Function overloading is a powerful feature in C++ that allows multiple functions with the same name to exist in the same scope, provided their parameter lists are different. This feature is a part of polymorphism<\/strong> in Object-Oriented Programming (OOP) and allows developers to implement functions that perform similar tasks but operate on different types or numbers of inputs.<\/p>\n\n\n\n Function overloading occurs when:<\/p>\n\n\n\n Below is an example demonstrating function overloading using a Function overloading in C++ is a key feature of polymorphism that enhances code reusability and readability. By allowing functions with the same name to handle different types and numbers of parameters, developers can write cleaner and more organized code. In the provided example, the overloaded Introduction: Function overloading is a powerful feature in C++ that allows multiple functions with the same name to exist in the same scope, provided their parameter lists are different. This feature is a part of polymorphism in Object-Oriented Programming (OOP) and allows developers to implement functions that perform similar tasks but operate on different types or numbers of inputs.
