在 C++ 中,变量的声明不必像 C 和 Fortran 一样放在程序最前方,可以在变量使用前声明,增加程序可读性。

C++ 中有布尔类型变量,关键字为 bool。

C++ 中标准库内 numeric_limits 模板函数可以返回不同类型变量的最大值与最小值。

C++ 内标示符要求由字符、数字与下划线组成,标示符必须以字符或下划线开头,字符大小写是区分的。

数据库系统概念笔记-引言

 数据库管理系统(DBMS)由一个互相关联的数据的集合和一组用以访问这些数据的程序组成.这个数据集合通常称作数据库,其中包含了关于某个企业的信息.   DBMS的主要目标是要提供一种可以方便.高效地存取数据库信息的途径. 1.1 数据视图 1.1.1 数据抽象 一个可用的系统必须能高效地检索数据.这种高效性的需求促使设计者在数据库中使用了复杂的数据结构来表示数据,但是,有很多数据库用户不懂这些.为此,数据库的系统开发人员通过如下几个层次上的抽象来对用户屏蔽复杂性,以简化用户与系统的交互: 物理层
