五一作业

1.  一个数如果恰好等于它的因子之和,这个数被成为”完数”,例如:6=1+2+3.请编程找出1000以内的完数

#include <stdio.h>

int main()
{
        int m,n ,k;

        for (m = 2; m < 1000; m++)
        {
                k = 1;
                for(n = 2;n < m;n++)
                {
                        if(m % n == 0)
                        k += n;
                }
                if(k == m)
                printf("%d\n",m);
        }

        return 0;
}
