Structure sorting,searching with array

Define a structure that describes a hotel. It should have members that include the name, address, grade, average room charge and number of rooms.

Write a function to perform the following tasks.

i) To print all hotels details of a given grade in order of charges.
ii) To print hotel details with room charges less than given values.
