When the variable is referenced once, the refcount will be +1. When you unset it, the value will be reduced by 1 until it reaches 0 and it will be deleted from the memory.2. When you de

2.1. Variable parameter functionsVariable parameters means that the number of parameters can be any numberThe variable parameter must be at the end of the parameter list. Add three dots between the parameter name and the type to indicate the variable parameter functionWhen declaring a function, use the variable parameter as a slice in the function bodypackage main import "fmt" func demo(name string, hover ... string) { fmt.Println(name,"My hobby is") for i,n := range hover{ fmt.Println(i,n) } }
