An example of a virtual function with C++ Let’s see what a virtual function in C++ looks like in action. class Pet { public: virtual ~Pet() {} virtual void make_sound() const = 0; }; class Dog: public Pet { public: virtual void make_sound() const override { std::cout <<...
Hence, using pointers of Base classes (higher in an inheritance heirarchy) can be assigned to objects of derived classes and can be used in a unified manner with the use of virtual functions. Hence, Polymorphism. (The plus "+" operator example used above would not be correct, as that ...

friend return_type class_name::function_name (arguments); // for a member function of another class class intellipaat{ friend int intellipaat_Function(paat); statements; }In this example, friendFunction is declared a friend of the MyClass class and can access its private member, privateData....
While this example may seem trivial, the general structure for the problem is the same as for more complicated real-life races. There are four conditions needed for a race to be possible. The first condition is that there are memory locations that are accessible from more than one thread. ...
What better way to explain than with an example? Let’s take a simple expression 4+5 = 9. Here, 4 and 5 are called operands, and ‘+’ is called the operator. Solidity supports a few types of operators like: Arithmetic Operators: Addition (+), Subtraction (-), Multiplication (*),...

Neither of these worlds is virtual, but the idea of exploring and navigating the two simultaneously does, nevertheless, have things in common with virtual reality. For example, how can a mobile device figure out its precise location in the world? How do the things you see on the screen of...
