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.

Static vs dynamic binding in c plus plus?
Static binding occurs at compile time. Dynamic binding occurs at runtime.
Does c and c plus plus support static or dynamic binding?
Yes and no. Static vs dynamic binding is not a C or C++ language issue; it is a linker issue. If you link with a .lib file that contains stubs for run-time loading, then the called routine will not be loaded until it is invoked, and it will not be made a part of the load module.
Why dynamic binding is not possible for normal C functions?
Dynamic binding is certainly possible for normal C functions. Binding is a function of the binder (linker) and has nothing to do with the language itself.
What are the various concepts of c plus plus?
1.Classes and Objects 2.Constructors and Destructors 3.Inheritance 4.Polymorphism 5.Dynamic Binding
Why does C plus plus allows static binding and not dynamic binding?
Dynamic binding, or late binding, is when the object code for the class does not get loaded into memory until it is needed. This saves time at module load time, at the cost of delayed execution for the first invocation.
Which binding in C plus plus is preferred and why?
There is no preference as such. The type of binding you use is more dependant upon the design and circumstance rather than any preference you may have. Static binding is certainly more predictable and therefore easier to program, but dynamic binding offers much greater flexibility.
What is dynamic binding c?
to bind a function at run time is known late binding .but still i don't know how to achieve it..?please anyone reply
Why c plus plus is not complete object oriented language?
because c++ supports all the basic concepts of oop :1.objects,2.classes,3.data abstraction and encapsulation,4.inheritance,5.polymorphism,6.dynamic binding,5.message passing.
How ploymorphism and inheritance is different from that in Java and c plus plus?
C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick. For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.
Is overriding a dynamic polymorphism in c plus plus or not?
In C++, overriding and function, method, or operator is a different thing than (dynamic) polymorphism, so overriding a polymorphic method is almost entirely possible.
How is dynamic initialisation achieved in c plus plus?
The C++ standard has this to say about dynamic initialisation:"Objects with static storage duration shall be zero-initialised before any other initialisation takes place. Zero-initialisation and initialisation with a constant expression are collectively called static initialisation; all other initialisation is dynamic initialisation."
C plus plus uses dynamic memory management?
No, C++ does not use dynamic memory management. The programmer is entirely responsible for releasing dynamic memory when it is no longer required. When static objects fall from scope, their destructors are called automatically, but there is no automatic garbage collection for dynamic objects. Allocated memory remains allocated until the programmer manually releases it, or the thread that owns the memory is terminated.
