Variadic Functions

Variable arguments

Variadic functions accept any number of arguments. Use ... before the type to make the last parameter variadic:

func sum(nums ...int) int {
    total := 0
    for _, n := range nums {
        total += n
    }
    return total
}

Call it with any number of integers: sum( $1$ , $2$ , $3$ ) or sum( $1$ , $2$ , $3$ , $4$ , $5$ ). Inside the function, nums is a slice containing all the arguments passed.
