What does this code do in C and what prints in console: printf (#variable##”hello”) ?
Oh, I see. Are there any other preprocessor directives in C that I should know about?
Yes, there are several preprocessor directives in C, including #define, #include, and #ifdef. #define is used to create macros that can be used throughout the program. #include is used to include headers that contain function declarations and definitions. #ifdef is used to conditionally compile code based on whether a certain macro is defined or not.
