Paraméterlista

Paraméterlista, often translated as parameter list or argument list, refers to the collection of values or variables passed to a function or method when it is called. In programming, functions are designed to perform specific tasks, and they often require input data to do so. This input data is provided through the parameter list.

The parameters within a parameter list are typically defined in the function's declaration or definition. Each parameter has a name and often a data type, specifying the kind of information it expects. When a function is invoked, the actual values provided are called arguments. These arguments are then assigned to the corresponding parameters within the function's scope.

The order and number of arguments in a function call must generally match the order and number of parameters defined in the function's signature. Mismatches can lead to errors. Some programming languages offer features like default parameter values, which allow a parameter to have a predefined value if no argument is provided during the function call. Others support variable-length parameter lists, enabling a function to accept an arbitrary number of arguments. Understanding parameter lists is fundamental to comprehending how functions receive and process data in software development.
