C++实现简单的通讯录管理系统
1. 功能设计
通讯录是一个可以记录亲人、好友信息的工具。
本代码主要利用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:
●添加联系人:向通讯录中添加新人，信息包括(姓名、性别、年龄、联系电话、家庭住址)最多记录1000人
●显示联系人:显示通讯录中所有联系人信息
●删除联系人:按照姓名进行删除指定联系人
●查找联系人:按照姓名查看指定联系人信息
●修改联系人:按照姓名重新修改指定联系人
●清空联系人:清空通讯录中所有信息
●退出通讯录:退出当前使用的通讯录
2.代码设计
1) 通讯录管理系统.cpp
#include<iostream>
#include<string>
#include<stdlib.h>
#define MAX 1000 //宏常量
using namespace std;
//1.设计联系人结构体
struct Person{
string m_name;
int m_sex; //1男；2女
int m_age;
string m_phone;
string m_addr;
};
//2.设计通讯录结构体
struct Addressbooks{
//保存联系人的数组
struct Person personArray[MAX];
//通讯录中当前记录的人的个数
int m_size;
};
bool positive(int n){//判断一个数是不是正数
if(n>0){
return 1;
}
else if(n==0){
return 1;
}
else{
return 0;
}
}
int length(string s){
int i = 0;
while(s[i]){
i++;
}
return i;
}
//添加联系人
void addPerson(Addressbooks * abs)
{
//1.判断通讯录是会否存满了
if(abs->m_size == MAX){
cout << "通讯录已经存满了，不可再存" <<endl;

}

//如果输入有误，重新输入

2. 添加联系人.cpp
#include<iostream>
#include<string>
#define MAX = 1000
using namespace std;
//1.设计联系人结构体
struct Person{
string m_name;
string m_sex;
int m_age;
string m_phone;
string m_adde;
};
//2.设计通讯录结构体
//3.main函数中创建通讯录
//4.封装添加联系人函数
//5.测试添加联系人功能
