Write short philosophical answer

Experience with dangling refereces or memory leaks. If you have experience with a language like C, C++, or Pascal, in which dynamically allocated space must be manually reclaimed, describe your experience with dangling references or memory leaks. How often do these bugs arise? How do you find them? How much effort does it take? Learn about open source or commercial tools for finding storage bugs (Valgrind is a popular open source example). Do such tools weaken the argument for automatic garbage collection
