I didn't do anything, neither did the plan. Roar ~Saturday to see "21-Day learning Linux_c Programming" NOTE:All of a sudden there was no confidence in the book. At first, the following complaints arose:1. When creating the Vim launcher, type to

#include "stdafx.h" int _tmain (int argc, _tchar* argv[]) {/////////////////////////////////////////////////////////// Pointer constants: Data type * Const P//1. The//2 can only be assigned once at initialization time. You can modify the point of

Article 4: Determine that an object has been initialized before it is usedOneVariables may or may not be initialized under different circumstances.Note the difference between initialization and assignment.1. Implicit initialization does not occur in

Clause 11:1, the assignment operator returns a &, because Stl,string is doing this, unless you have good reasons not to do so.2, the method of handling self-assignment----(1), do not delete their data when the object data is not successful, to avoid

The idea of managing resources with objects is often referred to as "the opportunity for resource acquisition is the time of initialization" (RAII)Auto_ptr is automatically deleted when it is destroyed, so be careful not to let multiple auto_ptr

Article 17: Place the new object into a smart pointer with a separate statement.1, the Newed object is placed into the smart pointer in a separate statement, if not done, once the exception is thrown, it is possible to cause imperceptible resource

Recently in the interview to find a job, the interview encountered this problem has been many times, always want to know, take advantage of this opportunity to comb ah.When referring to a delegate, most people first impressions are the equivalent of
