数据结构实验报告之链表顺序表的操作

1、编写程序实现顺序表的各种基本运算:初始化、插入、删除、取表元素、求表长、输出表、销毁、判断是否为空表、查找元素。在此基础上设计一个主程序完成如下功能:

1)初始化顺序表L;

2)依次在表尾插入a,b,c,d,e五个元素;

3)输出顺序表L;

4)输出顺序表L的长度;

5)判断顺序表L是否为空;

6)输出顺序表L的第4个元素;

7)输出元素c的位置;

8)在第3个位置上插入元素f,之后输出顺序表L;

9)删除L的第2个元素,之后输出顺序表L;

10)销毁顺序表L。

2、编写程序实现单链表的各种基本运算:初始化、插入、删除、取表元素、求表长、输出表、销毁、判断是否为空表、查找元素。在此基础上设计一个主程序完成如下功能:

1)初始化单链表L;

2)依次在表尾插入a,b,c,d,e五个元素;

3)输出单链表L;

4)输出单链表L的长度;

5)判断单链表L是否为空;

6)输出单链表L的第4个元素;

7)输出元素c的位置;

8)在第3个位置上插入元素f,之后输出单链表L;

9)删除L的第2个元素,之后输出单链表L;

10)销毁单链表L。
