一篇文章让你轻松理解C++中vector和list区别

        #include <iostream>
        #include <vector>
        #include <list>
        using namespace std;
        
        int main( void )
        {
                vector<int> v; 
                list<int> l;
                
                for (int i=0; i<8; i++)     //往v和l中分别添加元素
                {
                        v.push_back(i);
                        l.push_back(i);
                }
                
                cout << "v[2] = " << v[2] << endl;
                //cout << "l[2] = " << l[2] << endl;       //编译错误,list没有重载[]
                cout << (v.begin() < v.end()) << endl;
                //cout << (l.begin() < l.end()) << endl;   //编译错误,list::iterator没有重载<或>
                cout << *(v.begin() + 1) << endl;
                
                vector<int>::iterator itv = v.begin();
                list<int>::iterator itl = l.begin();
                itv = itv + 2;
                //itl = itl + 2;                  //编译错误,list::iterator没有重载+
                itl++;itl++;                    //list::iterator中重载了++，只能使用++进行迭代访问。
                cout << *itv << endl;
                cout << *itl << endl;
        
                return 0;
        }
