使用c基础语法，编写一个简易的通讯录。主要捋顺编写程序的逻辑思维，练习结构体，数组，指针，枚举等等的运用。
#include <iostream>
#include <string>
using namespace std;
#define MAX 1000
void showMenu();
void inputInfo(struct AddressBooks* abs, int index);
void addPeople(struct AddressBooks* abs);
void showPeople(struct AddressBooks* abs);
int isExit(struct AddressBooks* abs, string iName);
void deletePeople(struct AddressBooks* abs);
void modifyPeople(struct AddressBooks* abs);
void findPeople(struct AddressBooks* abs);
void emptyPeople(struct AddressBooks* abs);
enum Function {
EXIT, ADD, SHOW, DELETE, MODIFY, FIND, EMPTY
};
struct People {
string name;
string sex;
string number;
string address;
};
struct AddressBooks {
struct People array[MAX];
int num;
};
int main()
{
//创建通讯录结构体变量
struct AddressBooks abs;
//初始化通讯录中当前人员的个数
abs.num = 0;
//功能实现
int select = 0;
while (true) {
//显示菜单
showMenu();
//选择功能
cout << "请选择一个功能：" << endl;
cin >> select;
switch (select) {
case ADD: //1、添加联系人
addPeople(&abs);
break;
case SHOW: //2、显示联系人
showPeople(&abs);
break;
case DELETE: //3、删除联系人
deletePeople(&abs);
break;
case MODIFY: //4、修改联系人
modifyPeople(&abs);
break;
case FIND: //5、查找联系人
findPeople(&abs);
break;
case EMPTY: //6、清空联系人
emptyPeople(&abs);
break;
default: //0、退出
cout << "已退出" << endl;
system("pause");
return 0;
}
}
system("pause");
}
