Getting characters from a string using the index in Golang

Problem Solution:

In this program, we will create a string and then access characters one by one using the index just like an array.

Program/Source Code:

The source code to get characters from a string using the index is given below. The given program is compiled and executed successfully.

Golang code to get characters from a string using the index

// Golang program to get character
// from string using index

package main

import "fmt"

func main() {
	str := "Hello World"

	for i := 0; i < len(str); i++ {
		fmt.Printf("%c", str[i])
	}
}

Output:

Hello World

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 a string variable str, which is initialized with "Hello World". After that, we accessed the character from the string one by one using the index just like an array and print them on the console screen.
