4.STL六大组件

代码示例

#include <vector>
#include <list>
#include <iostream>
#include <algorithm>
using namespace std;


void main1()
{
    vector<int> myint{ 1,2,3,4,5 };
    //容器
    myint.push_back(10);
    int a[5] = { 1,2,3,4,5 };

    //算法
    for_each(myint.begin(), myint.end(), [](int x) {cout << x << endl; });
    
    //迭代器
    //auto ix = myint.begin() + 2;//指针
    for (auto ib = myint.begin(), ie = myint.end(); ib != ie; ib++)
    {
        cout << *ib << endl;
    }
    cin.get();
}

void main()
{
    list<int> mylist{ 1,2,3,4,5 };
    mylist.push_front(10);
    //不能对链表进行这样操作
    //auto ib = mylist.begin() + 2;
    //链表每次只能前进一个,迭代器会自动适应容器
    auto ib = mylist.begin()++;

    cin.get();
}
