I have a Class "Parent1" and another "Parent2", which symbolize different hardware implementations of a device "Subclass". What is the most elegant way of implementing this? I have thought about using templates e.g. class Parent1{ public: Parent1(): void run(); }; class Parent2{ public: Parent2(): void run(); }; template<typename Parent> class Subclass : Parent { public: ..

if I have a copy constructor in which the class is being passed by reference for example #include <iostream> #include <string> using namespace std; class Move { private: int* data; public: Move(int d); Move(const Move& source); ~Move(); move get_value () {return *data;} }; Move::Move(int d) { data = new int; *data = d; } Move::Move(const ..
Wanting to write a c++ craps. As I did it before with java years ago, I want to make it more that just a dice roll simulator. The main problem (and most likely the biggest problem because of the simplicity of craps that can mostly be made with random number, a bit of addition, a ..
Here I implemented a c++ program using OOP concepts. Let’s say there are 1000 salesmen (1000 Salesman Class objects) in a company. If I want to print the name of each and every salesman (using a loop or something), how to do it? Not only for printing the name, let’s say the company wants to ..
I am trying to create some variables based on the following instructions. I am new to c++ and I don’t understand pointers that well. Here are the directions for the variables I am supposed to make. •videoGamesArray – a pointer to an array of pointers. Each pointer in the array should be able to point ..
I am trying to make a copy constructor for an Object that contains a pointer, that pointer refers to other pointers etc. The following code is a Binary Tree. BTree.h { public: vertex* root; BTree() { root = NULL; }; ~BTree() { delete root; root = nullptr; }; BTree(const BTree& p_BTree) //copy constructor { root ..

I work on a code written by someone else which unfortunately I have no access to. The code is written mostly in C#, but the calculation algorithms are in C++. At a certain part of the code, some instances are created to receive input values from excel, for example: // initialize input & output structures. ..
