Program to find the area of a triangle using Heron's formula in C.

#include <stdio.h>
#include <math.h>

void main(){
	
	float area , a , b , c ,p ;
	
	printf("enter sides : ");
	
	scanf("%f %f %f" , &a ,&b , &c);
	
	p = (a + b + c)/2 ;
	
	area = sqrt(p*(p-a)*(p-b)*(p-c));
	
	printf ("area : %f\n" , area);
	
}
