How to get Substring from Specific Index to End in Go - Step by Step Examples

How to get Substring from Specific Index to End in Go ?

Answer

To get a substring from a specific index to the end of the string in Go, you can use string slicing. If str is the string, and we need the substring after an index i, then the syntax of the expression is str[i:]. This expression returns the substring from specified index till the ending of the string.

✐ Examples

1 Substring from Index 5 to End in "Hello World"

In this example,

We create a variable named str with a value of "Hello World".
We use slicing with str[5:] to get the substring from index 5 to the end of the string.
Finally, we print the extracted substring.

Go Program

package main

import "fmt"

func main() {
	str := "Hello World"
	substring := str[5:]
	fmt.Println("Substring from index 5 to end:", substring)
}

Output

Substring from index 5 to end:  World

2 Substring from Index 3 to End in "Go Programming"

In this example,

We create a variable named text with a value of "Go Programming".
We use slicing with text[3:] to get the substring from index 3 to the end of the string.
Finally, we print the extracted substring.

Go Program

package main

import "fmt"

func main() {
	text := "Go Programming"
	substring := text[3:]
	fmt.Println("Substring from index 3 to end:", substring)
}

Output

Substring from index 3 to end: Programming
