不知道你的hello.c代碼是不是你寫的，我copy來執(zhí)行并沒有錯。

這是我的代碼：

#include?<stdio.h>
int?main()?
{?
????/*?定義需要計算的日期?*/
????int?year?=?2008;
????int?month?=?8;
????int?day?=?8;
????int?sum,i;
????sum?=?day;
????/*

????????????????????sum+=?29;
????????????????}else{
????????????????????sum+=?28;
????????????????}
????????????????break;
