c语言简易通讯录
Ⅰ 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)c语言简易通讯录扩展阅读
1、在芦拿哪C++中应该使用inline内连函数替代宏调用，这样陪码既可达到宏调用的目的，又避免了宏调用的弊端敏橘。
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。

拓展资料
C语言是一门通用计算机编程语言，应用广泛。C语言的设计目标是提供一种能以简易的方式编译、处理低级存储器、产生少量的机器码以及不需要任何运行环境支持便能运行的编程语言。
尽管C语言提供了许多低级处理的功能，但仍然保持着良好跨平台的特性，以一个标准规格写出的C语言程序可在许多电脑平台上进行编译，甚至包含一些嵌入式处理器（单片机或称MCU）以及超级电脑等作业平台。
Ⅷ 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**
