Derived/base find

[dummy101]

Hi guys,
I have this project to do, and approximately no idea how to do it. I can start it, but I honestly have only a slight grasp on how this program is supposed to function.
The directions are as follows-
Write A program that has a base class with has client information – private members : ACCOUNT NUMBER, NAME, TELEPHONE, DATE , BALANCE, quarterly percent RETURN (calculated) and a derived class with client NAME, ADDRESS, TELEPHONE. The derived class is needed because potential and past clients are included in the derived class.
Your program should be able find a client by name and by account number.
You r program should be able to calculate how long the person has been a client given the DATE.. The base class and derived class must be in a header file. Your program should be able have at least 20 clients.

I started thus far:

#include <iostream>
#include <string>
using namespace std;

class accntInfo{
private:
	int accNumber;
	string name;
	int tel;
	int date;
	int bal;
	int QPR;
};

class persInfo: public accntInfo {
private:

};

I know I how base and derived work, but how do I go about using it to fit the rules of what I have to do. Advise asap!

Worked some more:

#include <iostream>
#include <string>
using namespace std;

class accntInfo{
private:
	string accNumber;
	string name;
	int tel;
	int date;
	int bal;
	int QPR;
public:
	accntInfo(string a = "A1", string n = "AA", int t = 000000000,
		int date = 00, int bal = 000, int QPR = 0);
	void putAccNum(string an)
	{
		accNumber = an;
	}
	void putName(string nam)
	{
		name = nam;
	}
	void putTel(int telly)
	{
		tel = telly;
	}
	void putDate(int m, int d, int y)
	{
		int mRef = 1;
		int dRef = 1;
		int yRef = 00;
		int ref = 0;
		int today=m*30 + d + y*360
	}

};

class persInfo: public accntInfo {
private:

};

working again:
no errors but doesnt allow input for anything beyond telephone
and the output--
everything is like - 87932823434 (im approximating)


thanks
