Write a C Program to possibility of triangular where all sides are user given

#include <stdio.h>
#include <conio.h>
void main()
{
 int a,b,c,max=0,sum=0;
 clrscr();
 printf("Enter Value for Three Sides: ");
 scanf("%d %d %d",&a,&b,&c);
 if(a>b)
 {
  if(a>c)
  {
   max=a;
  }
  else
  {
   max=c;
  }
 }
 else
 {
  if(b>c)
  {
   max=b;
  }
  else
  {
   max=c;
  }
 }
 sum=a+b+c-max;
 if(sum>max)
 {
  printf("\nTriangular is possible");
 }
 else
 {
  printf("\nTriangular is not possible");
 }
 getch();
}
