The ID (numeric part) and marks of each student can be entered. Once all the data is entered (with no sorting), the list of IDs and marks can be output in forward or reverse order (i.e. according to array index or the order you entered the data). Set a maximum number of 10 students to be entered including your own ID. Use only integer array(s). Show the output of the array in both orders.
