Pointers in Go

 Pointers in Go

Go supports pointers, which allow you to reference the memory address of a variable. You can declare a pointer using the * symbol, and you can access the value of the variable using the * operator.

var a int = 42

var b *int = &a // b is a pointer to a

fmt.Println(*b) // prints 42

*b = 10        // change the value of a through the pointer

fmt.Println(a) // prints 10
