In the following code a single class is given i want to break into more classes and use concept oop e.g inheritance but do not mess p logic thank you , C++

#include #include #include #include

using namespace std;

char mainMenu(); void createAccount(); // User creates own username/password to and is stored in accounts.txt char bankingMenu(); class bank{ // Class is used in order to carry the variable bal through void functions int bal; // Balance, running total used in functions public : void deposit(void); // Will add money to the bal variable void withdraw(void); // Will subtract withdraw from bal void login(void); // Login achieved by using the accounts.txt file to check for username/password match void displayBalance(); void ShowTransHist();}; // Gets transaction history from the file path string and display int main() {

char choice; bank account; while (choice != 'q' || choice != 'Q') { choice = mainMenu(); if (choice == 'q' || choice == 'Q'){ cout << "Thanks for stopping by Justin's Bank!"; break;} // I use break a lot in this program.
