Expert Solution & Answer
Chapter 2, Problem 52E
Explanation of Solution
Hexadecimal number conversion
- For converting hexadecimal number “x434F4D50” into unsigned binary, then each hexadecimal digit is represented as a 4-bit binary string.
- Hence the unsigned binary number of “x434F4D50” is
0100 0011 0100 1111 0100 1101 0101 0000.
- The unsigned binary number of “x55544552” is
0101 0101 0101 0100 0100 0101 0101 0010
- The 1’s compliment of a hexadecimal number is calculated by converting the binary string into its one’s compliment and inverting all the bits that is 0 to 1 and 1 to 0.
- Hence the 1’s compliment of “x434F4D50” is
1011 1100 1011 0000 1011 0010 1010 1111
- The 1’s compliment of “x55544552” is
1010 1010 1010 1011 1011 1010 1010 1101
- The 2’s compliment of a number is calculated by inverting all bits and then adding number 1 to all bits.
- Hence the 2’s compliment of “x434F4D50” is
1011 1100 1011 0000 1011 0010 1011 0000
- The 2’s compliment of “x55544552” is
1010 1010 1010 1011 1011 1010 1010 1110
- For converting the binary string into IEEE format, the binary string is divided into three parts that is sign, exponent and fraction.
- The exponent and fraction part is then converted into decimal.
- The IEEE 754 floating point is calculated by
- For converting hexadecimal number “x434F4D50” into ASCII string,
- The binary value 01000011 represents hexadecimal 43

Question 1:
E-Hailing Bicycle Management System
Case Study:An e-hailing company that rents out bicycles needs a system to manage its bicycles, users, and borrowing process. Each user can borrow up to 2 bicycles at a time, specifically for families with children 18 years or below. The system must track the bicycles (name, make, type, and availability) and users (name, ID, and borrowed bicycles).
The company also wants to ensure that the system uses a multidimensional array to store information about the bicycles.
Requirements:
Add and View Bicycles:
Borrow Bicycles:
Return Bicycles
Display Borrowed Bicycles and Search for a bicycle
Create a menu-driven program to implement the above.
Sample Output:
Add Bicycle
View All Bicycles

Add a method called transfer () to the BankAccount class, that takes in an amount and
destinationAccount as input and transfer the funds from current account to destination
account.
This method should return the balance of the current account after the transfer, also should
check for the sufficient balance in current account before proceeding the transfer and if there is
insufficient balance return an error message "Insufficient balance".
Modify the BankAccount Test class, so that it calls the transfer () method and prints the
balance after transfer.
Make sure that the transfer() method updates the balance of both the current account
and the destination account.
• Create a public method called deposit() that takes in an amount of type double as input
and adds the amount to the current balance. This method should also return the updated
balance.
• Create another public method called withdraw() that takes in an amount of type double as
input, checks if the withdrawal amount is less than the current balance, and if so, subtracts
the amount from the balance. If the withdrawal amount is greater than the current balance,
the method should return an error message "Insufficient balance".
• Create a public method getAccountInfo() that returns the account information in the format
"Account Number: xxxxx, Account Holder: John Doe, Account Type: SAVINGS/CHECKING,
Balance: $xxxX.XX".
• Finally, create a constructor method that takes in the account number, account holder name,
initial balance and account type as input and initializes the corresponding instance variables.
In the BankAccount class, make sure to use the private access modifier for the
instance…
