通讯录是一个可以记录亲人、好友信息的工具。
本教程主要利用C++来实现一个通讯录管理系统
系统中需要实现的功能如下:
#include
using namespace std;
//菜单界面
void showMenu()
{
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 << "***** 0、退出通讯录 *****" << endl;
cout << "***************************" << endl;
}
int main() {
showMenu();
system("pause");
return 0;
}
先输出菜单,对利用循环体,只有输入“0”时退出,可重复选择各种功能
在头文件下方添加一个宏定义一个全局变量并赋值为1000来定义通讯录上限,方便后期修改通讯录上限。
#include
#include
#define MAX 1000//宏定义一个数1000
using namespace std;
退出功能:先输出菜单,对利用循环体,只有输入“0”时退出,可重复选择各种功能。
int main()
{
showMenu();//输出菜单
int select = 0;
cin >> select;
if (select == 0)
cout << "欢迎下次使用" << endl;
else
{
while (select<=MAX)
{
if (select == 0)
{
cout << "欢迎下次使用" << endl;
break;
}
}
利用switch函数来选择功能每一次使用完功能都输出菜单
菜单函数顾名思义就是调用下面的功能函数。
//菜单函数
void Menu(int select, Addressbooks* abs)
{
t
switch (select)
{
case 1://添加联系人
addPerson(abs);
showMenu();//输出菜单
break;
case 2://显示联系人
showPerson(abs);
showMenu();//输出菜单
break;
case 3://删除联系人
delPerson(abs);
showMenu();//输出菜单
break;
case 4://查找联系人
findPerson(abs);
showMenu();//输出菜单
break;
case 5://修改联系人
modifyPerson(abs);
showMenu();//输出菜单
break;
case 6://清空联系人
cleamPerson(abs);
showMenu();//输出菜单
break;
}
}
创建一个联系人结构体,结构体里面包含联系人的姓名,性别,年龄,电话,住址的信息。
在定义一个通讯录结构体,内嵌一个联系人结构体的数组,容量为"MAX",和人数的变量“Size”
//创建联系人结构体
struct Person
{
string Name;//姓名
int Sex = 0;//性别
int Age = 0;//年龄
string Phone;//电话
string Addr;//住址
};
//通讯录结构体声明
struct Addressbooks
{
struct Person personArray[MAX];
int Size=0;//初始化,不进行初始化编译器报了警告
};
定义一个结构体变量“abs”,Addressbooks abs;并对其进行初始化
并将参数"abs",和选择的功能传递给菜单函数
int main()
{
Addressbooks abs;//创建通讯录
abs.Size = 0;//通讯录初始化
showMenu();//输出菜单
int select = 0;
cin >> select;
if (select == 0)
cout << "欢迎下次使用" << endl;
else
{
while (select<=6)
{
if (select == 0)
{
cout << "欢迎下次使用" << endl;
break;
}
else
{
Menu(select, &abs);//传参
cin >> select;//功能选择
}
}
system("pause");
}
return 0;
}
首先要判断通讯录是否满了,其次才能进行添加,
//添加联系人
void addPerson(Addressbooks* abs)
{
//判断通讯录是否满了
if (abs->Size == MAX)
{
cout << "通讯录已满,无法添加" << endl;
return;
}
else
{
string name;
cout << "输入姓名" << endl;
cin >> name;
abs->personArray[abs->Size].Name = name;
cout << "输入性别" << endl;
cout << "1 -- 男" << endl;
cout << "2 -- 女" << endl;
int sex = 0;
leable://goto函数返回处;;只能输入1/2
cin >> sex;
if (sex == 1 || sex == 2)
abs->personArray[abs->Size].Sex = sex;
else
{
cout << "输入错误" << endl;
cout << "输入性别" << endl;
cout << "1 -- 男" << endl;
cout << "2 -- 女" << endl;
goto leable;
}
cout << "输入年龄" << endl;
int age = 0;
cin >> age;
abs->personArray[abs->Size].Age = age;
cout << "输入电话号" << endl;
string phone = "";
cin >> phone;
abs->personArray[abs->Size].Phone = phone;
cout << "输入住址" << endl;
string addr = "";
cin >> addr;
abs->personArray[abs->Size].Addr = addr;
abs->Size++;
cout << "添加成功"<< endl;
}
}
//显示联系人
void showPerson(Addressbooks* abs)
{
if (abs->Size == 0)
{
cout << "当前通讯录为空" << endl;
}
else
{
int i;
for (i = 0; i < abs->Size; i++)
{
cout << "姓名:" << abs->personArray[i].Name << "\t";
cout << "性别:" << (abs->personArray[i].Sex == 1 ? "男" : "女") << "\t";
cout << "年龄:" << abs->personArray[i].Age << "\t";
cout << "电话:" << abs->personArray[i].Phone << "\t";
cout << "住址:" << abs->personArray[i].Addr << endl;
}
}
}
//删除联系人
//判断是否存在查询的人员,存在返回在数组中索引位置,不存在返回-1
int isExist(Addressbooks* abs, string name)
{
for (int i = 0; i < abs->Size; i++)
{
if (abs->personArray[i].Name == name)
{
return i;
}
}
return -1;
}
//删除指定联系人
void delPerson(Addressbooks* abs)
{
cout << "前请输入要删除的联系人姓名" << endl;
string name;
cin >> name;
int Return=isExist(abs, name);
if (Return != -1)
{
int i;
i= Return;
abs->personArray[i] = abs->personArray[i + 1];
abs->Size--;
cout << "????" << endl;
cout << "删除成功" << endl;
cout << "????" << endl << endl << endl;
}
else

cout << "????" << endl;
cout << "查无此人" << endl;

}
