Chapter 17: Making Constructive Arguments 237class Student{public:Student (int id, int age) : sAge(age), sId(id){}const int sId;const int sAge;};In this example, sId is constructed before sAge, even though sId appearssecond in the constructor’s initialization list. The only time you might detecta difference in the construction order is when both data members are aninstance of a class that has a constructor that has some mutual side effect.Destructors destruct in the reverseorder of the constructorsFinally, no matter in what order the constructors kick off, you can be assuredthat the destructors are invoked in the reverse order. (It’s nice to know thatat least one rule in C++ has no ifs, ands, or buts.)
