NULL is 0(zero) i.e. integer constant zero with C-style typecast to void*, while nullptr is prvalue of type nullptr_t which is integer literal evaluates to zero. For those of you who believe that NULL is same i.e. (void*)0 in C & C++. I wo...
One of the reasons to use nullptr in c++11 ishttps://www.zhihu.com/question/55936870. A simple demo of the comparison between nullptr, 0, and (void*)0. // nullptr#include<iostream>usingnamespacestd;intmain(){void* p1 =0;intp2 =0;// if(p1 == p2)// cout << "1" << endl;if...
這表示欄位可以有值,或是等於 nullptr。 更豐富的例外狀況資訊。 C++/CX 支援新 Windows 錯誤模型,能夠跨應用程式二進位介面 (ABI) 擷取及散佈豐富的例外狀況資訊,包括呼叫堆疊和自訂訊息字串。 Object::ToString() 現在是虛擬的。 您現在可以覆寫使用者定義的 Windows 執行階段 ref 類型中的 ToString。 支援已...
What is the maximum length of a HiLog record? Is it configurable? Why is private displayed in HiLog information when the format parameter %d or %s is specified? What should I do if the hilog.debug log cannot be printed? How do I control the log output level based on the environme...

The Microsoft-specific __nullptr keyword has the same meaning as nullptr, but it applies to native code only. If you compile native C/C++ code by using the/clrcompiler option, the compiler cannot determine whether the nullptr keyword is a native or a managed term. To make your intention cl...

Use SetDllDirectory() again to restore the previous value. Keep the changes to the DLL search path in effect for as short of a code-scope as possible Never call SetDllDirectory(nullptr) as it adds the current working directory to the search path and causes a security vulnerability. For...
In C++11, if the compiler is able to determine the type of a variable from its initialization, you don't need to provide the type. For example, you can write code such asint x = 3; auto y = x; and the compiler will deduce that y is an int. This, of course, isn't a ...
