A variable argument function (variadic function) accepts an undefined number of parameters. Formatted output functions are known as variadic functions in several computer languages. The STDARG macros va arg, va end, and va start provide access to the variable argument list macros va arg, va end, and va start.
In order to establish the function, there are three associated elements. Declaration of a function. call to a function Definition of the function.
Another approach to send parameters to a function is to use the 'arbitrary argument' list. These parameters will be wrapped in a tuple in the function body, which can be constructed using the *args construct. You can specify a number of arguments or none before this variable.
No-argument and no-return-value functions. Functions with no arguments and return values are classified as category 2. Functions with arguments but no return values fall into category 3. Functions with arguments and return values fall within category 4.
A variable-length argument is a feature that allows any number of arguments to be passed to a function. There are some instances when a function must deal with a variable number of arguments, such as: The total of the numbers presented. The bare minimum of the provided numbers, plus many more.
