#1 Is C++ Object Oriented Programming Language?

Long story short, C++ Is not a plain object Oriented language!

1. Classes may be created or modified during runtime, a feature that C++ does not support.

2. Some programming situations demand runtime creation of new classes:

1. If a large number of different classes are required to design the solution, then it will be efficient to create them at runtime as needed.

2. If all classes required at runtime are not known at compile time.

3. Requirements for new classes arise dynamically. In a programming language with statically created classes, it will be required to re-program with new classes and re-compile. This will lead to system downtime, which can be avoided by having support for runtime class creation.

In C++, a class is completely defined by a syntactic construct and once it is defined, it cannot be modified in runtime. In contrast, programming languages Smalltalk supports that the classes are created by a sequence of runtime steps. When a method is added, it is compiled right away and added into the development/runtime environment immediately and is available for use in subsequent programming steps. This is what c++ lags in, that's why C++ is not a purely object oriented programming language!

#2 Is C++ Object Oriented Programming Language?

C++ is not a pure OOPL. In C++ friend functions allow access of private data outside the class,which is against OOPL features.

C++ allows writing global functions, outside of any class, while in C# and Java all methods (functions) must be
included in a class.

1. According to the "Pure" object oriented principle, no method/routine should exist without the object. In C++, main () method can be independent and does not need any class but Java/C# its static method of "some" class.

C++ provides "Friends" which is absolute corruption to the OO-Principle of encapsulation.

According to OO-Principle, one object should have only one hierarchical parent reference. In C++, Multiple-Inheritance contradicts this principle.

According to OO-Principle, everything needs to be objective. C++ provides inbuilt data type- int,float etc which are not objects in their nature. C#/Java also provides the same kind of datatype but its inner presentation is always objective. For example: in java you have got wrapper classes and in C#, all these types are derived from System.ValueType object.

#3 Is C++ Object Oriented Programming Language?

Yes, because C++ contains object oriented programming features like inheritance,encapsulation etc..

#4 Is C++ Object Oriented Programming Language?

In C++ Also object Oriented Programming Language But It is not purely Object Oriented Programming Language B,ze. In C++ Some Cases We Can Write Without Class. But In Java We can't write without class.

#5 Is C++ Object Oriented Programming Language?

No, C++ is not a pure object oriented language its extension is c# is a pure object oriented language. because in C++,the methods can be written outside the class whereas in case of c# we can access any class members or methods can be accessed by only objects.
