Your program is working perfectly fine.I am not able to understand your logic clearly. What is that you are trying to do. You have normally written the while loop in such a way that it will be exited whenever the value of cont is other than 1. So at first the while loop satisfies and the user provides the input for "i".
But when you provide 1 or 2 for the switch case, the value const will be replaced with zero and then the execution goes to while. This will act as an infinite loop till the value of i tends to be other than 1 r 2 .
but if the value of i is other than 1 or 2, cont will be same and the while loop fails the second time.

root-tail
ROOTTAIL(1) General Commands Manual ROOTTAIL(1)NAME
root-tail - print text directly to X11 root window
SYNOPSIS
root-tail [-g|--geometry GEOMETRY] [-fn|--font FONTSPEC] [--color color] [--reload SEC COMMAND] [--shade] [--outline] [--minspace]
[--noflicker] [-f|--fork] [--reverse] [--whole] [--partial] [--update] [--cont STRING] [--wordwrap] [--justify] [--noinitial] [--frame]
[-id ID] [-i|--interval SECONDS] [-V] file1[,color[,desc]] [file2[,color[,desc]]]
DESCRIPTION
Displays a given file anywhere on your X11 root window, i.e. it is kind of tail -f for multiple files using your desktop background as out-
put window.
All non-option arguments on the command line are files to be logged. A null desc (example: "/var/log/messages,red,") will prevent the
printing of a description and the []'s.
General Options
--color COLOR
Use COLOR as default.
--font | -fn FONTSPEC
Use font FONTSPEC. This can be either a fixed width font like -fn fixed or any font using -fn '-*-*-*-*-*-*-*-*-*-*-*-*-*-*' with
the appropriate fields filled out (see xfontsel). Specifying a different FONTSPEC before each filename will cause each file to be
displayed in a different font.
-f | --fork
Forks to the background.
--reverse
Display the files in reverse order, with the newest lines at the top.
--whole
Only display whole lines. If the last line of a file doesn't yet end with a newline character then wait until it does before dis-
playing it. This is the default if more than one file is being displayed.
--partial
This is the opposite of the --whole option (see above). It displays lines even if they don't yet have a newline at the end. This is
the default if only one file is being displayed.
--update
Update partial lines 'in place' if they are still on the screen when they are updated in their files. Using --update automatically
turns on --partial.
--cont STRING
When partial lines are broken into two lines in the display, prefix the 2nd line with STRING. Defaults to "|| ". Specify the
"--whole" argument to ensure partial lines are never displayed, or specify "--update" to attempt to "repair" broken lines in-place.
--cont-color COLOR
Use COLOR when displaying the continuation string (as optionally specified with the --cont option above).
--wordwrap
The default behaviour is to fit as much as possible onto each line of output, even if this means splitting a word between one line
and the next. The --wordwrap argument splits lines at spaces if possible.
--justify
After wrapping long lines, attempt to justify the text to produce a smooth right-hand margin. Implies --wordwrap.
--reload SEC COMMAND
Re-display the file(s) and run COMMAND every SEC seconds. The default is to never re-display the file(s).
--shade
Add black shading to the font.
--outline
Add a black outline to the font (making redraws quite a bit slower).
--minspace
Use minimum linespace even when using shading or outlining. This might result in leftover pixels (dependign on font and logfile con-
tent).
--noflicker
Use slower but flicker-free update.
--noinitial
Don't display the end of the file(s) initially.
-id ID Use the given window ID for output instead of the root window.
-i | --interval SECONDS
Use the specified sleeping interval between checks instead of the default 2.4 seconds. Fractional values are OK.
-V Print version information.
--frame
Draw a frame around the selected area. This is useful when trying to find the perfect geometry.
EXAMPLE
root-tail -g 800x250+100+50 -font 10x20 /var/log/messages,green -font 12x24 /var/log/secure,red,'ALERT'
BUGS
Some desktop environments open a virtual root window and make it difficult to share it. If you cannot see anything after starting root-
tail, try to find a setting "allow programs on desktop" or similar, or manually specify a window id.
Should you happen to find any bugs please fix them and send me a diff.
