type Employee struct {
name string
salary int
}
func (e *Employee) changeName(newName string) {
(*e).name = newName
}
func main() {
e := Employee{
name: "Ross Geller",
salary: 1200,
}
// e before name change
fmt.Println("e before name change =", e)
// create pointer to `e`
ep := &e
// change name
ep.changeName("Monica Geller")
// e after name change
fmt.Println("e after name change =", e)
}
为什么 要 ep := &e，而不是直接 e.changeName 来修改呢，结果不是都 一样吗
