/*
Write   a   program to  read    a   file    called  file.txt,   which   contains    an  arbitrary
number  of  characters. You have    to  create  a   new file    named   filea.txt   that    have
all the digits  in  file.txt    replaced    with    the symbol  *.
The text    file    can contain:    This file contains some random numbers like 1 and 3.
And can have other numbers like 4566 and 563454. A  sample  filea.txt,  created by  the program,
for the above   input,  is  shown   below:  This file contains some random numbers like * and *.
And can have other numbers like **** and ******.
