Application
Create new folder named src. In src folder, create new file named main.go as below:
package main
import (
"fmt"
)
func main() {
fmt.Println("Demo 1")
Demo1()
fmt.Println("Demo 2")
Demo2()
fmt.Println("Demo 3")
Demo3()
}
func Demo1() {
var age = 20
var fullName = "abc"
var status = true
var price = 4.5
var key = 'B'
fmt.Println("age:", age)
fmt.Println("full name:", fullName)
fmt.Println("status:", status)
fmt.Println("price:", price)
fmt.Printf("key: %c and position in ASCII: %d\n", key, key)
}
func Demo2() {
var (
age = 20
fullName = "def"
status = false
price = 4.5
key = 'C'
)
fmt.Println("age:", age)
fmt.Println("full name:", fullName)
fmt.Println("status:", status)
fmt.Println("price:", price)
fmt.Printf("key: %c and position in ASCII: %d\n", key, key)
}
func Demo3() {
var a1, a2, a3 int = 20, -5, 7
fmt.Println("a1:", a1)
fmt.Println("a2:", a2)
fmt.Println("a3:", a3)
}
Output
Open Terminal windows in Visual Studio Code and run command line: go run main.go
Demo 1
age: 20
full name: abc
status: true
price: 4.5
key: B and position in ASCII: 66
Demo 2
age: 20
full name: def
status: false
price: 4.5
key: C and position in ASCII: 67
Demo 3
