本文實例為大家分享了C語言實現通訊錄功能的具體代碼，供大家參考，具體內容如下

先定義頭文件

#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;//記錄有效個數 }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

然后創建contact.c，將函數寫入

#include<stdio.h> #include <string.h> #include"contact.h"  void add_peo(Pcon pcon) {  if (pcon->count <= MAX_PEO)  {   printf("請輸入姓名：");   scanf("%s", pcon->nb[pcon->count].name);   printf("請輸入年齡：");   scanf("%d", &pcon->nb[pcon->count].age);   printf("請輸入性別：");   scanf("%s", pcon->nb[pcon->count].sex);   printf("請輸入電話：");   scanf("%s", pcon->nb[pcon->count].tele);   printf("請輸入地址：");   scanf("%s", pcon->nb[pcon->count].addr);   pcon->count ++;   printf("添加成功！/n");  }  else   printf("電話本已滿！"); }  void show(Pcon pcon) {  int i=0;  printf("姓名 年齡 性別   電話    地址/n");  for(i=0;i<pcon->count;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(;i<pcon->count;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("請輸入你想刪除的人：");  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("刪除成功！/n"); }  void search(Pcon pcon) {  char nam[NAME_LEN];  int i=0;  printf("請輸入你想查找的人：");  scanf("%s",nam);  i = find(nam,pcon->nb[i].name);  printf("姓名 年齡 性別   電話    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("請輸入你想修改的人：");  scanf("%s",nam);  i = find(nam,pcon->nb[i].name);  pcon->nb[i] = pcon->nb[-1];  printf("請輸入姓名：");  scanf("%s", pcon->nb[i].name);  printf("請輸入年齡：");  scanf("%d", &pcon->nb[i].age);  printf("請輸入性別：");  scanf("%s", pcon->nb[i].sex);  printf("請輸入電話：");  scanf("%s", pcon->nb[i].tele);  printf("請輸入地址：");  scanf("%s", pcon->nb[i].addr);  printf("添加成功！/n"); }  void clear(Pcon pcon) {  pcon->count = 0; }

最后寫入函數主體

#include <stdio.h> #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("請選擇:");   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; }
