Go Data Type Strings

Introduction

Go string literals can be created using double quotes "Hello, World" or backticks `Hello, World`.

The double-quoted strings cannot contain newlines and they allow special escape sequences.

For example, \n gets replaced with a newline and \t gets replaced with a tab character.

The following are some common operations on strings: 

len("Hello, World")

Finds the length of a string 

"Hello, World"[1]

Accesses a particular character in the string, in this case, the second character. 

"Hello, " + World"

Concatenates two strings together 

package main//from ww w  .ja va 2 s. c  om

import "fmt" 

func main() { 
    fmt.Println(len("Hello, World")) 
    fmt.Println("Hello, World"[1]) 
    fmt.Println("Hello, " + "World") 
}

To convert a string to a slice of bytes (and vice versa), do this: 

arr  := []byte("test") 
str  := string([]byte{'t','e','s','t'})
