All virtual functions (including pure-virtual functions) are represented in italics. All non-virtual functions are represented normally. There is no differentiation between pure and non-pure virtual functions, however some people append "=0" to distinguish the pure-virtual functions.
What else can I help you with?
Write abstract class in c plus plus?
An abstract class is any class definition that contains at least one pure-virtual function. class AbstractClass { public: virtual void DoSomething()=0; // Pure-virtual. };
What is the difference between friend function and inheritance in c plus plus?
There is no such thing. When declaring a friend function only the explicitly-scoped friend is granted private access. The friend function may well be declared virtual within its own class but none of its overrides are granted access unless they are explicitly granted access.
Explain virtual functions in C plus plus?
A virtual function in C++ is a function that can have multiple definitions.For example:If you have a class which contains a virtual function:class Virtual{virtual void makesomething();};That function can be implemented when you inherit that class an implement the function. So:class Inherit : public Virtual{//this is the same function, but can be implemented to do something differentvoid makesomething() { //do something else }};
What is virtual function in c plus plus?
A virtual function is a member function of a class, whose functionality can be over-ridden in its derived classes. It is one that is declared as virtual in the base class using the virtual keyword. The virtual nature is inherited in the subsequent derived classes and the virtual keyword need not be re-stated there. The whole function body can be replaced with a new set of implementation in the derived class
Does the C plus plus programming language use a virtual machine?
No, it does not. But Microsoft Visual Studio 2008 allows you to connect to a virtual machine and run your projects "sandboxed".
How dynamic binding acheived in c plus plus?
Dynamic binding is achieved via virtual functions and the virtual table that is associated with every class that declares or inherits a virtual function. The virtual table (or v-table) maps every virtual function (including pure-virtual functions) to a function pointer that points to the most-derived overload. This makes it possible to invoke specific behaviour even when the runtime type of the object is unknown to the caller.
Write abstract class in c plus plus?
An abstract class is any class definition that contains at least one pure-virtual function. class AbstractClass { public: virtual void DoSomething()=0; // Pure-virtual. };
Does y equals 3x2 plus 2x-3 represent a function?
Yes.
Does the equation y equals 2x plus 1 represent a function?
The [ 2x + 1 ] represents a function of 'y' .
Does equation y 2 plus 1 represent a linear function?
Without an equality sign it is not an equation.
What is the difference between friend function and inheritance in c plus plus?

How does c plus plus endeavor to represent the object oriented paradigm?
C++ endeavours to represent the object oriented programming paradigm through the use of classes. The four main pillars of OOP are encapsulation, inheritance, polymorphism and abstraction, which C++ primarily achieves through the use of classes, class hierarchies, virtual methods and templates.
Does the C plus plus programming language use a virtual machine?
No, it does not. But Microsoft Visual Studio 2008 allows you to connect to a virtual machine and run your projects "sandboxed".
Is y plus x2 plus 1 a function?
That is not a function, although it does involve the function of addition. A function is something that is done to numbers.
A c plus plus statement that invokes a function is known as?
...a function call.
