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{ ,,,, };
     //容器
     myint.push_back();
     int a[] = { ,,,, };

     //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{ ,,,, };
     mylist.push_front();
     //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();
 }
