C program for area of a triangle

Formula of area of any triangle:

Area = √(s*(s-a)*(s-b)*(s-c))

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

C code:

#include<stdio.h>

#include<math.h>

int main(){

   

    float a,b,c;

    float s,area;

   

    printf("Enter size of each sides of triangle");

    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 is: %.3f",area);

   

    return 0;

}

Sample output:

Enter size of each sides of the triangle: 2 4 5

Area of triangle is: 3.800
