问题描述
是否可以用空格编写define，例如:
Is it possible to write define with spaces such as:
#define replace to replacement here
我想将replace to"替换为replacement here".
我想测试私有成员:
我确实写过
#define private public
但它不适用于 Qt 中的私有插槽
but it didn't work for private slots in Qt
所以我打算使用类似的东西
so my intend was to use something like
#define private slots: public slots:
无论如何，我找到了另一种测试插槽的方法，顺便说一下，我知道这是一个丑陋的 hack.
anyway I have found another way to test slots and by the way I'm aware of that this is an ugly hack.
推荐答案
不，你不能
#define identifier something
你定义的必须是一个不能包含空格的标识符.也不能包含连字符、以数字开头等，只能定义标识符
what you define must be an identifier which cannot contain space. Nor can it contain hyphen, begin with a number, etc. you can define only an identifier
你写的会起作用
#define replace to replace here
但不是你所期望的.这一行定义了 replace 被替换为 to replacement here
but not as you expect. This line defined replace to be substituted with to replacement here
