... constructor passes to it its own parameter, character array; and the copy constructor passes to allocate() its parameter's character array s.str. When one object initializes another object, a copy ... argued against passing objects to functions as value parameters or as pointer parameters and promoted passing parameters by reference instead. I explained that pass by reference is al...

... rather than one-to-many: Class Stack needs a Node object that is instantiated to the same actual type as class Stack itself. A good way to achieve that is to define class Stack as a template ... object code. Instead of heap memory allocated at instantiation (or at array overflow), the Stack class can allocate a Node object every time data is pushed on the stack and deallocate the...
