The article considers using multiple inheritance in C++ programs. A single inheritance with various classes is provided to elaborate the conversion of a pointer to an object into a pointer to its public inherit
Kindly explain "What is the use of Inheritance? and When to use?" with respect two below programs. Why I cannot get output from 1st program after using class initialization? Program 1: classProgram { classShape { publicvoidsetWidth(intw) { width = w; } publicvoidsetHeight(inth) { heig...
class C : public A,public B { //Implementation }; The inheritance rules and the usages of access specifier for each base class member remain the same as in single inheritance. The access to each base class member is independent of the access to the members of other base classes using whic...

In general, it is not allowed to call the grandparent’s constructor directly, it has to be called through parent class. It is allowed only when ‘virtual’ keyword is used. As an exercise, predict the output of following programs.
