- Please give the names of the various approaches of managing exceptions that are available.arrow_forwardC++ Program Use the FlightInfo class in the attached FlightInfo.h file for this assignment. Task 1: Modify the FlightInfo.h file to include the following (empty) Exception Classes. Invalid Direction Invalid Fuel Level Invalid Altitude Invalid Speed Modify the setter methods to throw an exception for invalid data. Note that these setters are void. They create exceptions instead of returning a value for invalid data. Task 2: Create a driver program that will instantiate a FlightInfo object. Driver Program steps. Prompt the user for the following inputs values Speed Direction Altitude Fuel Level Call the flightInfo's showAll() method. Catch these exceptions in the driver program and display a message anytime invalid data is given indicating the issue. The valid ranges are commented in the FlightInfo.h file. As usual, work on a small section like Invalid Direction and confirm that works as expected. Once that is good, the rest are very similar. 6 point Bonus. Create an additional…arrow_forwardin c++ Write a function named createOneStudent that will read in from the user the student info: id, name and gpa. It will use try-catch to handle the exception if the user provides a negative id or gpa that is out of bound (< 0.0 or > 4.0) by asking the user to re-enter them. It must provide the correct reason for the error and the actual error value. Then it will allow the user to try up to 3 times. This function will return the pointer of a newly created Student object or nullptr if the info is still incorrect. Note that this function can and will use cin and cout to read in values from the user. Here is an example of a run up to 3 times: Enter ID: -1 Enter GPA: 4.0 Enter name: John Smith Exception: negative id: -1 Enter ID: 1234 Enter GPA: 5.0 Enter name: John Smith Exception: out of bound gpa: 5.00 Enter ID: 1234 Enter GPA: 4.0 Enter name: John Smith ID(1234) NAME(John Smith) GPA(4.00) Here is an example of a run of 3 times and still not able to create it: Enter ID: 1234…arrow_forward
- PARTICIPATION ACTIVITY Arrange the following lines to make a program that determines when the number of people in a restaurant equals or exceeds 10 occupants. The program continually gets the number of people entering or leaving the restaurant. Ex: 2 means two people entered, and -3 means three people left. After each input, the program outputs the number of people in the restaurant. Once the number of people in the restaurant equals or exceeds 10, the program exits. If an Input MismatchException exception occurs, the program should get and discard a single string from input. Ex: The input "2 abc 8" should result in 10 occupants. Not all lines are used in the solution.
