Remember, anyone reading your post knows absolutely nothing whatsoever about you or your project apart from what you explicitly state in the post!
You post is meaningless because it lacks any context that would allow anyone to understand what you are talking about!
"i'm making one screen"
What does that mean? What "screen"? How are you "making" it? Are you talking about something displayed on your PC screen by the tools? Are you talking about an LCD screen in your target system? Or what??
"doing increment and decrement and shifting key operation"
What does that mean?
"i get '?' when i change the values"
Where do you get '?' ? What "values"? How do you "change" them?
"i'm using pointer for increment, decrement,shift operation"
How are you "using" this (these?) pointer(s)?
etc, etc,...
Please think about your post, and ask yourself: "will anyone with no other knowledge of my project be able to understand what I am talking about?"
