Solution Review: Variable Number of Arguments

Explore how to define and use functions in Go that accept a variable number of integer arguments. Understand the syntax and logic to iterate over these arguments and return their sum. This lesson helps you master flexible function calls and prepares you for advanced Go function concepts.

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
}
