⑴ 用c语言编写一个通讯录管理系统
C语言编写一个通讯录管理系统的源代码如下：
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
/*定义保存通迅录的信息*/
structfriends
{
charname[20];/*名字*/
charprovince[20];/*省份*/
charcity[20];/*所在城市*/
charnation[20];/*民族*/
charsex[2];/*性别M/F*/
intage;/*年龄*/
}
(1)通讯录管理程序c语言扩展阅读
1、在C++中应该使用inline内连函数替代宏调用，这样既可达到宏调用的目的，又避免了宏调用的弊端。
2、在C语言两个函数的名称不能相同，否则会导致编译错误。在C++中，函数名相同而参数不同的两个函数被解释为重载。
3、在大型程序中，使函数名易于管理和使用，不必绞尽脑汁地去处理函数名。

⑷ C语言，编写一个简单的通讯录管理系统
实现一个通讯录管理系统；
通讯录管理系统可以用来存储1000个人的信息，每个人的信息包括：
姓名、性别、年龄、电话、住址
**提供方法：
1. 添加联系人信息
2. 删除指定联系人信息
3. 查找指定联系人信息
4. 修改指定联系人信息
5. 显示所有联系人信息
6. 清空所有联系人
7. 以名字排序所有联系人**
1、linkman.h(头文件）
3、程序运行结果部分示范：
⑸ C语言程序设计，通讯录管理系统
/*【用C语言编写具有数据插入、修改、删除、显示和查询功能的电话薄管理程序】
1、数据包括：人名、工作单位、电话号码和E-mail地址。
2、可对记录中的姓名和电话号码进行修改。
3、可增加或删除记录。
4、可显示所有保存的记录。
5、可按人名或电话号码进行查询。
另：采用结构体数组和文件系统实现。结构体包括人名、工作单位、电话号码和E-mail

⑹ C语言设计个人通讯录管理系统
1、创建学生社团管理系统的欢迎界面，该欢迎界面以图片的方式呈现，系统启动时再屏幕中居中显示。
⑺ 用C语言. 编写一个“通讯录管理系统”程序
#include

#include
struct worker

fflush(stdin);//？清空输入缓冲区，通常是为了确保不影响后面的数据读取
getchar();
