An argument is usually a string passed into an exe.

A parameter of a function is copied on to the stack of a function when the function is called.

Pointer is a memory location which contains a memory location.

A reference is a pointer which is passed into a function. I.E. it cannot be changed

Shallow copy is a copy to the stack, I.E. out of scope the variable is destroyed.

Deep copy is a copy to allocated memory. I.E. has to be freed to be destroyed.

Default copy copies the class members but does not copy data which is pointed to by internal pointers.

Overloaded copy is a copy which you define so you can define its behaviour.

This is my understand of these terms.
Hope this helps you.
