编写程序，实现有序链表的建立；并实现对两个有序链表的归并操作，主要实验内容如下：

1.　　定义链表的数据类型（带有头结点）；

2.　　实现链表的基本操作：初始化、销毁、有序插入；

3.　　通过键盘输入建立一个非递减有序链表（键盘输入不一定按照非递减的顺序）

4.　　对通过键盘输入而建立好的两个非递减有序链表进行归并操作，并将归并好的有序链表输出。（需要编写一个归并函数）-preparation procedures, the establishment of an orderly chain; And to achieve an orderly chain of the two merging operations, the main contents are as follows : 1. Listless definition of the data types (with the first node); 2. Listless achieve the basic operation : initialization, destruction, orderly inserted; 3. Keyboard input through the establishment of a non-regressive and orderly chain (not necessarily in accordance with the keyboard input-in descending order) 4. right links Guo keyboard input and two well-established non-regressive orderly list was merging operation and merge good and orderly chain output. (Need to prepare a merge function)
