My bank coursework

thx scuzzy

At uni i had to complete a bank simulation for my coursework. Handed it in today, thank god.
It was not hard but it was just effort, like most things to do with my education. I leave everything to the last minute so this is not the best i can do if i actually sat and went to lectures and started when they handed out the assignment.

anyway, here is my code:

#include <iostream>
#include <ctime>
#include <fstream>

class CAccount
{
public:
void OpenAccount()
{
std::cout << "Enter Balance: ";
std::cin >> iBalance;
bMortgage = 0;
dCreditLimit = 300;
std::cout << "(C)urrent or (J)unior Account?";
std::cin >> cAccountType;
while (cAccountType != 'C' && cAccountType != 'J')
{
std::cout << "Invalid Option" << std::endl;
std::cout << "(C)urrent or (J)unior Account?";
std::cin >> cAccountType;
}
}

void PrintAccount()
{
std::cout << std::endl;
std::cout << "Account Number: " << iAccountNumber << std::endl;
std::cout << "Balance: " << iBalance << std::endl;

}
