If the answer is yes, then by all means catch it, deal with it and allow construction to continue. If the answer […]

You’ve debugged the code and discovered it happens when your class goes out of scope and needs to throw an exception from the destructor. Tested in isolation, […]
In C++ all arguments are passed to functions by value. In other words, a copy of the value is taken and that is what the function has to work with. If you want to modify the original value you must either pass a pointer or reference to the original value you wish to modify. Of […]
C is Not C++!!! A superset of nothing useful I often hear those who really should know better giving the advice that before you learn to code in C++ you should first learn to code in C. At face value this would seem like reasonable advice; after all C++ is a superset of C and […]
