⑶ 如何用C语言做通讯录

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。

⑸ 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。
⑹ 用c语言编写一个通讯录，并对他进行增加，查询，删除，修改，显示记录等操作，要写出源代码并画出流程图
这个是我编的，用数组和链表两种功能实现的通讯录
基本能满足你的要求！！
代码如下：
#include "stdlib.h"
#define NEW (struct node *)malloc(sizeof(struct node))
struct student
{ char name[10],tel[11];
}a[20];
struct node
{ char name[20],tel[11];
struct node *next;
};
main()
{ struct student *jianli(),*delete(struct student *);
struct student *charu(struct student *);
void xianshi(struct student *);
struct node *create(),*delnode(struct node*,char *);
struct node *insert(struct node *,struct node *,char *);
void prlist(struct node *);
struct student *p;
struct node *head=NULL,*stu;
char s[80],name[20],q[80];
int c,w;
a:;
system("cls");
printf("\nEnter your choice\n");
printf("1.SHUZU\n2.LIANBIAO\n0.Quit\n");
gets(q);
w=atoi(q);
switch(w)
{ case 1:
do
{ do
{ printf("----------------------------------------------\n");
printf("******************Phone book******************\n");
printf("----------------------------------------------\n");
printf(" | | <1> Add a note | |\n");
printf(" | | <2> Show the list | |\n");
printf(" | | <3> Delete a note | |\n");
printf(" | | <4> Insert a note | |\n");
printf(" | | <0> Quit | |\n");
printf("----------------------------------------------\n");
printf(" Enter your choice(0-4):");
gets(s);
c=atoi(s);
