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。
❷ 如何用C语言做通讯录
剽窃代码即可。。
已经按照你的要求做了一个，VC6上运行确认了：
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
typedefstructPersonalInfo
{
charname[50];
charaddress[30];
chartelno[30];
charpostcode[30];
structPersonalInfo*next;
}INFO;
INFO*head;
voidInitiate();
voidMenu();
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。
voidList();//的功能是：显示通讯录中的所有记录。
//初始化
voidInitiate()

❹ 编写C语言一个通讯录程序
这是我以前写的课程设计，
电子通讯录功能如下：
Function choose
1.Read
2.Append
3.Delete
4.Search
5.Save and exit
6.Quit
说明：上图是电子通讯录的主菜单，利用它，将能够轻松地录入一个朋友的电话号
码，通讯地址和出生日期，而且它还提供了检索和删除功能。在后面还将提供按生
日先后排序的功能，这些都有助于该通讯录的管理。
电子通讯录是采用线性表作为程序的基本结构的。
设计思想：
1。用顺序表设计电子通讯录的结构
为了表示较为复杂的数据内容，一般用结构这种数据类型，第一步就是在结构中定
义所需要的各项信息。
一般的通讯录都包括姓名，性别，出生年月，通讯地址和联系电话这几项，而
在这几项中，出生年月又包括年份，月份和日期三项，通讯地址包括邮编和家庭地
址二项，我们把这些联系较为紧密的内容又用单独的结构表示，这样就产生了电子
通讯录的基本结构：
struct addr /*通讯地址结构定义*/
{ char post_num[10]; /*邮编*/
char addr[40]; /*家庭地址*/
};
struct birth /*出生年月结构定义*/
{ int year; /*年份*/
int month; /*月份*/
int day; /*日期*/
};
struct friend /*电子通讯录结构定义*/
{ int number; /*序号*/
char name[20] /*姓名*/
char sex; /*性别*/
struct birth birth; /*出生年月*/
struct addr addr; /*通信地址*/
char telephone[13]; /*联系电话*/
};
定义的主结构friend包含了前述的五项内容 name,sex,和telephone分别代表
了姓名，性别和联系电话。为了让结构中的各项组分更加清晰，定义了二个
小结构birth 和addr分别代表出生年月和通讯地址，因此实际上friend包含了
8项内容。
有了结构定义后，我们可以很轻松地构造出电子通讯录的主体：
stryct friend friends[50];
采用一维数组 friends[50]，正是用到了顺序表这种最简单的数据结构来表示
问题。
2.增添电子通讯录中的内容
对于电子通讯录这样一张顺序表来说，内容的录入是必不可少的操作。由
于采用的是顺序存储结构。这项工作很简单，只需要在把输入的信息按顺序放
在空的friends数组元素中即可。函数Data_Input完成了信息的录入工作：
void Data_input(int j)
{
friends[j].number=j;
printf("\n\n\n\tNo %d record",j);
printf("\n\n\tName:"); /*读入姓名*/
scanf("%s",friends[j].name);
printf("\n\tSex(m/f):"); /*读入姓别*/
scanf("%c",&friends[j].sex);
printf("\n\tbirthday:"); /*读入出生年月*/
printf("\n\t\tyear:");
scanf("%d",&friends[j].birth.year);
printf("\n\t\tmonth");
scanf("%d",&friends[j].birth.month);
printf("\n\t\tday");
scanf("%d",&friends[j].birth.day);
printf("\n\tPost number:"); /*读入邮编*/
scanf("%s",friends[j].addr.post_num);
printf("\n\tAddress:"); /*读入家庭地址*/
scanf("%s",friends[j].addr.addr);
printf("\n\ttelephone:"); /*读入联系电话*/
scanf("%s",friends[j].telephone);
}
