你的num应该是char类型吧？
还有，name数组长度不用那么大啊，好浪费空间！
我测试了下，没什么问题，要是有什么问题可以hi我
另外,站长团上有产品团购,便宜有保证

㈡ C语言的课程设计，做的是全班同学通讯录，然而我并不懂程序是怎样调用的

里面包括文件的调用，各种查找，筛选的函

㈢ C语言编辑 高分 班级通讯录管理系统

VC的，可以稍加修改，TC和VC差别不大，你可以先测试下，可以留言我看到就会给你发过去

㈣ 用c语言编写通讯录程序

这个属于基本的结构体数组和文件读写操作。

㈤ C语言编程 为班里同学设计一份班级通讯录。编写功能菜单。记录每一位同学的学号，姓名，性别，手机号码

这建议你看下c primer plus这本书的最后一章，有详细的介绍。

㈥ c语言实验题，使用共同体类型，建立一个班级通讯录，其中包括30名学生和5名任课教师

union_people
{
struct{
//里面自己写

}student;

struct{
}teacher;

}
