When we call C functions from C++, we need to useextern "C". This is because C++ allows functionoverloadingwhile C does not. As a result, C++ function names aremangledto get additonal information in the symbol table such as the number and type of each function parameter. So, C code c...
(Non-static member functions only) The ref-qualifier, which specifies to the compiler which overload of a function to choose when the implicit object parameter (*this) is an rvalue reference vs. an lvalue reference. For more information, seeFunction Overloading. ...
Since a function call can only resolve to one of them, the compiler has to determine which overloaded function is the best match. The process of matching function calls to a specific overloaded function is called overload resolution. In simple cases where the type of the function arguments and...

In Microsoft C++, global static objects are also initialized before entry to main. Several restrictions apply to the main function that don't apply to any other C++ functions. The main function:Can't be overloaded (see Function overloading). Can't be declared as inline. Can't be declared...
Other programming languages, such as the C++ programming language, do support function overloading. Within a given scope, there may be many distinct functions all associated with the same function name. In a language that permits function overloading, the use of a function name in a particular...

3. Maintainability Overriding promotes a modular design by encapsulating various functionalities within distinct classes. This approach simplifies understanding, maintaining, updating and extending the code. 4. Design Patterns Overriding plays a key role in the Template Method pattern by defining the overall...
