本次程序设计的主要目的是建立一个链表类模板，以实现不同数据类型的实例化以及对不同数据类型链表的相同操作：在链表末尾或链表中某数据域节点后插入数据域为value的节点；删除数据域值为value的节点，若没有此节点则报错；按顺序打印链表所有节点数据域的值。-The main purpose of this program is designed to create a linked list class template to achieve different data types and instances of the same operation on the list of different types of data: In the list or the list after the end of a data field for the value data field node insertion node　 delete data field value value of the node, if the node is no error　values ​ ​ in order to print the list of all nodes in the data field.
