C++通讯录

前言

作为一个偷偷学C++的“内卷王”，我（不知道为什么）喜欢冗长的代码和代码段，还有一堆结尾的分号。

bilibili的黑马程序员的教程很好，大家可以看一下。

我借助黑马程序员的视频做了一个通讯录，虽然有亿~~~点点长，但只有5457字节，真的很不简单。

好了，源代码出炉啦！

源代码

#include <iostream>
#include <string>//主要就是保守一点儿。
using namespace std;

#define MAX 1000
//最大值，不过没太多必要~吧

struct Person{
    string name;
    short sex;
    short age;
    string phone;
    string addr;
};
//分号！！！（撕心裂肺）

struct Addresbook{
    struct Person personArray[MAX];
    short size;
};

void ShowMenu(){
    cout << "1.添加联系人。" << endl;
    cout << "2.显示全部联系人" << 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;
}

void addPerson(Addresbook * abs){
    if (abs->size == MAX){
        cout << "通讯录已满，无法添加！" << endl;
        return; //wwwwwwwwwhat???
    }
    else{
        string addname;
        cout << "请输入姓名：";

        abs->personArray[abs->size].name = addname;
        //没学指针与数组的搭配的我：？？？？？
