I want to use reverse c++. but it doesn't work

Please provide detailed information about the failure you experienced.

There are a couple of bugs in the parser:

The 'class' type qualifier is not recognized on instance variables, or as parameters:

class foo {
    public: class foo * foo( class foo * f ) const { return f; }
};

In this case class foo * is required because there is a method named foo. This is an issue in many header only c++ packages, and is especially pernicious with forward decls, and with external subsystems like bison.

Visibility statements won't work if there is nothing in between (or if they are made in visible by the preprocessor or comments:

class foo {
protected:
    // nothing here!
public:
    virtual void bar() const;
};

That code is totally valid and should not generate an error. The empty protected: statement should just be interpreted as a null statement.
