C Program to find Perimeter of a Rhombus

Write a C Program to find the perimeter of a Rhombus with an example. The math formula to find the Rhombus perimeter is 4 * sides. This C example allows entering rhombus sides and returns the perimeter.

#include <stdio.h>

int main()
{
    float rmside, rmperimeter;
    
    printf("Enter the Rhombus Side = ");
    scanf("%f",&rmside);

    rmperimeter = 4 * rmside;

    printf("The Perimeter of the Rhombus = %.3f\n", rmperimeter);
    
    return 0;
}

In this C Program, we created a function to calculate and return the Rhombus perimeter.

#include <stdio.h>

float rhombusPerimeter(float side)
{
    return 4 * side;
}

int main()
{
    float rmside, rmperimeter;
    
    printf("Enter the Rhombus Side = ");
    scanf("%f",&rmside);

    rmperimeter = rhombusPerimeter(rmside);

    printf("The Perimeter of a Rhombus = %.3f\n", rmperimeter);
    
    return 0;
}

Enter the Rhombus Side = 12
The Perimeter of a Rhombus = 48.000

C Program to Calculate Perimeter of a Rhombus using Pointers.

#include <stdio.h>

void rhombusPerimeter(float *rmside, float *rmperimeter)
{
    *rmperimeter = 4 * (*rmside);
}

int main()
{
    float rmside, rmperimeter;
    
    printf("Enter the Rhombus Side = ");
    scanf("%f",&rmside);

    rhombusPerimeter(&rmside, &rmperimeter);

    printf("The Perimeter of a Rhombus = %.3f\n", rmperimeter); 
    
    return 0;
}

Enter the Rhombus Side = 32
The Perimeter of a Rhombus = 128.000
