C++编写通讯录控制台版

C++编写通讯录控制台版

效果演示：

下载：程序

主要用到的知识点：

结构体

结构体的创建以及使用，利用数组创建多个结构体对象，在本程序中，利用宏define MAX 1000 来制约了数组的大小，从而达到控制通讯录大小的目的。

指针

AddBooks abs 本程序中用实例化了对象，并在函数中传入该对象的指针。

代码部分

#include <iostream>
#include <windows.h>
#define MAX 1000
using namespace std;

struct Person
{
    string name;
    string m_Sex;
    string m_Age;
    string m_Phone;
    string m_Addr;
};

struct AddBooks
{
    Person PersonArray[MAX];
    int m_Size;   //通讯录人数个数
};

//菜单函数显示菜单
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;
}
//添加联系人函数
void addPerson(AddBooks* abs) {
    if (abs->m_Size==MAX)
    {
        cout << "通讯录已满，无法添加" << endl;
        return;
