How to get Last N Characters in String in Go - Step by Step Examples

How to get Last N Characters in String in Go ?

Answer

To get the last N characters of a given string in Go, you can use string slicing. The syntax to use string slicing on a string str is str[start:stop]. Since we need the last N characters, we can specify start=len(str)-N, and stop=default value of length of string.

✐ Examples

1 Last 5 Characters of "Hello World" String

In this example,

We create a string named str1 with a string value of "Hello World".
We then use string slicing with negative indices str1[len(str1)-5:] to get the last 5 characters.
Finally, we print the last 5 characters.

Go Program

package main
import "fmt"
func main() {
    str1 := "Hello World"
    last5Chars := str1[len(str1)-5:]
    fmt.Println("Last 5 characters of the string are:", last5Chars)
}

Output

Last 5 characters of the string are: World

2 Last 3 Characters of "apple" String

In this example,

We create a string named str2 with a string value of "apple".
We then use string slicing with negative indices str2[len(str2)-3:] to get the last 3 characters.
Finally, we print the last 3 characters.

Go Program

package main
import "fmt"
func main() {
    str2 := "apple"
    last3Chars := str2[len(str2)-3:]
    fmt.Println("Last 3 characters of the string are:", last3Chars)
}

Output

Last 3 characters of the string are: ple
