前言:
代码写的挺简单的,更像是c语言的课设,然后没有持久化的东西,之前也写过一个类似的,不过我写的纯c语言大概有1700多行,把信息全用文件存起来了,
所以如果要写完整的话,最好还是用数据库或者文件保存下来,另外这个是纯手敲视频的,练练熟练度,不喜勿喷
1. 任务需求
2. 创建项目
然后选择空项目,如果没有空项目,自己百度下插件拓展
将视图切换成解决方案的视图,就在那个视图那里选择,里面写的很清楚的,
3.代码展示
3.1 设计通讯录和联系人的结构体,注意里面的联系人结构体数组的定义数字设置成变量,是有利后期修改的
#define MAX 1000 //设计联系人的结构体 struct Person { //姓名 string m_Name; //性别 1男 2女 int m_Sex; //年龄 int m_Age; //电话 string m_Phone; //住址 string m_Addr; }; //设计通讯录的结构体 struct Addressbooks { //通讯录中保存的联系人数组 struct Person personArray[MAX]; //现在的保存的人数 int m_Size; };
3.2 菜单编写
//菜单界面 void showMenu() { 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 << "***** 0. 退出通讯录 *****" << endl; }
3.3 添加联系人
//1.添加联系人 void addPerson(Addressbooks *abs) { //判断通讯录是否已满 if (abs->m_Size==MAX) { cout << "通讯录已满,无法添加" << endl; return; } else { //添加具体联系人 //姓名 string name; cout << "请输入姓名: " << endl; cin >> name; abs->personArray[abs->m_Size].m_Name = name; //性别 cout << "请输入性别: " << endl; cout << "1 --- 男" << endl; cout << "2 --- 女" << endl; int sex = 0; while (true) { //如果输入的是1或2可以退出循环,输入错误要重新进入循环 cin >> sex; if (sex == 1 || sex == 2) { abs->personArray[abs->m_Size].m_Sex = sex; break; } cout << "输入有误,请重新输入" << endl; } //年龄 cout << "请输入年龄: " << endl; int age = 0; cin >> age; abs->personArray[abs->m_Size].m_Age = age; //电话 cout << "请输入联系电话:" << endl; string phone; cin >> phone; abs->personArray[abs->m_Size].m_Phone = phone; //住址 cout << "请输入家庭住址:" << endl; string address; cin >> address; abs->personArray[abs->m_Size].m_Addr = address; //更新通讯录人数 abs->m_Size++; cout << "添加成功!" << endl; system("pause"); //请按任意键继续 system("cls");//清屏 } }
先判断人数是否达到了上限,没有的话,再进行添加
3.4 显示联系人
void showPerson(Addressbooks *abs) { //判断通讯录中人数是否为0,如果为0,提示记录为空 //如果不为0,显示记录的联系人信息 if (abs->m_Size == 0) { cout << "当前记录为空" << endl; } else { for (int i = 0; i < abs->m_Size; i++) { cout << "姓名: " << abs->personArray[i].m_Name << " "; cout << "性别: " << (abs->personArray[i].m_Sex == 1 ? "男" : "女") << " "; cout << "年龄: " << abs->personArray[i].m_Age << " "; cout << "电话: " << abs->personArray[i].m_Phone << " "; cout << "住址: " << abs->personArray[i].m_Addr << " "; } } system("pause"); system("cls"); }
3.5 判断是否有这个人,为后面函数使用提供遍历
//检测联系人是否存在,如果存在,返回联系人所在数组的具体位置,不存在返回-1 int isExist(Addressbooks *abs,string name) { for (int i = 0; i < abs->m_Size; i++) { //找到用户输入的姓名 if (abs->personArray[i].m_Name == name) { return i; } } //如果没找到就返回-1 return -1; }
3.6 删除联系人
//3.删除指定联系人 void deletePerson(Addressbooks* abs) { cout << "请输入要删除人的名称" << endl; string name; cin >> name; int ret=isExist(abs, name); if (ret != -1) { //查找到人,要进行删除操作 for (int i = ret; i < abs->m_Size - 1; i++) { //数据迁移 abs->personArray[i] = abs->personArray[i + 1]; } abs->m_Size--; //更新人数 cout << "删除成功" << endl; } else { cout << "查无此人" << endl; } system("pause"); system("cls"); }
3.7 查找指定联系人
//4.查找指定联系人信息 void findPerson(Addressbooks* abs) { cout << "请输入您要查找的联系人r" << endl; string name; cin >> name; //判断指定的联系人是否存在联系人中 int ret=isExist(abs, name); if (ret != -1) { cout << "姓名: " << abs->personArray[ret].m_Name << " "; cout << "性别: " << (abs->personArray[ret].m_Sex == 1 ? "男" : "女") << " "; cout << "年龄: " << abs->personArray[ret].m_Age << " "; cout << "电话: " << abs->personArray[ret].m_Phone << " "; cout << "住址: " << abs->personArray[ret].m_Addr << " "; } else { cout << "查无此人" << endl; } //任意键按下后,清屏 system("pause"); system("cls"); }
3.8 修改联系人信息
//5.修改指定联系人信息 void modifyPerson(Addressbooks* abs) { cout << "请输入要修改的联系人" << endl; string name; cin >> name; int ret=isExist(abs, name); if (ret != -1) //找到指定的联系人 { //姓名 string name; cout << "请输入姓名: " << endl; cin >> name; abs->personArray[ret].m_Name = name; //性别 cout << "请输入性别" << endl; cout << "1 -- 男" << endl; cout << "2 -- 女" << endl; int sex = 0; while (true) { cin >> sex; if (sex == 1 || sex == 2) { abs->personArray[ret].m_Sex = sex; break; } cout << "输入有误,请重新输入" << endl; } //年龄 cout << "请输入年龄" << endl; int age = 0; cin >> age; abs->personArray[ret].m_Age = age; //电话 cout << "请输入联系方式:" << endl; string phone; cin >> phone; abs->personArray[ret].m_Phone = phone; //住址 cout << "请输入家庭住址" << endl; string address; cin >> address; abs->personArray[ret].m_Addr = address; cout << "修改成功" << endl; } else //未找到指定联系人 { cout << "查无此人" << endl; } system("pause"); system("cls"); }
3.9 清空联系人,这里就有点灵性了,不是覆盖,而是将size=0,非常便利
//清空联系人 void cleanPerson(Addressbooks *abs) { abs->m_Size = 0; //将当前记录人联系人置为0 cout << "通讯录已经被清空" << endl; system("pause"); system("cls"); }
4.0 主函数
int main() { //创建通讯录结构体变量 Addressbooks abs; //通讯录当前个数为0 abs.m_Size = 0; int select = 0; while (true) { //菜单调用 showMenu(); cin >> select; switch (select) { case 1: //添加联系人 addPerson(&abs); //利用地址传递,可以修饰实参 break; case 2: //显示联系人 showPerson(&abs); break; case 3: //删除联系人 deletePerson(&abs); break; case 4: //查找联系人 findPerson(&abs); break; case 5: //修改联系人 modifyPerson(&abs); break; case 6: //清空联系人 break; case 0: //退出通讯录 cout << "欢迎下次使用" << endl; system("pause"); return 0; break; default: break; } }; }
总结: 其实就是练熟练度的,走一遍开发的流程,老师讲的还是挺细的,下一篇应该就是核心篇的项目了
