• Types of variable

1. Int
2. Float32
3. String
4. Bool

 In Go language variables are defined in two different ways:

1. Using var keyword

 Syntax:

Var variable_name type =value

2. Using the short variable declaration

 Syntax:

              Variable_name :=value

1. Simple variable deceleration Go Lang program.

   package main
   import "fmt"
   
   func main() {
       var a string = "Prwatech"
       var b int = 323
       var c bool = true
   
       fmt.Println(a)
       fmt.Println(b)
       fmt.Println(c)
   }
   

   Output :

2. Program to illustrate local variable and global variable.

   package main
   import "fmt"
   //global -- (Pascal Case)
   var Val2 int = 50
   //Package Level --(Camel Case)
   var myValue int = 70
   
   func main() {
       println("Global Variable :", Val2)
       println("Pakage Variable :", myValue)
   
       var a int //variable declearation    
   Output :
   

3. Program to illustrate variable using function.

   package main
   import "fmt"
   
   var x = 15
   
   func Prwa() {
       var x = 6
       fmt.Println("in Prwa :", x)
   }
   func main() {
       Prwa()
       fmt.Println("in Main :", x)
   
   }
   

   Output :
