You must create an array. Either this array must consist of your student number (Fig. 1 - Option 1) or you should take each element of the array from the user (Fig. 1 - Option 2). This should be the users choice. If the user wants to enter each element of the array, the number of elements in the array must be determined by the user. Then you must create two different functions. One of them must order the elements in the array in reverse order. The other one must order the elements in the array in descending order. Which function to use should still be the users choice.
