Explain the default constructor and destructor, C/C++ Programming

Assignment Help:

The default Constructor and Destructor

If you fail to write a constructor and destructor function,  the compiler automatically supplies them for you. These functions have public access and essentially do nothing useful. If you were to write these functions yourselves, this would look like:

                class employee

                 {

                public :

                                employee()

                                                 {

                                                 }

 

                                ~employee();

                                 {

                                 }

    };
