Variables

Go variables hold typed values that can feed later expressions.

variables.go

package main

import "fmt"

func main() {
	var unitPrice = 
	quantity := 3
	total := unitPrice * quantity

	fmt.Println("unit=", unitPrice)
	fmt.Println("total=", total)
}

package main

import "fmt"

func main() {
	var unitPrice = 
	quantity := 3
	total := unitPrice * quantity

	fmt.Println("unit=", unitPrice)
	fmt.Println("total=", total)
}

package main

import "fmt"

func main() {
	var unitPrice = 
	quantity := 3
	total := unitPrice * quantity

	fmt.Println("unit=", unitPrice)
	fmt.Println("total=", total)
}

variable `var` declares a variable. Go infers the type from the value when no explicit type is written.
