Display the total number of objects. Is my program correct?
Code:#include<iostream> using namespace std; class Object { public: static int nb_of_objects; Object () { nb_of_objects++; } Object(const Object&){ cout << " Object: copy constructor " << endl; nb_of_objects++; } static void show(){ cout << "Number of objects created is:" << nb_of_objects << endl; } }; int Object::nb_of_objects = 0; int main(){ Object::nb_of_objects; Object o; Object o2 = o; o.show(); return 0; }
Looks good to me.
nb_of_objects could be made private, since you don't access it directly (you use the show function instead). Also, remove the line
in your main function. You have already provided a static member initializer for this data item, so you don't need to refer to it from main.Code:Object::nb_of_objects;
