// Question 1
// Create a BankAccount class with the following :
// - A constructor that accept account holder's name, account number and balance
// - A deposit method that increases the balance
// - A withdraw method that decreases the balance, but only if there are sufficient funds 
// - A getBalance method that returns the current balance
