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

The true and false are keywords in C++. You cannot use them in enum identifiers.

As it is said in the standard :

2.12 Keywords [lex.key]

The identifiers shown in Table 4 are reserved for use as keywords (that is, they are unconditionally treated as keywords in phase 7) except in an attribute-token.

In table 4:

 false
 ...
 true

In C, they are not keywords, your code should work but the best should be to include who already defines true and false then you don't need to define them by yourself.
