Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit…
