The program asks each traveller what their hotel is (the choices are the Seaview for which they need to join Queue 1, the Majestic for which they need to join Queue 4 and the Grand for which they need to join Queue 7) and tells them the right queue. There are 1330 travellers with the tour company and each will use the program as they arrive. After all have indicated their hotel, the program then prints the percentage in each hotel. * See image for an example run of the program. Percentages should be printed truncated to two decimal places. Do this using a method you write yourself that multiplies by 100, converts to an integer then divides by 100. * must make use of a counter-controlled for loop, be in procedural programming style (not OOP)
