How the Go language implements polymorphic functions similar to C + +

This is a created article in which the information may have evolved or changed.

As a rising star in programming language, go language is a good development language, while absorbing and losing individuality, paying attention to the efficiency of the operation while emphasizing the development. In the go language, there is no concept of class, but you can still use Struct+interface to implement the function of the class, and this simple example demonstrates how to use go to simulate polymorphic behavior in C + +.

Package Mainimport "OS" import "FMT" type Human interface {    SayHello ()}type Chinese struct {    name String}type Engli SH struct {    name String}func (c *chinese) SayHello () {    fmt. Println (c.name, "Say Hello, World")}func (e *english) SayHello () {    fmt. Println (e.name, "Says:hello,world")}func Main () {    fmt. Println (len (OS). Args)        c: = chinese{"doggy Person"}    e: = english{"Jorn"}    m: = map[int]human{}        m[0] = &c    m[1] = &e< C12/>for i:=0;i<2;i++ {        M[i].sayhello ()    }}

From the above example, it is very simple to implement polymorphism in go similar to C + +, as long as the same interface can be implemented.
