Write a program that finds if a given number is a prime number

#include<stdio.h>
void main()
{
   int n,i,count=0;
   scanf("%d",&n);
   for(i=2;i<=n/2;i++)
   {
       if (n%i==0)
       {
           count=1;
           break;
           
       }
   }
   if(count==0)
   {
       printf("prime");
   }
   else 
   {
       printf("non prime");
   }
}
