variadic

Documentation

Overview

variadic demonstrates variable length arguments to Go functions

• A variable length argument can be specified with "..." before the type
• Example: "numbers ...int"
• Inside the function, the type becomes a slice ([]numbers)

In addition, we can also pass a slice with "..." to expand it as a argument list while calling the function. Example: sumAll(numbers...)

• The fmt.Printf and other formatting functions are the great examples for variadic functions.
