Notes in program and right format if possible, thanks. You can use any of the sorting searches like bubble or selection search or QuickSort since this is the section we are working on.
P.S This was the question I was given, I can't edit it to give more detail and I can't edit the outputs needed to have anything else because those are non editable and so are the given files.
For the above mentioned Program i had use directory path to my "D" Drive. So Assuming that my files is in "D" drive i am sharing my work.
