Use inline wisely Inline Function ------ a wonderful idea! They look like functions and operate like functions, which are much better than macro (macro) (see clause 1) and do not have to bear the overhead of function calls when using them. Can you have more requirements on them? However, you actually get more from them than you think, because avoiding the overhead of function calls is only a problem. To
1: Definition: They look like functions and operate like functions, which are much better than macro functions and do not need to bear the overhead of function calling. When a function is inline, the compiler can optimize the function body in a specific environment. Such optimization is impossible for "normal" function calls.

Before introducing inline functions, it is necessary to introduce a preprocessing macro. The functionality of an inline function is similar to the functionality of a preprocessing macro. I believe you have used preprocessing macros, we will often define a number of macros, such as
