noreturn.c: In function `test': noreturn.c:12: warning: control reaches end of non-void function 警告信息也很好理解,因为你定义了一个有返回值的函数test却有可能没有返回值,程序当然不知道怎么办了!加上__attribute__((noreturn))则可以很好的处理类似这种问题。

An instance constructor is a method whose task is to create an instance of a class. A constructor is a member function whose task is to initialize the objects of its class, in other words it is a method of a class that executes when the class's objects are created. It is called a ...

well-defined in the event of an exception that is thrown at any point during the function. What does this really mean? Well, let's take a rather contrived (and trite) example. This class wraps an array of some user-specified type. It has two data members: a pointer to the array and...
若不对类类型(struct、class 或 union)提供任何用户声明的构造函数,则编译器将始终声明一个作为其类的 inline public 成员的默认构造函数。 当存在用户声明的构造函数时,用户仍可以关键词 default 强制编译器自动生成原本隐式声明的默认构造函数。 上面这段话告诉我们:只有在没有任何用户声明的构造函数的情况下,编译...
C++11, common initializations in multiple constructors of the same class could not be concentrated in one place in a robust, maintainable manner. To partially alleviate this problem in the existing C++ programs, you could useassignmentinstead of initialization or add a common initialization function....
