How do I know if I can/should use it?.How do I tell Code::Blocks that it is my compiler? 3 Q: I have downloaded MS VC++ Toolkit 2003 for a compiler.2 Q: My project should be compiled with a custom makefile.1 Q: What compiler can I use with Code::Blocks?.So, I haven't really understood what or why the error is/happened. This time, when compliled and run, it worked just fine. The next morning, I decided to create a console project and I added the same files that I had already written into the new project (without changing a single line of code!). Instead, I got the following error message: undefined reference to course, at first I thought I had miscoded something somewhere, but after 30 minutes of thorough checking the code was fine. This time, however, when I compiled and ran the files it didn't work. Then the tutorial dictated that the GradeBook.h file should be itself split into 2 parts: GradeBook.h containing the class's interface (prototypes), and GradeBook.cpp, which contained the member function definitions for the GradeBook class in the header file. Again, after compiling and running, it worked just fine. Then, as the tutorial instructed, I split the code into main.cpp and GradeBook.h. When I compiled and ran the code, it worked just fine.

I hadn't created a project in Code::Blocks, I just created a new empty file, and coded away. There was only one page of code named main.cpp. I was following a tutorial for a console application. But what I'd like to know is why the error happened in the first place. Anyway, I had an issue that I have now resolved.

I've just started learning c++ (so you could call me a novice!).
