//structures passing to functions by value
// create a Student structure that contains an ID number (integer), student name (string class),
//number of courses taken (integer) and GPA (double). Use a function getStudent to enter data for a student.
//Use a function showStudent to show the data. Pass the Student structure to the functions by VALUE, not by reference.
