This is the first time I have heard of this function, this is the same as python’s args for unknown number of positional arguments in a function.
package main
import "fmt"
func main() {
total1 := sum(1,2,3)
nums := []int{10, 12, 13, 14}
/*
the nums... will list down the elements of a slice which is the same
as this:
for _, v := nums {
fmt.Println(v)
}
*/
total2 := sum(nums...)
fmt.Println("First total: ", total1)
fmt.Println("Second total by adding elements in slice: ", total2)
}
// variadic functions to take in unknown number of n.
// This is the same as the python args for positional arguments.
func sum(n ...int) int {
total := 0
for _, v := range n {
total += v
}
return total
}
