c++实现通讯录管理系统(控制台版)

此项目适合c++初学者,针对c++基础知识,涉及到变量、结构体定义使用、数组定义使用、指针定义使用等。

运行之后的结果如下:

代码:

#include <iostream>
#include <string>
using namespace std;
#define MAX 1000//定义通讯录最大容量为1000
//联系人结构体
struct person
{
    string name;
    int sex;
    int age;
    string address;
};
//通讯录结构体
struct contact
{
    struct person p[MAX];
    int size;
};

//操作菜单
void showMenu() {
    cout << "*********通讯录管理系统**********" << endl;
    cout << "********* 1.增加联系人 **********" << endl;
    cout << "********* 2.删除联系人 **********" << endl;
    cout << "********* 3.修改联系人 **********" << endl;
    cout << "********* 4.查询联系人 **********" << endl;
    cout << "********* 5.显示联系人 **********" << endl;
    cout << "********* 6.清空通讯录 **********" << endl;
    cout << "********* 0.退出通讯录 **********" << endl;
}
//封装查询联系人是否存在
int isExist(contact* con, string name) {
    for (int i = 0; i < con->size; i++) {
        if (con->p[i].name == name) {
            return i;
        }
    }
    return -1;
}
//添加联系人函数
void addPerson(contact *con){//传入数组的指针
    if (con->size == MAX) {
        cout << "通讯录已满"<<endl;
    }
    else {

        cout << "输入姓名";
        string name;
        cin >> name;
        cout << "输入年龄";
        int age;
        cin >> age;
        cout << "输入性别1:女 2:男";
        int sex;
        cin >> sex;

        string address;
        cin >> address;
        con->p[con->size].name = name;
        con->p[con->size].age = age;
        con->p[con->size].sex = sex;
        con->p[con->size].address = address;
        con->size++;
    }
    cout << "添加成功"<<endl;
    system("pause");
}
//删除联系人函数
void deletecon(contact* con) {
    string name;
    cout << "输入要删除的姓名";
    cin >> name;
    int res = isExist(con,name);
    if (res != -1) {
        for (int i = res; i < con->size; i++) {
            con->p[res] = con->p[res + 1];
        }
        cout << "删除成功" << endl;
        con->size--;
    }
    else {
        cout << "查无此人"<<endl;
    }
    system("pause");
}
//修改联系人函数
void updateContact(contact* con) {
    string name;
    cout << "输入要修改的联系人姓名查询" << endl;
    cin >> name;
