Variables

Referencing in Go

Referencing is used to get the memory address of any variable.

Syntax

&variableName //can be used for any variable
pointerVariable := &variableName //creating a pointer variable using the address

Notes

Both pointers and standard variables can be referenced.

Example

package main

import "fmt"

func main() {
    animal := "cat"
    var pet *string
    pet = &animal //address of animal now in the pet pointer
    fmt.Println("My pet: ", *pet) //will print cat, value assigned to animal
    *pet = "dog" //assigning a new value to animal's address location, changing its value
    fmt.Println("Type of pet animal: ", animal)
}
