How to Append a Character to end of a String in Go - Step by Step Examples

How to Append a Character to end of a String in Go ?

To append a character to the end of a string in Go, you can use string concatenation with the + operator or the += operator.

In this example,

We create a variable named str1 with a string value of "Hello World".
We then use string concatenation with the + operator to append the character '!' to str1.
Finally, we print the modified string to the console.

package main

import "fmt"

func main() {
    str1 := "Hello World"
    str1 += "!"
    fmt.Println(str1)
}

Hello World!

In this example,

We create a variable named str2 with a string value of "How are you".
We then use string concatenation with the += operator to append the character '?' to str2.
Finally, we print the modified string to the console.

package main

import "fmt"

func main() {
    str2 := "How are you"
    str2 += "?"
    fmt.Println(str2)
}

How are you?
