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.
What do you meant by Runtime Polymorphism?
Runtime polymorphism is also called as method overriding, late binding or dynamic polymorphism. It is when a method in a subclass overrides a method in its super class with the same name and signature.
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
What is dynamic dispatching?
Dynamic dispatching, also known as late binding, is a technique used in object-oriented programming where the method to be called is determined at runtime based on the actual type of the object, rather than at compile time. This allows for flexibility in the behavior of objects and enables polymorphism.
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 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 the difference between Late binding and early binding?
Early binding. The type of the instance is determined in the compile time. It follows that the static (declared) type of the pointer or reference is used. This is the default for all methods in C++, C, or Object Pascal.Late binding. The type of the instance is determined in the run time. It follows that the actual type of the instance is used and the method of this type is called. This is always used for the methods in Java. In C++, the virtual keyword denotes the methods using the late binding.Late binding gives the class polymorphic behavior. On the other hand, late binding is less effective than early binding, even though the difference may be negligible. (In C++ on PCs, the difference between the late and the early binding is usually one machine instruction per method call.)Any method that might be overridden in any of the derived classes should use the late binding.Note:In C++ and other OOP languages in which the late binding must be declared, the classes containing at least one virtual method are called polymorphic classes. Classes without any virtual method are called non-polymorphic classes. In languages like Java, where all the methods use late binding by default, all the classes are polymorphic.
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.
What is the difference between dynamic loading and late binding in C plus plus?
Late binding occurs when the compiler does not have enough information to verify a method exists for a given function signature and therefore cannot bind that method to its allotted slot in the v-table. The method must instead be located by its name at runtime, which will incur a performance penalty every time that method is called. Early binding is more efficient and is therefore the preferred method of binding virtual methods, but late binding exists to cater for those cases where early binding is simply not an option. Dynamic loading occurs when a library may or may not be available at compile time and must be loaded at runtime. All symbols exposed by the library must therefore be resolved at loadtime. If the library is not available at loadtime the program should be engineered to provide a graceful fallback. Dynamically loading libraries that also rely on late binding should be avoided wherever possible, but it may be the only solution available in some cases.
What is Dynamic Linkage?
In operating systems exists static and dynamic linking. When a program uses static linking, the task of linking libraries to the program is done in compilation time, so the binary image of these program includes the library linking that will use. Otherwise in a dynamic linking model, the program will link the libraries that it needs at run time, so with this model the program will have the hability to choose with library to use at runtime. I.e. in most common .net programs the external libraries (dlls) are linked at run-time, so you will have the posibility to update one of these dlls if the dlls interface definition keeps as oldest. The common use can be with a new dll version that solves some bugs or improves performance issues.
