Need you to modify the above code so that the user will be prompted to either sort the integers as ascending or descending. The prompt for ascending should be "a" and descending should be "d". Please use proper commenting. Use the stdio.h library. Thank you in advance.

2) Modify the sort () function from Program 7.12 to take a third argument indicating whether the array is to be sorted in ascending or descending order. Then modify the sort() algorithm to correctly sort the array into indicated order
