How To Write Code For Finding Area Of Triangle In 'C' Language ?

MOST EASY AND UNDERSTANDABLE WAY ,,,[ बिलकुल  आसान  तरीका  ]

CODING IN VERY EASY WAY (text me on fb )

LET  SEE  "C"  ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓ ⇓

#include<stdio.h>

void main()
{
   clrscr();
   float a,b,c,s,area;
   printf("enter the sides of the triangle");
   scanf("%f%f%f",&a,&b,&c);

   if((a+b>c)&&(a+c>b))
 {
   s=(a+b+c)/2;
   area=sqrt(s*(s-a)*(s-b)*(s-c));
   printf("area of the triangle for given sides=%f",area);
 }
   else
  {
   printf("triangle is not valid");
  }
  getch();
}
