Hi all,

I'm getting 6 errors from my code, stemming from two main reasons:

  • Expected identifier or '('
  • Use of undeclared identifier

I can't figure out what went wrong my code even after inspecting line by line.

Please consult and provide advice.

My code will be posted in the link below:


Many thanks in advance! :)

  • Fixed careless mistake on line 22, changed "isalpha" to "!isalpha". Sep 12 '18 at 5:38
  • add ) at the end of line 48 and 54. Sep 13 '18 at 8:49
  • use help50 command to easily get help on errors. Sep 13 '18 at 8:50
