#include<stdio.h>
 main()
{
 
    int m,n,sum;

   
    for(m=1;m<=1000;m++)
   
   
        
            
    {
          for(n=1;n<=m/2;n++)
            
        
        {
            if(m%n==0)
                 
             sum=sum+n;
   
               
           
        }   
        if(sum==m)

        {      
         printf(" %d its factory  are : ",m);
           
         
            for(n=1;n<=m/2;n++)

            {

                if (m%n==0)
            
                   printf("%d,",n);   
            }
     
        
         printf("\n");
        }
   
   
   
    }   
    为什么什么也数不出，问题在哪啊？我才学c语言
