有的时候为了程序的通用性,可以使用#define预处理宏定义命令,它的具体作用,就是方便程序段的定义和修改。举个例子吧,如果说你在做一个项目,这个项目的代码很长,有5000多行,而且基本上里面的同一个常量N就占了3000多行,如果说今后你要是想对这个常量N的值进行修改,如果在程序的开始没有定义一...

define IN define OUT 这些宏定义的主要用途是作为修饰符,用于标记函数参数的类型。例如:void function(IN LPARAM lParam, OUT WPARAM outparam);这里的IN和OUT不表示任何具体的值,只是起到修饰作用,说明lParam是一个输入参数,而outparam是一个输出参数。这样的定义方式不仅有助于开发者快速理解代码...

2.内联函数(in line function) 宏在某些场合能得到类似于函数的功能,如下是一个常见的例子:#define ADD (a b) ((a)+(b)) cout<<“1+2=”<它将实现数据求和功能而输出:但我们至少有一打理由拒绝使用它,以下是最明显的: ①宏缺少类型安全检测,如: ...
