list数据存取
#include <list> #include <iostream> using namespace std; //list数据存取 void printList(const list<int>&L){ for (list<int>::const_iterator it = L.begin(); it != L.end(); it ++){ cout << *it << ‘ ‘; } cout << endl; } void test01(){ list<int>L1; L1.push_back(10); L1.push_back(20); L1.push_back(30); L1.push_back(40); //l1[0]不可以用[]方式访问list容器中的元素 //l1.at(0) 不可以用at方式访问list容器的元素 cout << "第一个元素为:" << L1.front() << endl; cout << "最后一个元素:" << L1.back() << endl; //迭代器不支持随机访问的。 list<int>::iterator it = L1.begin(); it ++; it --; //it = it + 1 //错误,不支持随机访问 } int main(){ test01(); return 0; }
