C++实现简单通讯录系统
作者:hypnumberone
这篇文章主要为大家详细介绍了C++实现简单通讯录系统,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了C++实现简单通讯录系统的具体代码,供大家参考,具体内容如下
需求分析:
1.通讯录可以添加联系人。
2.通讯录可以显示所有联系人。
3.通讯录可以查找联系人。
4.通讯录可以删除联系人。
5.通讯录可以修改联系人。
6.可以清空通讯录。
7.退出通讯录。
项目代码:
#include<iostream> #include<string> #include<stdlib.h> using namespace std; #define MAX 1000 typedef struct person { //定义一个联系人的结构体 string name; string sex; int age; int telnumber; string addr; }person; typedef struct Addressbooks { //定义一个通讯录,自带一个联系人数组,里面可以存放MAX个联系人 struct person personArray[MAX]; int m_size=0; }Addressbooks; void Menu() { //菜单函数 cout << " 通讯录管理系统" << endl; cout << "" << endl; cout << "" << endl; cout << " 1--添加联系人" << endl; cout << " 2--显示联系人" << endl; cout << " 3--删除联系人" << endl; cout << " 4--查找联系人" << endl; cout << " 5--修改联系人" << endl; cout << " 6--清空联系人" << endl; cout << " 7--退出联系人" << endl; } void addPerson(Addressbooks* abs) { //添加联系人的函数实现 if (abs->m_size == MAX) { cout << "此通讯录已满,不能添加\n" << endl; } else { string name; string sex; int age; int telnumber; string addr; cout << "请输入联系人姓名:" << endl; cin >> name; abs->personArray[abs->m_size].name = name; cout << "请输入联系人性别:" << endl; cin >> sex; abs->personArray[abs->m_size].sex = sex; cout << "请输入联系人年龄:" << endl; cin >> age; abs->personArray[abs->m_size].age = age; cout << "请输入联系人电话号码:" << endl; cin >> telnumber; abs->personArray[abs->m_size].telnumber = telnumber; cout << "请输入联系人家庭住址:" << endl; cin >> addr; abs->personArray[abs->m_size].addr = addr; abs->m_size++; cout << "添加成功!!!" << endl; system("pause"); //利用这行语句达到一个显示按任意键继续的效果 system("cls"); //清空整个屏幕,刷新屏幕 } } void showPerson(Addressbooks* abs) { //显示整个通讯录中联系人的函数实现 for (int i = 0; i < abs->m_size; i++) { cout << abs->personArray[i].name << " " << abs->personArray[i].sex << " " << abs->personArray[i].age << " " << abs->personArray[i].telnumber << " " << abs->personArray[i].addr << endl; } system("pause"); system("cls"); } int selectPerson(Addressbooks* abs,string name) { //查询输入的联系人是否存在,存在返回联系人坐在的下标值,不存在则返回-1 for (int i = 0; i < abs->m_size; i++) { if (abs->personArray[i].name == name) { return i; } } return -1; } void deletePerson(Addressbooks* abs) { //删除联系人的函数实现 string name; cout << "请输入删除联系人的名字:" << endl; cin >> name; if (selectPerson(abs, name) != -1) { for (int i = selectPerson(abs, name); i < abs->m_size;i++) { abs->personArray[i] = abs->personArray[i + 1]; } abs->m_size--; cout << "删除成功" << endl; } else { cout << "查无此人" << endl; } system("pause"); system("cls"); } void searchPerson(Addressbooks* abs) { //查询联系人并输出相关信息的函数实现 string name; cout << "请输入联系人姓名:" << endl; cin >> name; int ret = selectPerson(abs, name); if (ret != -1) { cout << abs->personArray[ret].name << " " << abs->personArray[ret].sex << " " << abs->personArray[ret].age << " " << abs->personArray[ret].telnumber << " " << abs->personArray[ret].addr << endl; } else { cout << "查无此人" << endl; } system("pause"); system("cls"); } void revisePerson(Addressbooks* abs) { //修改联系人的函数实现 string name; cout << "请选择联系人 :" << endl; cin >> name; int ret; ret = selectPerson(abs, name); if (ret != -1) { cout << " 1--修改姓名" << endl; cout << " 2--修改性别" << endl; cout << " 3--修改年龄" << endl; cout << " 4--修改电话号码" << endl; cout << " 5--修改家庭住址" << endl; cout << " 0--退出" << endl; int chosen; while (1) { cout << "选择:"<<endl; cin >> chosen; switch (chosen) { case 1: { string name2; cout << "修改名字:" << endl; cin >> name2; abs->personArray[ret].name = name2; break; } case 2: { string sex; cout << "修改性别:" << endl; cin >> sex; abs->personArray[ret].sex = sex; break; } case 3: { int age; cout << "修改年龄:" << endl; cin >> age; abs->personArray[ret].age = age; break; } case 4: { int tel; cout << "修改电话号码:" << endl; cin >> tel; abs->personArray[ret].telnumber = tel; break; } case 5: { string addr; cout << "修改住址:" << endl; cin >> addr; abs->personArray[ret].addr = addr; break; } case 0: goto FLAG1; default: break; } } } else { cout << "查无此人!!!" << endl; } FLAG1: system("pause"); system("cls"); } void clear(Addressbooks* abs) { abs->m_size = 0; cout << "此通讯录已清空!!!" << endl; system("pause"); system("cls"); } int main() { Addressbooks book1; //先定义一个通讯录,并添加一个联系人hyp book1.personArray[0].name = "hyp"; book1.personArray[0].sex = "man"; book1.personArray[0].age = 21; book1.personArray[0].telnumber = 76766767; book1.personArray[0].addr = "重庆"; book1.m_size = 1; int chosen; while (1) { Menu(); cout << "选择:" ; cin >> chosen; switch (chosen) { case 1: //添加联系人 addPerson(&book1); break; case 2: //显示联系人 showPerson(&book1); break; case 3: //删除联系人 deletePerson(&book1); break; case 4: //查找联系人 searchPerson(&book1); break; case 5: //修改联系人 revisePerson(&book1); break; case 6: //清空联系人 clear(&book1); break; case 7: //退出通讯录 return 0; break; default: break; } } return 0; }
效果:
显示联系人
添加联系人
后面效果就不一一显示了
