通过C语言实现有一个通讯录
通讯录具有以下的功能1.手机用户添加 、2.手机用户删除、3.手机用户查找 、4.手机用户修改、
5.手机用户查看 、6.手机用户清空、7.手机用户排序 、8.手机用户保存、0.退出程序
代码如下：
text.c
#define _CRT_SECURE_NO_WARNINGS 1
#include "contact.h"
void menu()
{
printf("***************************************\n");
printf("**********1.手机用户添加 2.手机用户删除***********\n");
printf("**********3.手机用户查找 4.手机用户修改********\n");
printf("**********5.手机用户查看 6.手机用户清空*********\n");
printf("**********7.手机用户排序 8.手机用户保存**********\n");
printf("**********0.退出程序 **********\n");
printf("***************************************\n");
}
void text()
{

do
{

printf("请输入选择:>");

case MODIFY:

break;
default:

break;
}
} while (input);
}
