| Abstract: | First we introduce the features and classification of class constructors, and illustrate the constructing methods and call order of combined class object and derived class object constructors, then give the solution to pointer hung caused by operator new in class while using default copy constructor, finally introduce the functions of conversion constructor and the procedure of type conversion by using conversion constructor |
