1. // Variables
   
2. package main
   
3. 
   
4. import (
   
5.     "fmt"
   
6. )
   
7. 
   
8. func main() {
   
9.     var a string = "initial"
   
10.     fmt.Println(a)
    
11.     //You can declare multiple variables at once.
    
12.     var b, c int = 1, 2
    
13.     fmt.Println(b, c)
    
14.     //Go will infer the type of initialized variables.
    
15.     var d = true
    
16.     fmt.Println(d)
    
17.     //Variables declared without a corresponding initialization are zero-valued. For example, the zero value for an int is 0.
    
18.     var e int
    
19.     fmt.Println(e)
    
20.     //The := syntax is shorthand for declaring and initializing a variable, e.g. for var f string = "short" in this case.
    
21.     f := "short"
    
22.     fmt.Println(f)
    
23. }
