c学的不是很好，看不出错哪了，请帮忙看看
//题目：一个数如果恰好等于它的因子之和，这个数就称为“完数”。例如6=1＋2＋3.编程找出1000以内的所有完数。#include<stdio.h>
void main()
{
long int s,t=1,i=0;
long int b[1000],a;
if(s=1;s<=1000;s++)
{
if(a=2;a<=s;a++)
{
if(s%a==0)
{
t=t+a;
s=s/a;
}
}
if(s==t)
{
b[i]=s;
i++;
}
}
printf("the wanshu is:\n");
for(long int j=0;j<=i;j++)
printf("%ld ",b[j]);
