A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

In Visual Studio 2019, under /std:c++latest (or /std:c++20 in Visual Studio 2019 version 16.11 and later), a class with any user-declared constructor (for example, including a constructor declared = default or = delete) isn't an aggregate. Previously, only user-provided constructors would...

上面的分析也是基于VS搞的,不过准确来说函数多个参数的计算顺序是未定义的(the order of evaluation of function arguments are undefined)。笔试题目的运行结果随不同的编译器而异。 这里还有一个 i++ 的典型应用案例。 代码语言:javascript 代码运行次数:0 ...

(Simple) Every constructor should initialize every member variable (either explicitly, via a delegating ctor call or via default construction). (简单)所有的构造函数都应该初始化每个成员(可以明确地通过委托构造函数或默认构造函数) (Simple) Default arguments to constructors suggest an in-class initializer...
