Languages **with** Variadic Functions include c, go, php

### Example from c:

double average(int count, ...) { // }

### Example from go:

// This variadic function takes an arbitrary number of ints as arguments. func sum(nums ...int) { fmt.Print("The sum of ", nums) // Also a variadic function. total := 0 for _, num := range nums { total += num } fmt.Println(" is", total) // Also a variadic function. }

### Example from php:

function sum(...$nums) { return array_sum($nums); } echo sum(1, 2, 3); // 6
