# C Program to Find Area of Rhombus

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

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

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

### Algorithm to Find Area of Rhombus

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

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

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

```#include<stdio.h>
int main()
{
float d1,d2,area;

printf("enter diagonal1 of rhombus: ");
scanf("%f",&d1);

printf("enter diagonal1 of rhombus: ");
scanf("%f",&d2);

area=(d1*d2)/2;
printf("Area of Rhombus: %f\n",area);
return 0;
}```

The result of the above c program; as follows:

```enter diagonal1 of rhombus: 5
enter diagonal1 of rhombus: 6
Area of Rhombus: 15.000000
```

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

```#include<stdio.h>
float area(float d1,float d2)
{
return (d1*d2)/2;
}

int main()
{

float d1,d2,a;

printf("enter diagonal1 of rhombus: ");
scanf("%f",&d1);

printf("enter diagonal2 of rhombus: ");
scanf("%f",&d2);

a=area(d1,d2);
printf("Area of Rhombus: %f\n",a);
return 0;
}```

The result of the above c program; as follows:

```enter diagonal1 of rhombus: 10
enter diagonal2 of rhombus: 20
Area of Rhombus: 100.000000```

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

```#include<stdio.h>
void area(float *d1,float *d2,float *area)
{
*area=((*d1)*(*d2))/2;
}

int main()
{

float d1,d2,a;

printf("enter diagonal1 of rhombus: ");
scanf("%f",&d1);

printf("enter diagonal2 of rhombus: ");
scanf("%f",&d2);

area(&d1,&d2,&a);
printf("Area of Rhombus: %f\n",a);
return 0;
}```

The result of the above c program; as follows:

```enter diagonal1 of rhombus: 6
enter diagonal2 of rhombus: 7
Area of Rhombus: 21.000000```
