C program to find prime factors of the given number

#include<stdio.h>

void main()
 {
  int n,m,sum=0,a;
  int i;
  int count;
  int j;
  printf("Enter a no");
  scanf("%d",&n);
  m=n;
  for(i=2;i<=n/2;i++)
   {
    a=0;
    if(n%i==0)
     {
      count=0;
      for(j=2;j<=i/2;j++)
       {
if(i%j==0)
{
 count++;
 break;
}
}
if(count==0)
{
 printf("Prime factor is %d \n",i);
}
}
      }
}

output
Enter a no 50
Prime factor is 2
Prime factor is 5
