Inline Functions in C: Enhancing Performance In C, functions are an important way for us to encapsulate code and achieve reuse. However, in certain cases, calling a function may incur some performance overhead. To address this issue, C provides a very useful feature—Inline Functions. This article will explain in detail what inline functions are, how … Read more
1. Basics of Macro Definition: The Essence of Text Replacement A macro is one of the core functionalities of the C language preprocessing phase, and it is essentially text replacement, expanded by the preprocessor before compilation. Basic Syntax #define macro_name replacement_text Example: #define PI 3.1415926 #define MAX(a, b) ((a) > (b) ? (a) : (b)) … Read more
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
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
