2. BankAccount Class Copy Constructor
 Add a copy constructor to the BankAccount class. This constructor should accept a
 BankAccount object as an argument. It should assign to the balance field the value in the
 argument’s balance field. As a result, the new object will be a copy of the argument object.
Solution
 Copy Constructor:
class BankAccount {
   
    private:
        double balance; // instance variable
   
    public:
        // copy constructor
        BankAccount(const BankAccount &other){
            balance = other.balance; // copying other\'s balance in current account
        }
 }
