C++标准库双向链表 list 中的insert函数实现。

news 2024/11/15 20:40:09

 C++Primer中文版（第五版）：

   //运行时错误：迭代器表示要拷贝的范围，不能指向与目的位置相同的容器
    slist.insert(slist.begin(),slist.begin(),slist.end());
    
如果我们传递给insert一对迭代器，它们不能指向添加元素的目标容器。
       在新标准下，接受元素个数范围的insert版本返回指向第一个新加入元素的迭代
    
器。（在旧版本的标准库存中，这些操作返回void。）如果范围为空，不插入任何元素，insert
操作会将第一个参数返回。
 

例子1：

int main() {list<string> sl1 = { "1","2","3" };_DList<string> sl2 = { "1","2","3" };vector<string> v = { "quasi", "simba","frollo","scar" };//将v的最后两个元素添加到list的开始位置sl1.insert(sl1.begin(), v.end() - 2, v.end());sl2.std_insert(sl2.begin(), v.end() - 2, v.end());_pn(sl1);_pn(sl2);cout << "----------------------------------------------------------\n";//添加一列表sl1.insert(sl1.end(), { "4","5","6","7","中文","8","9" });sl2.std_insert(sl2.end(), { "4","5","6","7","中文","8","9" }); _pn(sl1);_pn(sl2);cout << "----------------------------------------------------------\n";//复制自己(旧版会运行时错误，迭代器表示要拷贝的范围，不能指向与目的位置相同的容器）sl1.insert(sl1.begin(), sl1.begin(), sl1.end());sl2.std_insert(sl2.begin(), sl2.begin(), sl2.end());_pn(sl1);_pn(sl2);}

结果：

例子2：

 
int main() {_DList<string> lst1;list<string> lst2;string word;auto iter1 = lst1.begin();auto iter2 = lst2.begin();while (cin >> word) {iter1 = lst1.std_insert(iter1, word); //等价于调用push_front_pn(lst1);iter2 = lst2.insert(iter2, word); //等价于调用push_front_pn(lst2);}
}

结果：

_DList中的实现：

主要函数：
