your removenextword() method greedy i.e. it's removing numbers well.

in implementation, first remove that's not letter before word, word , characters following word not letters removes id numbers well.

perhaps, should uncomment line , rename isletter() istoken().

 (ch >= '0') && (ch <= '9') ||  // allow numbers 

edit: please fix conditional check numbers. ch <= '1' incorrect.
