Difference between Static and Dynamic Binding in C++

I think main difference is as per name suggest static binding is static and dynamic binding is dynamic means more flexible. Does both static and dynamic bonding related to polymorphism? I guess no.

Difference Between Static Binding and Dynamic Binding

Binding generally refers to a mapping of one thing to another. In the context of compiled languages, binding is the link between a function call and the function definition. Consider below code where sum function is overloaded to accept two and three integer arguments. Even though there are two functions with the same name inside ComputeSum class, the function call sum binds to the correct function depending on the parameters passed to those functions. This binding is done statically during compile time.

Binding refers to the link between method call and method definition. This picture clearly shows what is binding. For every method call there should be proper method definition. If compiler does not see the proper method definition for every method call, it throws error. Static binding is a binding which happens during compilation.

Name binding

Machine languages have no built-in notion of identifiers, but name-object bindings as a service and notation for the programmer is implemented by programming languages. Binding is intimately connected with scoping , as scope determines which names bind to which objects — at which locations in the program code lexically and in which one of the possible execution paths temporally. Use of an identifier id in a context that establishes a binding for id is called a binding or defining occurrence. In all other occurrences e. An example of a static binding is a direct C function call: the function referenced by the identifier cannot change at runtime. Since the specific type of a polymorphic object is not known before runtime in general , the executed function is dynamically bound. Take, for example, the following Java code:.


If it's already known before runtime, which function will be invoked or what value is allotted to a variable, then it is a 'static binding'. if it comes to know at the.

It allows building software using objects. There are many objects in a software system or a program. These objects have attributes and methods. Attributes describe the characteristics.

Сьюзан стало абсолютно очевидно, что план Танкадо ужасным образом рухнул. Он не собирался умирать. Он рассчитывал, сидя в испанском баре, услышать по Си-эн-эн пресс-конференцию об американском сверхсекретном компьютере, способном взломать любые шифры.

Если бы не он, мы бы до сих пор взламывали шифры с помощью карандаша и бумаги. А теперь уходите! - Он повернулся к Бринкерхоффу, с побледневшим лицом стоявшему возле двери.  - Вы оба. - При всем моем уважении к вам, сэр, - сказала Мидж, - я бы порекомендовала послать в шифровалку бригаду службы безопасности - просто чтобы убедиться… - Ничего подобного мы делать не будем. На этом Мидж капитулировала: - Хорошо.

    Events occur at run time are "Dynamic Binding".

    In static binding, the function defination and the function call are linked during the compile-time whereas in dynamic binding the function calls are not resolved until runtime. Dynamic binding happens when all information needed for a function call cannot be determined at compile-time.
