C++ question: foo object as a parameter for a method of class foo

dcc24 · 2010-07-11 11:07:51

I'm starting to learn C++ and I have a question. It's probably ridiculously simple

Let's say I have a class "Foo". There is also a method "bar" of class "Foo". For example:

class Foo {
    public:
        Foo () {};
        void bar();
};

I'd like to pass another object "Foo" as a parameter to "bar". i.e:

class Foo {
    public:
        Foo () {};
        void bar(Foo f);
};

Is this possible? If yes, how?

yes, just like you prototyped should work.

Well, it didn't. Dunno why Passing a pointer of that object, however, compiles fine. i.e:

class Foo {
    public:
        Foo () {};
        void bar(Foo * f);
};

Or you could solve it with references:

class Foo {
    public:
        Foo () {};
        void bar(Foo &f);
};

#test.cpp

class Foo {
      public:
            Foo () {};
            void bar(Foo f) {};
};

int main()
{
      Foo test;
      Foo test2;
      test.bar(test2);
}

Just had to test making a complete cpp-file. That compiles and runs absolutely fine in both GCC 4.5.0 and 4.0.1. (Which is what I had quickest access to to test this). So I am not sure why it wouldn't work for you.
