Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.

A class is a data type, which defines a group of data objects. All data objects in the group must have the same list of properties. Functional methods are also provided and applicable to all data objects in the group. For example, "array" is a class. All data objects of the "array"...

But in Visual Studio 2015, the constructor and destructor are not called. The compiler gives a warning about this behavior change. Output Copy warning C4587: 'U::s': behavior change: constructor is no longer implicitly calledwarning C4588: 'U::s': behavior change: destructor is no longer...
Any deviation is flagged by FxCop as a violation of this code pattern. This is one area where C++ again has a bit of an edge on C#. The C++ compiler does much of the work of implementing IDisposable due to its destructor syntax. C# is a pure .NET language, so in many ways, has...
