Two languages which Pearl was meant to replace:

Perl was a combination of two languages “sh” and “awk” with more added features and hence it replaced these two languages.

“sh” was the first scripting language which contained a small set of commands. These commands were considered as system calls that performed file filtering or file management. Support for variables, control flow statements and functions made it a complete programming language.

“awk” was another scripting language which was initially used for generating reports but later became a general purpose language...

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 Borrow Bicycle Return…

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…
