本文实例为大家分享了c++实现简易通讯录管理系统的具体代码,供大家参考,具体内容如下
建议收藏,亲手写一遍代码,感受指针神奇的魅力;
可以帮助你更好的巩固知识体系,熟悉指针,结构体与函数一起使用时的妙处
完成通讯录管理系统所需知识体系
1.结构体
2.指针
3.函数的封装
4.指针与函数的结合使用
5.指针与结构体的结合使用
struct person
{
string name;//姓名
string sex; //性别
int age; //年龄
string phone;//手机号
string home;//地址
};
struct addressbook
{
struct person personArray[MAX]; //通讯录扩展到100;
int size=0; //当前联系人个数(后面就相当于i++)
};
void menu();//菜单
void putit(addressbook* add);//添加联系人
void showperson(addressbook* add);// 显示联系人
int if_include(addressbook* add, string name);//判断联系人
void deleteperson(addressbook* add, int i);//删除联系人
void findPerson( addressbook* add);//查找联系人
void cleanperson(struct addressbook* add);//清空所有联系人
void menu()
{
cout << endl;
cout << "**********【主菜单】************" << 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 << "---------0.退出通讯录:---------" << endl;
cout << "*******************************" << endl;
}
void putit(addressbook* add)//添加联系人功能
{
if (add->size == MAX)
cout << "通讯录已满" << endl;
else
{
string name;
string sex;
int age;
string phone;
string home;
cout << "请输入姓名" << endl;
cin >> name;
add->personArray[add->size].name = name;
cout << "请输入姓别" << endl;
cin >> sex;
add->personArray[add->size].sex = sex;
cout << "请输入年龄" << endl;
cin >> age;
add->personArray[add->size].age = age;
cout << "请输入电话号码" << endl;
cin >> phone;
add->personArray[add->size].phone = phone;
cout << "请输入家庭住址" << endl;
cin >> home;
add->personArray[add->size].home = home;
add->size++;
cout << "添加联系人成功" << endl;
}
system("pause");
system("cls");
menu();
}
有人问添加联系人函数中为什么要使用指针?
因为值传递中形参无法改变实参;
而利用指针的地址传递可以通过函数中的形参改变实参;
具体原理可以参考博主之前的指针基础和指针进阶内容]
