在 STL 中实现列表的 C++ 程序

2023-06-20 11:18:03 322

列表是允许非连续内存分配的序列容器。与向量相比，列表的遍历速度较慢，但一旦找到位置，插入和删除就会很快。

功能及说明：

From main(), we have called following functions:
   fl.resize() = Returns the resize of list.
   fl.push_front() = It is used to push elements into a list from the front.
   fl.remove() = Deletes elements from list.
   fl.unique() = Deletes duplicate elements from list.
   fl.reverse() = Reverses the list.
   fl.front() = Returns the front element of list.

示例代码

#include 
using namespace std;
int main() {
   list l;
   list::iterator it;
   int c, i;
   while (1) {
      cout<<"1.Insert Element at the Front"<>c;
      switch(c) {
         case 1:
            cout<<"输入要在前面插入的值： ";
            cin>>i;
            l.push_front(i);
         break;
         case 2:
            cout<<"输入要在最后插入的值： ";
            cin>>i;
            l.push_back(i);
         break;
         case 3:
            i= l.front();
            l.pop_front();
            cout<<"Element "<>i;
            if (i <= l.size())
               l.resize(i);
            else
               l.resize(i, 0);
         break;
         case 9:
            cout<<"输入要删除的元素： ";
            cin>>i;
            l.remove(i);
         break;
         case 10:
            l.unique();
            cout<<"Duplicate Items Deleted"<输出结果1.Insert Element at the Front
