[Tutor] Building a simple text editor

[Asrarahmed Kadri]

Is it possible to make the utility like in vi, where the user keeps on
entering the data and when he hits ':wq', the work is saved and the
application exists.

I guess the use of standard input file would be applicable???

Thanks.
Regrds,
Asrar
