In the above code i have used an array to input a string and convert it into ASCII decimal values and its reverse.I want to know in place of a string how can i take a file as an input to the array and the process gets executed for the whole of the file.

  • ...so the question is "how can I populate an array from a file"? There's rather a lot of unnecessary content for that -- we generally ask that questions be *minimal*, cut down to the shortest code necessary to illustrate the question; see http://stackoverflow.com/help/mcve – Charles Duffy Apr 02 '17 at 16:02
  • (BTW, you might try running through http://shellcheck.net/ -- there's quite a number of quoting bugs here). – Charles Duffy Apr 02 '17 at 16:03
