Maybe you should put the code in 
[code][/code]
 and tab it for the others debug it easily.

And you should tell us what does the program do, and what's the bug you're facing.

Please use code tags and intuitive indentation. They make the code much more readable. See http://www.cplusplus.com/articles/jEywvCM9/


Error? What error? You must know something more specific. When does the error occur? How does it show itself? It is much easier for us to search, if you hint what we should be looking for.


While the use of goto may not technically be an error, it is a very bad and error-prone practice.
AbstractionAnon (6954)
Line 1: Correct header for modern compilers is <iostream>, not <iostream.h>

Line 3: Missing using namespace std;

Line 35: month[12] has too many initializers.

Line 49: i is undefined. use int i in your for statement.

PLEASE 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.
