The C++ language allows the programmer to specify more than one definition for a function name or operator. It is one of the many useful features that object-oriented languages provide, which increases the power and flexibility of C++. In this tutorial, you will learn about types of overloading and how to use them in C++ programs.
What is Overloading?
Overloading is a technique of using a single identifier to define different methods of a class that differs in their input and output parameters. Overloading is generally used when a program block conceptually executes the same task but is slightly distinct in a set of parameters.
Overloading is a concept used to avoid redundant code where the same method name or operator is used multiple times but with a different set of parameters or number of operands. The actual method that gets called during runtime is resolved at compile time, thus avoiding runtime errors. Overloading provides code clarity, reduces complexity, and increases the runtime presentation of code.
