c-program to calculate the area of triangle by using pointer | c-programming

 If the length of the sides of a triangle are denoted by a,b,c and  then what is the area of the triangle by using pointer ?

In  this program , we have to taking  three input i,e sides of the triangles form the user and calculate the area of the triangle .

#include<stdio.h>
#include<conio.h>
void main()
{
         float s=0,a,b,c,area=0;
         float *x,*y,*z,*sum,*area1;
         printf("enter the three number:-");
         scanf("%f %f %f",&a,&b,&c);
         x=&a,y=&b,z=&c,sum=&s,area1=&area;
         s=(a+b+c)/2;
         printf("\n the area of the triangle are follow");
         area=sqrt(s*(s-a)*(s-b)*(s-c));
         printf("\n the solution is %.2f",*area1);
         getch();
}

output :-
