How to concatenate two strings in Golang?

In Golang, you can concatenate two strings using the + operator or the fmt.Sprintf function. Here's an example using both methods:

Using the + operator:

package main

import "fmt"

func main() {
  str1 := "Hello"
  str2 := "world"
  result := str1 + " " + str2
  fmt.Println(result)
}

Output:

Hello world

Using fmt.Sprintf:

package main

import "fmt"

func main() {
  str1 := "Hello"
  str2 := "world"
  result := fmt.Sprintf("%s %s", str1, str2)
  fmt.Println(result)
}

Output:

Hello world

Both approaches can be used to concatenate two or more string variables or constants.
