C program to find perimeter of a rectangle



C program to find perimeter of a rectangle

Write a C program to input length and width of a rectangle and calculate perimeter of the rectangle. How to find perimeter of a rectangle in C programming.

    Input length and width of the rectangle using scanf() function. Store it in two variables say length and width.
    Calculate perimeter using formula for perimeter of rectangle perimeter = 2 * (length + width).
    Print the value of perimeter.

#include <stdio.h>

int main()
{
    float length, width, perimeter;

    /*
     * Input length and width of rectangle from user
     */
    printf("Enter length of the rectangle: ");
    scanf("%f", &length);
    printf("Enter width of the rectangle: ");
    scanf("%f", &width);

    /* Calculate perimeter of rectangle */
    perimeter = 2 * (length + width);

    /* Print perimeter of rectangle */
    printf("Perimeter of rectangle = %f units ", perimeter);

    return 0;
}
