Go Keywords

Last Updated : 03 Feb, 2020

Keywords or Reserved words are the words in a language that are used for some internal process or represent some predefined actions. These words are therefore not allowed to use as an identifier. Doing this will result in a compile-time error.

Example:

// Go program to illustrate the 
// use of keywords 
package main 
import "fmt"
  
// Here, package, import, func, 
// var are keywords 
func main() { 
  
// Here, a is a valid identifier 
var a = "GeeksforGeeks" 
  
fmt.Println(a) 
  
// Here, the default is an 
// illegal identifier and 
// compiler will throw an error 
// var default = "GFG" 
} 

Output:

GeeksforGeeks

There are total 25 keywords present in the Go language as follows:

break

case

chan

const

continue

default

defer

else

fallthrough

for

func

goto

import

interface

map

package

range

return

select

struct

switch

type

var

Example:

// Go program to illustrate  
// the use of keywords 
  
// Here package keyword is used to  
// include main package in the program 
package main 
  
// import keyword is used to  
// import "fmt" in your package 
import "fmt"
  
// func is used to 
// create function 
func main() { 
  
    // Here, var keyword is used  
    // to create variables 
    // Pname, Lname, and Cname  
    // are the valid identifiers 
    var Pname = "GeeksforGeeks" 
    var Lname = "Go Language" 
    var Cname = "Keywords"
      
    fmt.Printf("Portal name: %s", Pname) 
    fmt.Printf("\nLanguage name: %s", Lname) 
    fmt.Printf("\nChapter name: %s", Cname) 
  
} 

Output:

Portal name: GeeksforGeeks
Language name: Go Language
Chapter name: Keywords
