The Constructor/Destructor model
One method of resource management is exemplified by the C++ concept
of objects having a constructor and destructor. A method adopted by
many (but not all) C++ programmers is to make the destructor responsible
for cleanup of all resources allocated by the object. This approach
works well provided all dynamic resources are clearly made the
responsibility of an object. But, as with the simple C approach, it
requires a good deal of care and attention to detail, for example
where resources are conditionally allocated, or shared between
many different objects, and is vulnerable to programming bugs.
