Re: [Dev-C++] using assert

[Wobien <wo...@pl...>]

Thanks Daniel and others for your suggestions.

The #define NDEBUG suggested by jo mateix works fine to prevent the
assertions to compile.

I already tried to run my program from the DOS prompt, but I did it by
closing Windows and start computer in DOS mode. When I do that I get "This
program cannot be run in the DOS mode".
When I do it the way Daniel suggests it works fine, and I can read the
message.
