Function Overloading (achieved at compile time) It provides multiple definitions of the function by changing signature i.e changing number of parameters, change datatype of parameters, return type doesn’t play anyrole. Article Tags : C++. Nonetheless, you can always get a C/C++ compiler and exploit the function overloading whilst programming in straight C! This feature is present in most of the Object Oriented Languages such as C++ and Java. Overloading saves you from having to use names such as print_string or print_double. This is typically done by "mangling" the name of a function, and thus including the types of its arguments in the symbol definition. In short the return type of a function How to perform method overloading in Java? At compile time, the compiler chooses which overload to use based on the type of arguments passed in by the caller.
