C Programming

Calculating the AREA of a triangle using equation and if else:

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

float a,b,c,area,s;

clrscr();

printf("\n Enter a:");

scanf("%f",&a);

printf("\n Enter b:");

scanf("%f",&b);

printf("\n Enter c:");

scanf("%f",&c);

if((a+b>c)&(b+c>a)&(c+a>b))

{

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

area=sqrt(s*(s-a)*(s-b)*(s-a));

printf("\n the value of s is=%f",s);

printf("\n the value of area=%f",area);}

else

printf("Not possible");

getch();

}
