What is function overloading and operator overloading?
✍: Guest
Function overloading: C++ enables several functions of the same name to be defined, as long as
these functions have different sets of parameters (at least as far as their types are concerned). This
capability is called function overloading. When an overloaded function is called, the C++ compiler
selects the proper function by examining the number, types and order of the arguments in the call.
Function overloading is commonly used to create several functions of the same name that perform
similar tasks but on different data types.
Operator overloading allows existing C++ operators to be redefined so that they work on objects
of user-defined classes. Overloaded operators are syntactic sugar for
equivalent function calls. They form a pleasant facade that doesn't add anything fundamental to the
language (but they can improve understandability and reduce
maintenance costs).
