我们可以使用宏去定义常量,当然我们也可以利用宏定义中运算 #include <stdafx.h> #include <stdio.h> #include <conio.h> #include <stdlib.h> #include <string.h> #define MULTIPLY(val1, val2)((val1)*(val2)) //这里定义了一个乘法运算的宏 void main() { int result; result = MULTIPLY (2,...
1. An inline function is defined by the inline keyword. Whereas the macros are defined by the #define keyword.2. Through inline function, the class’s data members can be accessed. Whereas macro can’t access the class’s data members.3. In the case of inline function, the program can...

The macro __PRETTY_FUNCTION__ reports a class name in static functions as well as method calls. However, this will only work with gcc. Here's an example of extracting the information through a macro style interface. inline std::string methodName(const std::string& prettyFunction) { size...

宏(Macro)本质上就是代码片段,通过别名来使用。在编译前的预处理中,宏会被替换为真实所指代的代码片段,即下图中 Preprocessor 处理的部分。 C/C++ 代码编译过程 图片来自 ntu.edu.sg 根据用法的不同,分两种,Object like 和 Function like。前者用
