As an example you could check if a file exists before you try to open it, however it could potentially be deleted in that fraction of a second between you checking and actually opening it.This is a good point.

I have 1 error trapping in my game, and thats to check if string array is dimmed or not.īut if I where to create a utility program, using a lot of external activex etc. I do extensive testing to try to catch all errors and fix those so that its not needed. I work on "no-error trapping" as much possible. So work with On Error -"- and create a robust code that can deal with errors,Īnd instead of crashes, you simply inform the user that "something happened" and if possible resume. Many "experts" do this already, that have functions that are just there for errors. Or you add error trapping where you "think" could cause errors. The section contains C++ MCQs on different aspects of a container which includes creation and design of new containers, vectors and sequences, types of inheritance and various class hierarchies, sequences like seq_con array class, seq_con vector class, stl – pair and heap, vtable, vptr, generators, array type manipulations, tuples, complex library, valarray, bitset and class relationships.Or you create a waterproof code where u don't need error trapping C++ MCQ on Class Hierarchies, Library & Containers C++ Template Arguments for Policy UsageĦ.C++ Class Hierarchies & Abstract Classes.The section also has error and exception handling, different types of exceptions and their resource management. The section contains C++ Programming questions and answers on different types of classes like abstract, derived and their hierarchies, different types of templates like simple string and function and their derivation and specialization.
