Hello,
There was a typo in my code because of which it wasn't working.
scanf("%[\^n] ",text); should be scanf("%[^\n] ",text);
The carrot tells it take everything except a new line. The backslash
goes after the carrot.
The purpose of the program was to take some text and store it in
variable text and then display it.
Thanks,
