4.7 语言特性
温度和字典程序用到了本章介绍的大部分语言特性：循环（for语句和while语句）、选择语句（if语句）、简单的算术运算（++和+=操作）、比较和逻辑运算（==，！=和||）、变量和函数（例如main（）、sort（）和size（）等）。此外，还用到了标准库提供的功能，例如vector（一种数据元素的容器）、cout（标准输出流）和sort（一种排序算法）。
仔细回想一下，你会发现我们已经用到了很多语言特性。每一种语言特性都表示了一种基本思想，将许多种语言特性结合起来，我们就能写出有用的程序了。记住：计算机不是一种只能完成固定功能的设备，它可以完成我们能想象到的任何计算任务。而且，通过计算机与其他设备的结合，理论上我们可以用它来完成任何任务。
