Program Plan- To define two classes: classItem and classItemGroup. Create objects of classItem in classItemGroup which could call the constructors desired. Using an exception handler in test program, check result for a specific value (in this program value is 2). When this value is validated, the program throws an exception and destructors are called only for those constructors which were called before the exception. Summary Introduction- The program to demonstrate that destructors are called only for the object constructed before the exception. Program Description- The program contains 5 files: classItem.h, classItem.cpp, classItemGroup.h, classItemGroup.cpp and testItem.cpp.
