![]() You usually name your #include guard the same as the name of your header file. The most common way to define an include guard is as follows: //File: Aircraft.h Using a include guard, you can prevent a header file being included multiple times during the compilation process. ![]() When the preprocessor sees a #include, it replaces the #include with the contents of the specified header. Mistake # 1: Not using “include guards” in a header file. Here’s a short description of the top 10 header file issues that can crop up if you’re not careful and how to avoid them. The larges your C++ project is, the more important this becomes. However, not having the correct header file design decisions can have significant ramifications on your project in terms of increases build times, compilation fiascos, code maintainability issues and plain information leakage. It’s not an academically stimulating subject to teach, so most CS programs do not emphasize header file design in their courses. Talking about header files is not as interesting as discussing complex search algorithms or debating design patterns. C++ header files is a rather mundane topic by most standards. ![]()
