Finding the length of a string in Golang

Problem Solution:

In this program, we will get the length of the specified string using the len() function and print the result on the console screen.

Program/Source Code:

The source code to get the length of the specified string is given below. The given program is compiled and executed successfully.

Golang code to find the length of the specified string

// Golang program to get the length of the
// specified string.

package main

import "fmt"

func main() {
	var str string = "Hello World"
	var length int = 0

	length = len(str)

	fmt.Println("Length of string is: ", length)
}

Output:

Length of string is:  11

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created two variables str and length, which are initialized with "Hello World", 0 respectively. Then we got the length of the string using the len() function and printed the result on the console screen.
