... allocation and deallocation: extern and static variables are allocated in the fixed data memory of the program, auto variables are allocated on the program stack, and register variables are allocated ... management resolves this problem by allocating and reallocating memory dynamically.

... 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...
