将值赋给字符串解引用操作符

Question

我是新来的，请原谅我，如果这是一个常规问题，那么如何赋值给字符串解引用操作符在下面工作？

package main  

import "fmt" 

func main() { 
    course := "Docker Deep Dive" 
    changeCourse(&course) 
} 

func changeCourse(course *string) { 
    fmt.Println(course) // prints the memory address of course since it is a pointer 
    fmt.Println(*course) // prints the value since * is dereferenceing the pointer 

    // Issue 
    *course = "Docker Extended" // *course is a string, how does the assignment works here. 
    fmt.Println(*course) // prints "Docker Extended" 
} 

Answer 1

*（也称为间接运算符）是用来“解引用”指针变量，解引用指针让我们访问的价值指针指向。
在这种情况下：*course = "Docker Extended"基本上你在说的是编译器：在内存位置course指的是存储string“Docker Extended”。
