In C language, functions are also a type of “object”, which have addresses in memory. Therefore, it is possible to define pointers to functions, which can be used for dynamic calls, callback handling, building function tables, etc. Mastering function pointers is key to understanding the “low-level abstraction” and “modular programming” in C language. 1. Basic … Read more
