By ‘display’ problem, do you mean the issue that the entire code is not displaying in the screen - i.e. the text isn’t wrapped?
That’s the only thing I can think of because, yeah, like the above posters said, your code in that screenshot looks fine.
If your question is about text wrapping… I’m pretty new to CSIDE so I’m not sure if it has a text wrap feature 
But, I know there are other applications where you can enable this!
E.g. abc editor (see this thread: Coding apps for android? - #4 by Silverstone for more information), where it seems that they allow for text to be wrapped without compromising the ease of finding errors.
