Attribute declaration (C++11) Empty declaration. [edit] An enumeration is a distinct type whose value is restricted to a range of values (see below for details), which may include several explicitly named constants (" enumerators "). The values of the constants are values of an integral type known as the underlying type of the enumeration.But you can get name collisions if other classes define a constant of the same name, which is arguably not a bad thing as it may be a good indication of an area that could be refactored. Recently, I decided that it would be better to declare class specific constants inside of the class definition itself: //.h. class MyClass {.C++ 类定义. 定义一个类需要使用关键字 class ，然后指定类的名称，并类的主体是包含在一对花括号中，主体包含类的成员变量和成员函数。. 定义一个类，本质上是定义一个数据类型的蓝图，它定义了类的对象包括了什么，以及可以在这个对象上执行哪些操作。I.e. you can use it as a compile time constant or in any circumstance where an rvalue suffices: int x = 1 + type::constant;, but not where an lvalue is required: int const & k = type::constant;. @Nawaz: For integral constants, it is usually better to provide the value in the declaration, instead of the definition.Please note: c++ newbie.

You can earn a C average by getting C's in every class, or offsetting a lower grade with more than one C+'s or B's. For example, if you got an C, C, C-, B- and B, the B- and B will cancel out the C- and you will have a 2.28 GPA (C). In summary, you need to earn more B's or C+'s than C-'s. Every variable in C++ has two features: type and storage class. Type specifies the type of data that can be stored in a variable. For example: int, float, char etc. And, storage class controls two different properties of a variable: lifetime (determines how long a variable can exist) and scope (determines which part of the program can access it).Initialising Class Object within another Class header file. ...
