Although macros have many types, we will demonstrate the use of object-like macros and function-like macros in this article. The macros can be utilized in the C codes using the define keyword. The best and most maintainable solution to do resource management is to write that part of the code in C++, so that you can use the RAII idiom, or at least use templates and lambdas. The Macros in C language come in handy when swapping your large code with a single piece of line code to avoid complexity and more. ![]() However, this approach might not be very good for debuggability – this will depend a lot on your particular tools though. ![]() By using variadic macros, the usual errors about commas in the arguments will not occur. Some languages, such as C and C++, provide a way to define and invoke preprocessor macros which expand into strings of tokens.
