Detailed Explanation of Inline Functions in C++

A key feature of C++ is the inline function. Therefore, let’s first understand the usage and intended applications of inline functions. When a function is declared as an inline function, the compiler will replace the location of the function call with the definition of the inline function at compile time. Any changes to the inline … Read more

Detailed Analysis of Inline Functions in C++

In C++, to avoid the overhead caused by function calls (mainly parameter stack pushing, jumping, returning, etc.), one can use the inline function mechanism (<span>inline</span>) to directly replace the function in the calling place during the compilation phase, similar to macro expansion in C language, but safer and more controllable than macro functions. Below, we … Read more
