你所不知道的 set 容 器 by 小彭老师（ @archibate ） 课件 & 代码： https://github.com/parallel101/course 上期回顾： https://www.bilibili.com/video/BV1qF411T7sd 课程安排 1. vector 容器初体验 & 迭代器入门 (BV1qF411T7sd) 2. 你所不知道的 set 容器 & ，内存管理与对象生命周期 set 和 vector 的区别 • 都是能存储一连串数据的容器 。 • 区别 1 ： set 会自动给其中的 元素从小到大排序，而 vector 会保持插入时的顺序。 • 区别 2 ： set 会把重复的元素 去除，只保留一个，即去重。 • 区别 3 ： vector 中的元素在内 存中是连续的，可以高效地按 索引随机访问， set 则不行。 • 区别 4 4 ： set 中的元素可以高 效地按值查找，而 vector 则 低效。 set 的排序： string 会按“字典序”来排 • set 会从小到大排序，对 int 来 说就是数值的大小比较。那么对 字符串类型 string 要怎么排序 呢？ • 其实 string 类定义了运算符重 载 < ，他会按字典序比较两个 字符串。所谓字典序就是优先比 较两者第一个字符（按 ASCII 码比较），如果相等则继续比较
