in language C: A travel agency asks you to develop an application that allows you to manage your travelers. A traveler is characterized by: - A login - A name - A first name - A number of trips - A set of trips, each trip is characterized by: - a destination - a travel date defined by three integers: day, month and year A) Define the necessary structures. B) Write a program that allows via a menu of: 1. Complete a table of n travelers. 2. Sort travelers' trips in ascending order of date. 3. View the travelers table (All fields).(display)
