| Lecture 4 - Slide 12 : 40 |
An example where it is necessary to program a destructor
For sake of the example we introduce a dynamically allocated representation of points
| Class Point - representated as a dynamically allocated array of two doubles . |
| Implementation of class point - with an insufficient destructor . |
| A sample program with memory leaks. |
| Class Point - with a pointer representation - same as before. |
| Implementation of class point - now with a destructor that deallocates the Point representation. |
| A sample program - now without memory leaks. |
 | Output from the program. |
 | Point destruction - now with a problematic point copy constructor |
If an object o allocates resources when constructed - or during its life time - o's destructor is responsible for relinquishing these resources when o is deleted or goes out of scope
If o does not allocate such resources, its destructor is typcially not programmed
