经历一系列会了忘会了忘我要把你记下来啦啦啦啦~不会忘啦~~~
写入文件:
void Card::Save(){ ofstream outfile("card.dat",ios::out|ios::app); if(!outfile) { cerr << "open error!" << endl; exit(1); } outfile<<name<<" "<<number<<" "<<sex<<" "<<position<<" "<<balance<<" "<<loss<<" "<<kind<<" "<<password<<endl; outfile.close(); }
ios::app 追加文件写入
从文件导入内存:
void Management::Output(){ ifstream CardFile("card.dat",ios::in); if(!CardFile) { //exit(1); return; } string name,sex,kind,position; int password; long num; bool loss; double balance; User *user=NULL; while(CardFile>>name>>num>>sex>>position>>balance>>loss>>kind>>password) { cout<<"姓名:"<<name<<endl; cout<<"号码:"<<num<<endl; cout<<"类别:"<<kind<<endl; cout<<"性别:"<<sex<<endl; cout<<"单位:"<<position<<endl; cout<<"余额:"<<balance<<endl; cout<<"是否挂失:"<<loss<<endl<<endl; user = new User(num,name,sex,kind,position,password,balance,loss); order.push_back(user); } CardFile.close();}
还有一个好玩的东西:cout << "\x07"<< "\x07"<< "\x07"<< "\x07";发粗声音!
