本文实例为大家分享了C语言实现通讯录功能的具体代码，供大家参考，具体内容如下
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<stdio.h> #include <string.h> #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;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("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 <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("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; }
