Why am I getting “error: expected '}'” in C++ but not in C?

Question

I\'m getting \"error: expected \'}\'\" where the \'^\' is pointing when I compile in the following C++ source:

typedef enum { false, true } Boolean;         


        

Answer 1

false and true are C++ keywords, so you can't use them as enum identifiers.

In C they are not keywords so your code will work, but if you include then it will fail to compile because that header defines false and true as macros.

Note that you probably shouldn't implement a boolean type yourself. C++ already has the bool type, and if you are using a C99 compiler, you can include stdbool.h. This will give you a bool type that has false and true values, similar to C++.
