C++ Protected / Public overloads

Question

I have a class like this :

class Foo
{
public:
    Foo()
    {
        for(int i = 0; i < 10; ++i)
            v.push_back(i);
    };
    const vector<         


        

Answer 1

Since foo is not const compiler is trying to use the non-const method. As a workaround you can do the following:

    Foo foo;
    const Foo& cFoo = foo;
    for(int i = 0; i < (int) cFoo.V().size(); ++i)
    cout << cFoo.V().at(i) << endl;
