We can define a function like Macro, in which we can pass the arguments. When a Macro is called, the Macro body expands or we can sayMacro Call replaces with Macro Body. Now, the important thing is that:How Macro arguments evaluate?-"Macro arguments do not evaluate before Macro expansion...
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,...
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。前者用于 Object 对象,后者用于函数方法。 C/C++ 代码编译过程中,可通...
