the program bellow has a problem on "the search value method " when you run it, at the end when you are being asked to enter a search value, when you type a number which is not an integer like 3.2, 2.1, 4.52...., the program say element not found and the asks you if you want to search more (y,N), but then it stops and will not run any more, which means you can not type the answer to the question.

I need some help so that I will be able to type an answer to the question and continue with the search until i type "N" . which means the program should no stop all together but contiue.
