Example
Methods in Go are just like functions, except they have receiver.
Usually receiver is some kind of struct or type.
package main
import (
"fmt"
)
type Employee struct {
Name string
Age int
Rank int
}
func (empl *Employee) Promote() {
empl.Rank++
}
func main() {
Bob := new(Employee)
Bob.Rank = 1
fmt.Println("Bobs rank now is: ", Bob.Rank)
fmt.Println("Lets promote Bob!")
Bob.Promote()
fmt.Println("Now Bobs rank is: ", Bob.Rank)
}
Output:
Bobs rank now is: 1
Lets promote Bob!
Now Bobs rank is: 2
