前言
C++list的使用：尾插、头插、insert、erase、reverse、sort等的介绍
一、尾插、头插、insert、erase
#include <iostream>
#include <list>using namespace std;void test_list1()
{list<int> lt;lt.push_back(1);lt.push_back(2);lt.push_back(3);lt.push_back(4);lt.push_back(5);lt.push_front(10);lt.push_front(20);for (auto e : lt){cout << e << " ";}cout << endl;// 在第5个位置插入数据// vector v.insert(v.begin() + 5, val)list<int>::iterator it = lt.begin();for (size_t i = 0; i < 5; i++){++it;}lt.insert(it, 66);for (auto e : lt){cout << e << " ";}cout << endl;it = find(lt.begin(), lt.end(), 3);if (it != lt.end()){lt.insert(it, 100);*it *= 2;// insert 完后it不失效}for (auto e : lt){cout << e << " ";}cout << endl;it = find(lt.begin(), lt.end(), 2);if (it != lt.end()){lt.erase(it);//*it *= 2; // 会强制报错// erase 后it 失效}for (auto e : lt){cout << e << " ";}cout << endl;// 删除所有的偶数it = lt.begin();while (it != lt.end()){if (*it % 2 == 0){it = lt.erase(it);}else{++it;}}for (auto e : lt){cout << e << " ";}cout << endl;}int main()
{test_list1();return 0;
}
二、reverse、sort
void test_list02()
{list<int> lt;lt.push_back(1);lt.push_back(2);lt.push_back(3);lt.push_back(4);lt.push_back(5);lt.push_front(10);lt.push_front(20);for (auto e : lt){cout << e << " ";}cout << endl;reverse(lt.begin(), lt.end());for (auto e : lt){cout << e << " ";}cout << endl;lt.reverse();for (auto e : lt){cout << e << " ";}cout << endl;//sort(lt.begin(), lt.end());//for (auto e : lt)//{// cout << e << " ";//}//cout << endl;lt.sort();for (auto e : lt){cout << e << " ";}cout << endl;}
