Optional parameters allow functions to be called with fewer arguments than they are defined to accept, providing default values for missing arguments. This feature enhances flexibility and code readability by reducing the need for multiple function overloads or complex conditional logic to handle different argument scenarios.
Variadic functions are functions that accept a variable number of arguments, allowing for greater flexibility in how they are called. They are commonly used in programming languages like C, C++, and Python to handle operations such as logging or formatting where the number of inputs can vary.
A function signature defines the input and output interface of a function, specifying the number and types of its parameters and the type of its return value. It serves as a contract that ensures consistent usage and understanding of the function's behavior in a codebase.
Named arguments allow you to specify the name of the parameters when calling a function, making the code more readable and reducing the risk of errors from incorrect argument order. They are particularly useful in functions with multiple optional parameters or when dealing with functions that have parameters with default values.
Default arguments in programming allow functions to be called with fewer arguments than defined by providing default values for some parameters. This feature enhances flexibility and code readability by enabling optional parameters without overloading functions.
