C++经验：常用的头文件
沝㴇淼㵘 更多可见https://bbs.csdn.net/topics/350008664
C++的头文件很多，这里就说常用的头文件.
#include<iostream>//引入C++语言输入输出流
#include<cstdio>//引入C语言输入输出流并用C++打开 ①
#include<algorithm>//引入此头文件后可用此文件的各种函数 ②
#include<cmath>//引入包含数学函数的头文件 ③
//后面的头文件有点少用Ø≒Ø
#include<string>//引入字符串等
#include<cstring>//引入C语言的字符串等 ④
#include<vector>//引入动态数组 ⑤
#include<queue>//引入队列 ⑥
#include<stack>//引入栈 ⑦
#include<set>//引入集合 ⑧
#include<map>//引入映射表 ⑨
①常用的有freopen(……);，scanf(……);，printf(……);
②该头文件包含了一些算法，程序开头加zhi上这个头文件，就可以直接调用里面的函数了，不用再自己手写。但是一些复杂的算法还是要自己写的。另外可以看看这个http://www.cplusplus.com/reference/algorithm/

④常用的函数有memset(……);
