Prime numbers between "1 to n" in C

Write a program (WAP) in C to print Prime numbers between "1 to n".

#include<stdio.h>
int main()
{
    int num,i,count,n;
    printf("Enter the range :\n ");
    scanf("%d",&n);

    printf("Prime numbers between 1 to %d are :\n ",n);
    for(num = 1;num<=n;num++)
    {
         count = 0;
         for(i=2;i<=num/2;i++)
         {
             if(num%i==0)
             {
                 count++;
                 break;
             }
         }
         if(count==0 && num!= 1)
             printf("%d ",num);
    }
   return 0;
}
