该系统为通讯录系统，实现了通讯录的管理功能，增删改通讯功能。通讯录查询工作是一个很复杂的问题，在实际的工作领域中，时常会遇到要修改通讯录的问题，例如修改、删除、添加、查找等都是应用过程中十分频繁的操作，如果有一个应用软件可以使这个操作简单而富有人性化，我们就可以通过界面上的提示语言来轻松准确地完成以上操作了。 本通讯录主要涉及函数的调用、指针、哈希表等主要技术。其中，函数的调用和哈希表是技术的重点。 (The system address book system, and the address book management features, additions and deletions to communication. Directory inquiries is a very complex issue, in the actual work areas, often face the problem to modify the address book, such as modify, delete, add, find the application process are all very frequent operation, if an application can make this simple and full of humane, we are prompted by the interface language to easily and accurately complete the above operation. The book mainly related function call, pointer, hash table and other major technologies. Among them, the function call and a hash table is the focus of technology.)
