voidAdd();//在通訊錄的末尾，寫入新的信息，並返回選單
voidFind();//查找記錄
voidAlter();//修改記錄如果未找到要修改的人，則提示通訊錄中沒有此人的信息，並返回選單。
voidDelete();//刪除某人的信息，如果未找到要刪的人，提示通訊錄中沒有此人的信息，並返回選單。

⑸ C語言設計個人通訊錄管理系統
1、創建學生社團管理系統的歡迎界面，該歡迎界面以圖片的方式呈現，系統啟動時再屏幕中居中顯示。
⑹ 用c語言編寫一個通訊錄，並對他進行增加，查詢，刪除，修改，顯示記錄等操作，要寫出源代碼並畫出流程圖
這個是我編的，用數組和鏈表兩種功能實現的通訊錄
基本能滿足你的要求！！
代碼如下：
#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");
