C Program to Calculate Area of Any Triangle using Heron's Formula

Write a C program to find the area of a triangle using Heron's Formula.

Program:-

#include <stdio.h>

#include <math.h>

#include <conio.h>

 

int main()

{

    float a, b, c, s, area;

    printf("Enter the length of three sides of triangle\n");

    scanf("%f %f %f", &a, &b, &c);

    s = (a + b + c)/2;

    area = sqrt(s*(s-a)*(s-b)*(s-c));

    printf("Area of triangle : %f", area);

     

    getch();

    return 0;

}

Output :-

Input:

Enter the three sides of the Triangle
a=?

b=?

c=?

Output:-
