How to get Length of String in Go ?

Answer

To get the length of a given string in Go (Golang), you can use the len function.

✐ Examples

1 Length of "Hello World" String

In this example,

We create a variable named str1 with a string value of "Hello World".
We then use the len function to get the length of the string and store the returned value in the variable length1.
The len function returns the length of the string.
Finally, we print the value in length1 to the console using fmt.Println.

Go Program

// Length of "Hello World" String
package main

import (
	"fmt"
)

func main() {
	str1 := "Hello World"
	length1 := len(str1)
	fmt.Println("Length of given string is:", length1)
}

Output

Length of given string is: 11

2 Length of "apple" String

In this example,

We create a variable named str2 with a string value of "apple".
We then use the len function to get the length of the string and store the returned value in the variable length2.
The len function returns the length of the string.
Finally, we print the value in length2 to the console using fmt.Println.

Go Program

// Length of "apple" String
package main

import (
	"fmt"
)

func main() {
	str2 := "apple"
	length2 := len(str2)
	fmt.Println("Length of given string is:", length2)
}

Output

Length of given string is: 5
