Original: http://www.cnblogs.com/GavinDai/archive/2011/10/24/2222735.htmlWe are in the program design, always use the definition of variables and the declaration of variables, but sometimes we are not very clear about the concept, know how it is used, but do not know how a thing, the following I will simply introduce their differences are as follows: (Hope my guidance to you benefit)There are two scenarios for declaring a variable:1, one is the need t

Class Definition details in C ++ Member variables Each class can have no members or multiple members. The members can be data, functions, or type aliases. A class can contain several public, private, and protected parts. Members defined in the public part can be accessed by all code using this type; Members defined in the private part can be accessed by other class members. Protected can be accessed by the quilt class. Constructor A function that has

variable declarations and variable definitions Variable definitions: Used to allocate storage space for a variable, and to specify an initial value for a variable. In a program, a variable has and has only one definition. Variable declaration: Used to indicate the type and name of a variable to a program. A definition is also a declaration, an extern declaration is not a

1 OverviewUsed preprocessing commands starting. For example, include the command # include and macro definition command # define. In the source program, these commands are placed outside the function, and are generally placed before the source file. They are called preprocessing. Preprocessing refers to the work done before the first scanning (lexical scanning and syntax analysis) of compilation. Preprocessing is an important function of C language, w

C ++ declaration and definitionC ++ declaration and definition The Declaration is to introduce a name into the program. The definition provides a unique description of an object in the program. Declarations and definitions sometimes exist at the same time. Such as int; Extern int B = 1; It is declared only when there is no initialization in extern. In other cases, it is both a
