How can I print every second character in a string? Example:

Hello, my name is Jack!

There must be something like this (maybe a mistake): el,maeiak

    As usual: go through a cycle of letters and type every second character. - Enikeyshchik

I wondered if the string was iterable in Go and I wrote the following code:

 package main import "fmt" func main() { src := "Hello, my name is Jack!" for i, ch := range src { if i % 2 == 0 { fmt.Printf("%c", ch) } } }

I got the following conclusion:

 Hlo ynm sJc!

    It is displayed starting from the first character (index 0). To output from the second, you need to check for i% 2 == 1. - Enikeyshchik
