Example
A variadic function can be called with any number of trailing arguments. Those elements are stored in a slice.
package main
import "fmt"
func variadic(strs ...string) {
// strs is a slice of string
for i, str := range strs {
fmt.Printf("%d: %s\n", i, str)
}
}
func main() {
variadic("Hello", "Goodbye")
variadic("Str1", "Str2", "Str3")
}
You can also give a slice to a variadic function, with ...:
func main() {
strs := []string {"Str1", "Str2", "Str3"}
variadic(strs...)
}
