How to use pointers

Pointer usage process:

Define pointer variables.

Assign a value to the pointer variable.

Access the value in the pointer variable that points to the address.

Precede the pointer type with a * (prefix) to get what the pointer points to.

Example

Package main

Import "fmt"

Func main () {

Var an int= 20 / * declare the actual variable * /

Var ip * int / * declare pointer variable * /

Ip = & a / * Storage address of pointer variable * /

Fmt.Printf (the address of "a variable is:% x\ n", & a)

/ * Storage address of pointer variable * /

Fmt.Printf ("pointer address stored by the ip variable:% x\ n", ip)

/ * use pointers to access values * /

Fmt.Printf ("* ip variable value:% d\ n", * ip)

}

The output of the above example is as follows:
