Solution Review: Variable Number of Arguments

This lesson discusses the solution to the challenge given in the previous lesson.

We'll cover the following...
Go (1.6.2)
package main
import "fmt"
func main() {
	// function calls for multiple arg.
	fmt.Println(sumInts())
	fmt.Println(sumInts(2, 3))	
	fmt.Println(sumInts(0, 1, 2, 3, 4, 5, 6, 7, 8, 9))
}
func sumInts(list ...int) (sum int){	// function to calculate sum of variable arg.
	for _, v := range list {
		sum = sum+v
	}
    return
}

In the code above, at line 11 there is a function header: sumInts(list ...int)(sum int) which means that sumInts takes ...
