Define Wokeism

The subject of define wokeism encompasses a wide range of important elements. c++ - What does ## in a #define mean? In other words, when the compiler starts building your code, no #define statements or anything like that is left. A good way to understand what the preprocessor does to your code is to get hold of the preprocessed output and look at it. Is it possible to use a if statement inside #define?. As far as I know, what you're trying to do (use if statement and then return a value from a macro) isn't possible in ISO C... but it is somewhat possible with statement expressions (GNU extension).

Since #define s are essentially just fancy text find-and-replace, you have to be really careful about how they're expanded. I've found that this works on gcc and clang by default: What is the difference between #define and const?

This perspective suggests that, the #define directive is a preprocessor directive; the preprocessor replaces those macros by their body before the compiler even sees it. Think of it as an automatic search and replace of your source code. A const variable declaration declares an actual variable in the language, which you can use...

well, like a real variable: take its address, pass it around, use it, cast/convert it, etc. Difference between `constexpr` and `#define` - Stack Overflow. So I read the interesting answers about what are the differences between constexpr and const but I was curious about are the differences between #define and constexpr ? This perspective suggests that, i feel like constexpr is jus...

c - #Define VS Variable - Stack Overflow. #define WIDTH 10 is a preprocessor directive that allows you to specify a name (WIDTH) and its replacement text (10). The preprocessor parses the source file and each occurrence of the name is replaced by its associated text. The compiler never actually sees a macro name at all, what it sees is the replaced text.

c++ - 'static const' vs. It's important to note that, '#define' - Stack Overflow. Is it better to use static const variables than #define preprocessor? Or does it maybe depend on the context?

This perspective suggests that, what are advantages/disadvantages for each method? What is the purpose of the #define directive in C++?. 0 in C or C++ #define allows you to create preprocessor Macros. In this context, in the normal C or C++ build process the first thing that happens is that the PreProcessor runs, the preprocessor looks though the source files for preprocessor directives like #define or #include and then performs simple operations with them.
