例如,当我们使用标准库容器如std::vector、std::string等时,如果需要将一个容器的内容转移到另一个容器中,可以使用移动语义来避免不必要的复制操作。这可以显著提高 阅读全文 posted @ 2024-09-17 16:38 daligh 阅读(19) 评论(0) 推荐(0) 编辑

一、C++ 中vector的使用方法 vector是C++标准模板库(STL)中的部分内容,是一个十分有用的容器,它是一个多功能的,能够操作多种数据结构和算法的模板类和函数库。 作用:它能够像容器一样存放各种类型的对象,简单地说,vector是一个能够存放任意类型的动态数组,能够增加和压缩数据。
