#include <iostream> #include "map_struct.h" #include <map> using namespace std; typedef struct real_data{ int reg_addr; string desc; }HistRecord; int main() { cout << "Hello world!" << endl; map<int, HistRecord> m_upmcsbConf; HistRecord histRecordData; histRecordData.reg_addr = 1; histRecordData.desc="aaaaaaaaaa"; m_upmcsbConf.insert(pair<int,HistRecord>(1,histRecordData)); histRecordData.reg_addr = 2; histRecordData.desc="bbbbbb"; m_upmcsbConf.insert(pair<int,HistRecord>(2,histRecordData)); map<int, HistRecord>::iterator it; for ( it = m_upmcsbConf.begin(); it != m_upmcsbConf.end(); ++it) { cout << it->first << " - > " << it->second.reg_addr << endl; } return 0; }
Map遍历操作以及插入操作。
要点:insert插入要用pair, 遍历的时候it->first的first后面没有first()
map获取其中的元素值,则像数组一样直接操作:例:
m_upmcsbConf[i]则取出real_data结构体。
list用法:
list是双向链表,list无法指定取某元素的值。没有list.at函数,
vector
vector是开辟一段连续的内存空间,与list相比,随机访问速度快,但插入删除操作慢
