    your logic is correct but you forget to reinitialize sum=0
    here is the correct code..
    Code:
    main()
    {
    int i,j,sum=0;
    for(i=1;i<=1000;i++)
    {
    for(j=1;j<i;j++)
    {
    if(i%j==0)
    sum=sum+j;
    }
    if(sum==i)
    printf("%d",i);
    sum=0; // insert this line in your code...
    }
    getch();
    }
