How to convert a byte slice to a string using strconv.Itoa() in Golang?

In Golang, strconv.Itoa() is used to convert an integer to a string. If you want to convert a byte slice to a string using strconv.Itoa(), you first need to convert the byte slice to an integer and then convert the integer to a string.

Here's an example of how you can achieve it:

package main

import (
	"fmt"
	"strconv"
)

func main() {
	// Example byte slice
	b := []byte{49, 50, 51} // corresponds to "123" in ASCII

	// Convert byte slice to integer
	num, err := strconv.Atoi(string(b))
	if err != nil {
		fmt.Println("Failed to convert byte slice to integer:", err)
		return
	}

	// Convert integer to string using strconv.Itoa()
	str := strconv.Itoa(num)

	fmt.Println("Converted string:", str) // Output: 123
}

In the above code, strconv.Atoi() is used to convert the byte slice b to an integer num. Then, strconv.Itoa() is used to convert num back to a string str. Finally, str is printed, which will give you the expected result.
