is there exception handeling in this code?

No, there is no exception handling in this code. The code does not include any try-catch blocks or error checking for user input conversion. If an exception occurs during the conversion of user input to integers or doubles, the program will crash. It is recommended to add exception handling to handle any potential errors and provide a better user experience.
