Dynamic binding has two forms, static and dynamic. Statically-typed dynamic
binding is found in languages such as C++ (virtual functions) and Eiffel
(redefinition). It is not known which function will be called for a virtual
function at run-time because a derived class may override the function, in
which case the overriding function must be called. Statically determining all
possibilities of usage is undecidable. When the complete program is compiled,
all such functions are resolved (statically) for actual objects. Formal object
usage must have a consistent way of accessing these functions, as achieved thru
vtables of function pointers in the actual objects (C++) or equivalent,
providing statically-typed dynamic binding (this is really just defining simple
function pointers with static typechecking in the base class, and filling them
in in the derived class, along with offsets to reset the receiver).
The run-time selection of methods is another case of dynamic binding, meaning
lookup is performed (bound) at run-time (dynamically). This is often desired
and even required in many applications including databases, distributed
programming and user interaction (e.g. GUIs). Examples can be found in
[Garfinkel 93, p80] and [Cox 91, pp 64-67]. To extend Garfinkels example with
multiple-polymorphism, a cut operation in an Edit submenu may pass the cut
operation (along with parameters) to any object on the desktop, each of which
handles the message in its own way (OO). If an (application) object can cut
many kinds of objects such as text and graphical objects, multiple-polymorphism
comes into play, as many overloaded cut methods, one per type of object to bedrccx
cut, are available in the receiving vhvvmobject, the particular method being
selected based on the actual type of object being cut (which in the GUI case is
not available until run-time).

Explain the concept of late binding and dynamic binding with the help of at least two examples?
the concept of dynamic linking and dynamic binding with example
Static vs dynamic binding in c plus plus?
Static binding occurs at compile time. Dynamic binding occurs at runtime.
What is Dynamic testing of software application?
Dynamic testing is a term used in software engineering to describe the testing of the dynamic behavior of code. That is, dynamic analysis refers to the examination of the physical response from the system to variables that are not constant and change with time.
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 is dynamic binding in java?
Dynamic Binding means declaring variables at run time only rather than declaring it at compile time.
Is late binding and dynamic binding related to polymorphism?
Late binding and dynamic binding are related to runtime polymorphism. By contrast, compile time polymorphism is known as static binding. Template functions and classes are examples of static binding because the exact type can be determined at compile time.
When dynamic binding approach in oops?
at runtime
What is Difference between dynamic polymorphism and static polymorphism with example?
Static polymorphism is used the concept of early binding or we can say compile time binding where as dynamic polymorphism used the concept of late binding or run time 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.
What is binding in oops?
Binding is defined as the connection between the function call and the corresponding program code to be executed. There are two types of bindings. They are; 1.static binding and 2.Dynamic binding.
Which process of assigning a value to an attribute at the run time is?
Dynamic binding
What is the other name for polymorphism?
It is also called 'Dynamic binding of Function'
