ok sorry for this long code ...

it show me bunch of errors

welcome! This is too much to read without any formatting. Edit your post and put in code tags, the <> on the side bar editor or the word code in [] brackes and [/] to end the code block.

also, describe what it should do and what it does wrong. "this giant block of random code does not work" is not helpful. "this crashes when I type in blah" or "this says 23 and should say 42" would tell us a lot more

PLEASE learn to use code tags, they make reading and commenting on source code MUCH easier.

http://www.cplusplus.com/articles/z13hAqkS/

HINT: you can edit your post and add code tags.

[George P]

why this program is not working ?

Does the code compile? If not, what errors are you getting?

If it does compile what is your EXPECTED output, and what output are you actually getting?

We are not in the room with you, looking at your computer screen. You have to tell us in more detail what is going wrong.

@jonin and @Furry Guy: The OP did state his issue:

1>calendarType.obj : error LNK2019: unresolved external symbol "public: class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >
1>calendarType.obj : error LNK2019: unresolved external symbol "public:
1>calendarType.obj : error LNK2001: unresolved external symbol "public: static class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > * dayType::weekDays"

@OP: The linker is telling you that it can't find certain symbols when it tries to link your program. The linker errors are coming from calendarType.obj, however you did not provide the source for calendarType.cpp so we can't reproduce your problem.

PLEASE ALWAYS USE CODE TAGS (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your post.

Hint: You can edit your post, highlight your code and press the <> formatting button.

@AbstractionAnon,

The OP edited their post after our replies, the errors weren't there when we replied. What I quoted was edited out.

If only they had edited the post and added code tags.
