Concatenation in Go

Concatenation involves joining two or more strings together. In Go, the simplest way to concatenate two or more strings is to use the + operator. Here are some examples:

package main
import "fmt"
func main() {

  first_name := "John"

  last_name := "Doe"

  

  // Concatenating two strings

  name := first_name + " " + last_name

  fmt.Println(name) // Output: John Doe

  

  // Concatenating multiple strings

  sentence := first_name + " " + last_name + " is a programmer."

  fmt.Println(sentence) // Output: John Doe is a programmer.

  

  // Concatenating string literals

  quote := "Knowledge is " + "power."

  fmt.Println(quote) // Output: Knowledge is power.

}

In the above example, we first declare two variables first_name and last_name with the values "John" and "Doe" respectively. We then use the + operator to concatenate them together to form the full name.

We can also concatenate multiple strings together by using the + operator between each string.

Finally, we can also concatenate string literals directly without the need for variables.
