任务描述  
使用C语言实现通讯录。  
功能要求  
（1）创建通讯录。输入学生的姓名、学号和电话号码等，并将它们存放在对应的数组中；每输入一组数据，记录数增1。  
（2）显示通讯录。将记录学生姓名、学号和电话号码的数组中的数据一一输出到屏幕上，可以根据实际记录数确定循环次数。  
（3）查询通讯录。分别按学号和姓名进行查询，查询时将输入的信息通过循环与相应数组成员一一进行比较。  
（4）修改通讯录。输入需要修改记录的学号，通过循环查找到该记录后，再输入新数据替代原有数据。  
（5）添加通讯录。判断输入的学号是否重复，若不重复再将输入的信息添加到对应的数组中，每输入一组数据，记录数增1。  
（6）删除通讯录。分别按学号和姓名进行删除。  
（7）排序通讯录。分别按学号和姓名进行排序。排序方式可以是升序或降序。  
（8）退出。
