Accessors (getters) and mutators (setters) are defined as you would define any member function, usually using the attribute's name prefixed with get_ or set_ as appropriate. Accessors are typically defined as constant member functions that return values (copies of attributes), but you can also return references and pointers to the actual attributes if required, even though these can both undermine encapsulation. However, returning constant references or contant pointers to constant types ensures encapsulation is maintained without creating any unecessary copies of an object (the caller can make a volatile copy when desired). Mutators typically accept a constant value, reference or pointer and act as a data validator, verifying that the incoming data is acceptable before physically setting the member. The return value of a mutator is often void, but when validation is not a concern, it can be useful to return the current value (prior to mutation), thus allowing the caller to easily determine if the object has been mutated or not.
C: there are no methods in C. C++: no.
In C++, overriding and function, method, or operator is a different thing than (dynamic) polymorphism, so overriding a polymorphic method is almost entirely possible.
An attribute is a class member variable while a behaviour is a class member method.
In C# only class instances can have a destructor, whereas both class and struct instances can have a destructor in C++. While syntactically similar, a C++ destructor executes exactly as written, whereas a C# destructor merely provides the body of the try clause of the class' finalize method.
c language is the structure oriented language and c does not follows the object oriented paradigms . c++ obeys the all object oriented language characteristics ========== C++ is a set of extensions to the C language to allow some (not all) principles of object-oriented programming to be used. Originally, C++ was a front end pre-processor for C and C++ compilers will translate C language functions.

In C++, methods are simply class member functions.

A declaration is an incomplete type whereas a definition is a complete type.
Use the istream::eof() method.
See related link. It's in C rather than C++, but conversion to C++ is fairly simple.

a squared plus b squared is c squared
Looping means you repeat a particular procedure a specified number of times or until a defined condition is met.
The term "4.23 plus 16.21" matches with definition A) 26.09. The term "42.3 plus 1.621" matches with definition B) 43.921. The term "4.23 and minus 1.621" matches with definition C) 20.44. The term "42.3 and minus 16.21" matches with definition D.
Hiding means a class cannot see the definition. Overriding implies that a class must see that to "override"
