here is my original code . I need to make a GUI for it. can you please make a GUI for me?
(C++ data strucs algorithms)
Thanks!

Explanation / Answer
made some changes. you haven't specified that in which language u wanted the GUI.
Fallowing program run properly just check it out
#include <iostream>
#include <cmath>
