Today, I will talk to you about the solution to the small pit of golang pointers, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

Record a small problem and go directly to the code.

Type hello struct {world string} f: = func (test * hello) {fmt.Printf ("% p\ n") Test) / / 0xc000012ba0 test = nil} test: & hello {world: "world"} f (test) fmt.Println (test) / & {world} fmt.Printf ("% p\ n", test) / / 0xc000012ba0

This means that the function always passes a value, and the value of the pointer is the address of the pointer.
