voidCreate();//的功能是：创建新的通讯录。
voidAdd();//在通讯录的末尾，写入新的信息，并返回选单
voidFind();//查找记录
voidAlter();//修改记录如果未找到要修改的人，则提示通讯录中没有此人的信息，并返回选单。
voidDelete();//删除某人的信息，如果未找到要删的人，提示通讯录中没有此人的信息，并返回选单。

printf("name\t\t\tphone\n\n");
for(i=0;i<NUM;i++)
printf("%s\t\t\t%s\n",man[i].name,man[i].phone);
}

‘陆’ 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。

‘柒’ c语言通讯录编写

靠山山倒，靠树树倒，靠自己最好!
自己写吧，一个
结构体{
姓名;
性别;
年龄;
手机;
}
如果不会用链表，那你就用数组!
录入:就是往数组里写入数据
删除:就清为0就可以了呗
查询:就是从数组的第一项到保存数查找一遍喽。

，你是在做课程设计吧?计科的?
