The result of the above c program; as follows:

```enter side of rhombus: 50
Perimeter Of Rhombus: 200.000000```
