经过验证,go语言结构体作为函数参数,采用的是值传递.所以对于大型结构体传参,考虑到值传递的性能损耗,最好能采用指针传递. 验证代码: package main import ( "fmt" ) type st struct { id int name string } func main() { d := st{1, "Jo"} fmt.Println(d, "值传递前") fValue(d) fmt.Println(d, "值传递后…
以pass-by-reference-to-const 替换pass-by-value 考虑以下class继承体系 class Person { public: Person(); // parameters omitted for simplicity virtual ~Person(); // see Item 7 for why this is virtual ... private: std::string name; std::string address; }; class Stud…
