How to find out the area of the rhombus in C programming language?

That's really good to convert mathematics formulas in the C programming language. I always said the C language is the base of every programming language. You can find out the area of the rhombus using the C language. First of all, understand the mathematics formula for the area of the rhombus. 

Area of the rhombus - A = pq/2 

A = Area of the rhombus.

p= Diagonal of the rhombus.

q= Diagonal of the rhombus.

You should understand the C concepts. There are three variables in the area of the rhombus A, p, q.

We can convert into C programming like - a=p*q/2   

Where - 

a = Area of the rhombus in C language. 

p = Diagonal of the rhombus in C language. 

q = Diagonal of the rhombus in C language. 

Let's create a program to find out the area of the rhombus in the C programming language.

#include <stdio.h>
#include<math.h> 
int main()
{
    float a;
    float p=2.0; 
    float q=4.5;
    a=p*q/2; 
    printf("Area of the rhombus= %.2f\n", a);
    return 0;
}

Compile and execute the above C program. You will get the area of the rhombus as output. 

Area of the rhombus= 4.50   

The area of the rhombus is depended on the diagonals. We can specify these diagonals like - d₁ and d₂. The d₁ represents the diagonal one and the d₂ represents the diagonal two of the rhombus. We can find out the area or any diagonal using the C language. 

Let's find out the area of the rhombus using C programming language.

To find out the area in C language, you need to declare three variables like - float a, float d1 and float d2.  You can define the value of the variables.

#include <stdio.h>
#include<math.h> 
void main()
{

    float a,d1,d2; 
    d1=6.0; 
    d2=6.0; 
    a=d1*d2/2; 
       printf("Area of the rhombus= %.f\n", a);
}

Output - 

Area of the rhombus= 18
