先定义头文件

#ifndef __CONTACT_H__ 
#define __CONTACT_H__ 
 
#define NAME_LEN 10 
#define SEX_LEN 6 
#define TELE_LEN 12 
#define ADDR_LEN 20 
#define MAX_PEO 1000 
 
typedef struct PEO 
{ 
 char name[NAME_LEN]; 
 int age; 
 char sex[SEX_LEN]; 
 char tele[TELE_LEN]; 
 char addr[ADDR_LEN]; 
}Peo, *PPEO; 
 
typedef struct Contact 
{ 
 Peo nb[MAX_PEO]; 
 int count;//记录有效个数 
}PCON,*Pcon; 
 
void add_peo(Pcon pcon); 
void del_peo(Pcon pcon); 
void search(Pcon pcon); 
void modify(Pcon pcon); 
void show(Pcon pcon); 
void clear(Pcon pcon); 
 
 
#endif

然后创建contact.c，将函数写入

#include 
#include  
#include"contact.h" 
 
void add_peo(Pcon pcon) 
{ 
 if (pcon->count <= MAX_PEO) 
 { 
  printf("请输入姓名："); 
  scanf("%s", pcon->nb[pcon->count].name); 
  printf("请输入年龄："); 
  scanf("%d", &pcon->nb[pcon->count].age); 
  printf("请输入性别："); 
  scanf("%s", pcon->nb[pcon->count].sex); 
  printf("请输入电话："); 
  scanf("%s", pcon->nb[pcon->count].tele); 
  printf("请输入地址："); 
  scanf("%s", pcon->nb[pcon->count].addr); 
  pcon->count ++; 
  printf("添加成功！\n"); 
 } 
 else 
  printf("电话本已满！"); 
} 
 
void show(Pcon pcon) 
{ 
 int i=0; 
 printf("姓名 年龄 性别   电话    地址\n"); 
 for(i=0;icount;i++) 
 { 
  printf("%s%8d%8s%15s%18s\n",pcon->nb[i].name,pcon->nb[i].age,pcon->nb[i].sex,pcon->nb[i].tele,pcon->nb[i].addr); 
 } 
} 
 
int find(char *c,Pcon pcon) 
{ 
 int i=0; 
 for(;icount;i++) 
 { 
  if(strcmp(c,pcon->nb[i].name)==0) 
   return i; 
    
 } 
 return -1; 
} 
void del_peo(Pcon pcon) 
{ 
 char nam[NAME_LEN]; 
 int index=0; 
 printf("请输入你想删除的人："); 
 scanf("%s",nam); 
 index = find(nam,pcon->nb[index].name); 
 for(;index<=pcon->count-1;index++) 
 { 
  pcon->nb[index]=pcon->nb[index+1]; 
 } 
 pcon->count--; 
 printf("删除成功！\n"); 
} 
 
void search(Pcon pcon) 
{ 
 char nam[NAME_LEN]; 
 int i=0; 
 printf("请输入你想查找的人："); 
 scanf("%s",nam); 
 i = find(nam,pcon->nb[i].name); 
 printf("姓名 年龄 性别   电话    地址\n"); 
 printf("%s%8d%8s%15s%20s\n",pcon->nb[i].name, 
   pcon->nb[i].age,pcon->nb[i].sex, 
   pcon->nb[i].tele,pcon->nb[i].addr); 
} 
 
void modify(Pcon pcon) 
{ 
 char nam[NAME_LEN]; 
 int i=0; 
 printf("请输入你想修改的人："); 
 scanf("%s",nam); 
 i = find(nam,pcon->nb[i].name); 
 pcon->nb[i] = pcon->nb[-1]; 
 printf("请输入姓名："); 
 scanf("%s", pcon->nb[i].name); 
 printf("请输入年龄："); 
 scanf("%d", &pcon->nb[i].age); 
 printf("请输入性别："); 
 scanf("%s", pcon->nb[i].sex); 
 printf("请输入电话："); 
 scanf("%s", pcon->nb[i].tele); 
 printf("请输入地址："); 
 scanf("%s", pcon->nb[i].addr); 
 printf("添加成功！\n"); 
} 
 
void clear(Pcon pcon) 
{ 
 pcon->count = 0; 
}

最后写入函数主体

#include  
#include "contact.h" 
 
#define _CRT_SECURE_NO_WARINGS_ 
void print_menu() 
{ 
 printf("****************************\n"); 
 printf("*** 1>add  2>del ***\n"); 
 printf("*** 3>show  4>search ***\n"); 
 printf("*** 5>modify 6>clear ***\n"); 
 printf("****************************\n"); 
} 
 
int main() 
{ 
 PCON con; 
 int input = 1; 
 con.count = 0; 
 while (input) 
 { 
  print_menu(); 
  printf("请选择:"); 
  scanf("%d", &input); 
 // system("cls"); 
  switch (input) 
  { 
  case 1: 
   add_peo(&con); 
   break; 
  case 2: 
   del_peo(&con); 
   break; 
  case 3: 
   show(&con); 
   break; 
  case 4: 
   search(&con); 
   break; 
  case 5: 
   modify(&con); 
   break; 
  case 6: 
   clear(&con); 
   break; 
  default: 
   break; 
  } 
 } 
 
 return 0; 
}
