内容：
我是个初学者。。
有个难题想请大家帮帮忙。。

I need to create a programme with searching function.
这是一个病人资料存库。
我把病人的资料input了这个程式会把资料save进.txt file里。一个病人一个.txt file.
现在我必须
"create a searching function for viewing or retrieving patient's info. suggestion list should be printed out if the keyword searched has more than 1 compatible."

这是我的原本的sourcecode：

#include <iostream>
#include <string>
#include <fstream>
using namespace std;
class Hospital
{ public:
private:
};
class Patient:public Hospital
{
private:
string name, address, patient_contact_number, names_of_relatives_for_emergency;
string disease, medication, consultation_history, doctor;
string referal_letter, guarantee_letter, medic_card, insurance_cover,unknown, a;
public:
void personal_information();
void health_information();
void other_information();
void print_out();
void out_put ();
};
main()
{
Patient p1;
int num;
R:
system("cls");
cout<<"1. Add new patient's information.\n"
<<"2. View patient's information.\n"
<<"3. Exit.\n\n"
<<"Number :";
cin>>num;
system("cls");
if (num == 1)
{
p1.personal_information();
p1.health_information();
p1.other_information();
p1.out_put();
goto R;
system("cls");
}
else if (num == 2)
{
p1.print_out();
system("PAUSE");
system("cls");
goto R;
}
else if(num == 3)
{
exit(1);
}
else
{
cout<<"Invalid Input!"<<endl;
system("pause");
system("cls");
exit (1);
}
system("cls");
system("PAUSE");
system("cls");
return 0;}

cin>>a;
string FILENAME=a+"'s details.txt";
ifstream readingFile;
readingFile.open(FILENAME.c_str());
if (readingFile.fail())
{
cout<<FILENAME<<" opening failed.\a\a\a"<<endl;
system("pause");
exit (1);
}
else {readingFile>>name>>address>>patient_contact_number>>names_of_relatives_for_emergency>>disease>>medication>>consultation_history>>doctor>>referal_letter>>guarantee_letter>>medic_card>>insurance_cover;
