Programming Logic and Design, 7eSolutions 8-Programming Logic and Design, 7th EditionChapter 8Exercises1.Design an application that accepts 10 numbers and displays them in descending order.Answer: A sample solution follows. Please note that students could either sort the array indescending order and display, or sort the array in ascending order and display the array inreverse order, which is done here. Flowchart:1
