Ex. 1.

• Input a real number representing the amount in dollars that a customer receives as the check in a restaurant.
• Then the program should ask the user if the service was good, and read his answer in a character as a 'y' or a 'n'.
• If the answer is 'y', the program must compute the tip as 20% of the amount, otherwise as 15%. Compute the total amount to be paid and output the result.
• Declare the percentages (15 and 20) as constants.
• Can you compute the result so that it has only 2 decimals (representing the cents)?

Ex. 2. Once the program is working, execute it step by step using the debugger.
