License Plate Manager

A C++ based license plate manager that contains Illinois state license plates and basic identifying information for their respective owners. The manager will be able to store new license plates received through either manual entry or random generation as well as update information belonging to existing license plates. Users will be able to look up a license plate number through manual input of the number or an image input.

Features

• Ability to generate valid, non-duplicate license plate numbers in ascending order from a given starting point.
• Ability to save and load a csv data file containing license plates information.
• Ability to look up and update license plates by providing either driver’s full name, or their license plate number.
• Print the list of license plates in ascending order alphabetically by the driver’s last name.
• Ability to scan an image of a license plate.
