funkcióváltozatosság

Funkcióváltozatosság, sometimes translated as function variation or functional polymorphism, is a concept in programming that describes the ability of a single function name to refer to different implementations based on the type or number of arguments it receives. This allows for more flexible and readable code by reducing the need for multiple function names that perform similar tasks.

In essence, a function can be overloaded, meaning that multiple functions can share the same name but have distinct parameter lists. When the function is called, the compiler or interpreter determines which specific implementation to execute based on the arguments provided in the call. This mechanism is a form of static polymorphism if resolved at compile time or dynamic polymorphism if resolved at runtime.

The primary benefit of funkcióváltozatosság is improved code organization and a more intuitive API. Instead of calling `addInts(a, b)` and `addFloats(x, y)`, a programmer can simply call `add(a, b)` and `add(x, y)`, with the correct addition operation being invoked automatically. This can lead to cleaner and more maintainable software.

While the exact implementation and availability of funkcióváltozatosság vary across programming languages, it is a common feature in many modern languages, including C++, Java, and C#. Some languages achieve this through explicit function overloading, while others might use features like default arguments or variadic functions to achieve similar effects. Understanding funkcióváltozatosság is key to writing efficient and well-structured code in these environments.
