I’ve got the following class structure where AnotherPlayer is the child of SomePlayer. I have the method getInternalMove implemented in SomePlayer and overridden it in AnotherPlayer. It is called inside getMove. But when I call AnotherPlayer::getMove it doesn’t call getInternalMove in AnotherPlayer. What am I missing? According to this question, it should call `AnotherPla Note: ..

My code: Animal.h #ifndef ANIMAL_H #define ANIMAL_H #include <Cat.h> #include <iostream> using namespace std; class Animal { public: Animal( ); void setName(string n); virtual string getAnimalType(); //abstract method string getName(); virtual void makeNoise();//abstract method private: string name; }; #endif // ANIMAL_H Animal.cpp #include "Animal.h" Animal::Animal() { } void Animal::setName(string n) { name=n; } string Animal::getName() ..
Suppose i have a socket class: class Socket{ public: … Some Code … Socket(int type){ isServer = type; //some code } virtual void Send(string s); virtual void Send(string s, int clientID); … Some Code … private: int isServer; }; This is to be used both as a server and client. Now I need to have ..
What is abstraction implemented at the class level in C++? Is it different from the abstraction realized at the level of classes and interfaces in C# and Java? Are there any significant differences between the three languages in this case? Source: Windows Que..
I have been trying to develop a single header library-ish file that has all the code needed to setup and abstract window creation as well as OpenGL basic type abstraction to the apps needs. Everything has been going smoothly up to now, until I tried to move the window around. The context seems to just ..
I try to build a Customer manager program in c++. In my program, there is Customer class (base class), Guest (derived from customer), VIP (derived from Guest), a vector<Customer*> array in the main to store all customers. So if I want to promote a Guest object from the vector, what is the best way of ..
According to what I have learned, Abstraction is a concept of hiding internal implementation. We can achieve abstraction in java with interfaces, abstract keyword(for class/method) as well as through methods. eg Scanner s = new Scanner(System.in); int x = s.nextInt(); Here we need not know anything about nextInt() method. So I can say this is ..
The More General Question I am wondering if there is a standard way that operating systems / desktop managers use to expose the user’s preference regarding the placement of the window frame controls (Close, Maximize/Miniaturize, Minimize). For platforms like Windows and MacOS, it’s "pretty" safe to assume that the users wants their window controls on ..
I am currently working with a a class, and three other classes that derive from that base class. The base class is supposed to be essentially abstract, so that I can call the virtual function of a base class, and have it do the expected function of the derived class. My end goal is to ..
Let’s say I have the following class: template <typename T> class SomeClass : Parent<T> { public: // I have a function such as this one: T DoSomething(const T &t) { return t.DoSomething(some_data); } // But `T` might be a pointer, so sometimes I will need something like the following // instead (which obviously doesn’t work ..
