//设计一个person类，从键盘输入每个人的姓名、身份证号、年龄、地址等数据，并将每个人的信息保存在目录//C:下的二进制文件person.dat中，然后将文件中的个人信息读出来，保存在vector类型的向量中并显示出来//Eg9-8.cpp#include"iostream"#include"vector"#include"string"#include"fstream"#include"stdlib.h"using namespace std;class Person {public: Person() {}; Person(string _name, string _id, string _age, string _addr){ m_strName = _name; m_strId = _id; m_strAge = _age; m_strAddr = _addr; } void display() { cout << m_strName << "\t" << m_strId << "\t" << m_strAge << "\t" << m_strAddr << endl; }private: string m_strName; string m_strId; string m_strAge; string m_strAddr;};void main() { vector<Person>p; vector<Person>::iterator q; char ch; ofstream out("c:\\person.dat", ios::out | ios::app | ios::binary); string name; string id; string age; string addr; cout << "-----输入个人档案-----" << endl << endl; do { cout << "姓名:"; cin >> name; cout << "身份证号:"; cin >> id; cout << "年龄:"; cin >> age; cout << "地址:"; cin >> addr; Person s1(name, id, age, addr); //调用构造函数创建一个对象s1 out.write((char*)&s1,sizeof(s1));//函数write()一次插入n个字节到输出流中，即一次写入n字节内容到文件中 cout << "Enter another person (y/n)?"; cin >> ch; } while (ch == 'y'); out.close(); fstream in("c:\\person.dat", ios::in | ios::binary); Person s2; /*do { in.read((char*)&s2, sizeof(s2)); p.push_back(s2); } while (!in.eof());*/ in.read((char*)&s2,sizeof(s2)); while (!in.eof()) { p.push_back(s2); in.read((char*)&s2, sizeof(s2)); } in.close(); cout << "/n-----输入个人档案-----" << endl << endl; //q = p.begin(), for(q = p.begin(); q != p.end(); q++) { (*q).display(); } system("pause");}
