Question

I’m new at C++ and I am missing some terminology (couldn’t ask a specific question to Google), so I’ll try to be as clear as possible.

Let’s say I have instantiated an object of class A. Then say, from a method of this object of class A, I create an object of class B.

In my class B, i want to use the object of class A as an argument (passed by reference if possible).

Is that possible?

Thanks.

Yes, in your method of class A you can reference the current instance of A using the keyword this. For example, you can provide this for class A to the constructor of class B.

My C++ syntax is a bit rusty, so here’s a C# example that can be translated fairly literally to C++:

public class A
{
    public void MyMethod()
    {
        B b = new B(this);
    }
}

public class B
{
    public B(A parent) { // Do something with A, maybe store it in B for later reference
    }
}
