If a natural number N equals it all of the different real factors (namely a few of N and 1, but does not include N) the sum of the S, says the number for the "perfect number", such as 6=1 + 2 + 3 p=1 + 2 + 4 + 7 + 14, so 6 and 28 are perfect, obviously, 6 is 1 (minimal) perfect Numbers,

# include & lt; Stdio. H>
Int main ()
{
Int n, k, s=1;
For (n=6; n<=500; N++)
{
For (k=2; k<=n/2; K++)
{
If (n % k==0)
{
S=s + k;
}
If (n=s)
{
Printf (" perfect number is % d \ n ", n);
}
}
}
return 0;
}
Please the great god given the perfect number are correct code, thank you.
