C++ Neon Compiler Error: INT_MAX was not declared in this scope/could not be resolved. [message #1728758]

Hi all!

I'm new to Eclipse and trying to brush up on C++ that I took a looooong time ago. I'm going through John Purcell's "Cave of Programming" series, and everything was going without a hitch until I hit the 9th video on integer types. This code worked for him, but not for me. Any ideas of what behind the scenes settings I need to change?

Thanks in advance! Smile

INT_MAX is defined in <climits> or <limits.h>. <limits> contains the std:::numeric_limits class.

Thank you, David. I actually discovered that the solution was to replace limits with limits.h before my thread was approved by the moderators. I got a little tripped up by the fact that I'm using Windows and the instructor is using a Mac.

Thanks again!
