我写的一个C++万年历，有点毛病，请高手给我修改一下。(100分送上)
万年历的功能还没有实现。实现一个万年历分三栏输出。
大概发现有以下错误。
- C/C++ code
if(n%7==0) break;
这条语句就好像是不起做用似的。
因为找不到原因，所以下面的工作好多还没有做。
如果改的好的。我会送上100分。(请尽量不要修改太多的代码，也就是说整体的尽量不要改，细节问题可以改一下。)

[解决办法]
你在上面int n = 0;
然后下面 n++；
那每次n必然等于1啊
if(n%7==0)
break;
这个break当然永远进不去。你应该把int n = 0;这句放到循环外面

显式格式你再调一下

另外,尽量使用
#include<iostream>
#include<iomanip>
using namespace std;
