Output i get in command prompt

Enter your command :
exit
command exit, text Part └ command Length 4 command in the array
inside exit
Text found
exit should not be followed by a string

I don't understand what the L part is.

  • As this is both an incomplete, unformatted and way too long code, I don't really want to read it. But having weird characters in the output is often indicating an improperly terminated string somewhere. – Eugene Sh. May 31 '22 at 20:01
  • thanks for pointing out at least what i should look for. – Nikos Xatzichristidis May 31 '22 at 20:06

  • Whatever you have stored in the `textpart` variable is being interpreted as that character according to whatever encoding your terminal is using. – Alexander May 31 '22 at 20:41
  • Your loop that copies to `textpart` is repeatedly overwritring it. What's the point of that? Did you mean to concatenate them? – Barmar May 31 '22 at 20:42
  • When the command is `exit`, there's nothing in `textpart`, since it doesn't have any parameters. – Barmar May 31 '22 at 20:47
  • I didn't think about it . Thanks for the help. The above code is inside a while loop and I want to break the Input in two parts cmd and text part according to what the command is I check the text part below the Code above I probably should use strcpy instead for or at least that's what am thinking right now – Nikos Xatzichristidis May 31 '22 at 20:49
