This code does not compile on any platform, because of lines 24 and 25. Do you see what's wrong with them?

Aside from that, your code should work just fine. It works on the related darwin platform.

Correct, on line 24 and 25 is constants without declaring type of constants. I just change const cyear=2008; and const cnon=1; in const int cyear=2008; and const int cnon=1; and now it is working fine!

thanks!
