Re: printing of perfect numbers

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();

}
