Virtual Base Class / Diamond Problem in C++ Ø   When we try to implement multiple inheritance or multipath inheritance multiple base classes are inherited that are also inherited from same super-base class. §   An element of ambiguity can be introduced into a C++ program when multiple base classes are inherited. Ø   For example: - #include<iostream> using namespace std; class Base {       public:              int a; }; class D1:public Base    // D1 inherits Base {       public:               int b; }; class D2:public Base    // D2 inherits Base {       public:              int c; }; class D3:public D1, public D2  ...

What is object slicing in c++ ? When a Derived Class object is assigned to Base class, the base class' contents in the derived object are copied to the base class leaving behind the derived class specific contents. This is referred as Object Slicing. Class Base { public: int i; }; class Derived : public Base { public: int j; }; int main() { Base Bobj; Derived Dobj; Bobj = Dobj; //Here Dobj contains both i and j. //But only i is copied to Bobj. } Object slicing is a concept where additional attributes of a derived class object is sliced to form a base class object. Object slicing doesn't occur when pointers or references to objects are passed as function arguments since both the pointers are of the same size. Object slicing will be noticed when pass by value is done for a derived class object for a function accepting base class object. Object slicing could be prevented by making the base class function pure virtual there by disallowing objec...
