Program to Calculate the Area of a Triangle

Program to Calculate the Area of a Triangle

This C Program calculates the area of a triangle given it's three sides. The formula or algorithm used is: Area = sqrt(s(s - a)(s - b)(s - c)), where s = (a + b + c) / 2 or perimeter / 2. and a, b & c are the sides of triangle.


    #include <stdio.h>

    #include <math.h>
     

    void main()

    {

        int s, a, b, c, area;
     

        printf("Enter the values of a, b and c \n");

        scanf("%d %d %d", &a, &b, &c);

        /* compute s */

        s = (a + b + c) / 2;

        area = sqrt(s * (s - a) * (s - b) * (s - c));

        printf("Area of a triangle = %d \n", area);

    }
