编程求助，快！快！快！

#include "stdio.h"
void main()
{
int i,sum=0;
for(i=1;i<=100;i++)
{if(i%6==0)
sum+=i;}
printf("%d ",sum);
}
结果是816.我运行过.

include <iostream.h>
void main()
{
int sum=0;
for(int n=1;n<=100;n++)
if(n%3==0&&n%2==0)
sum=sum+n;

cout<<sum<<endl;
}

#include <stdio.h>

int main(void)
{
int iS = 0;

for(int i = 1; i <= 100; i++)
{
if((i % 3 ==0) && (i % 2 ==0))
iS = iS + i;
}

printf("%d\n", iS);

return 0;
}

#include<stdio.h>
void main()
{
int i,sum=0;
for (i=1;i<=100;i++)
if (i%3==0&&i%2==0)
sum+=i;
printf("the sum is %d\n",sum);
}
C语言编的

来个简明的
#include<stdio.h>
void main()
{
int i,sum=0;
