Answer 1

My approach would be to first read in your list and add the words to an internal array. For example, words[0]="Hello", words[1]="you", etc.

Then, if each work is delimited by a space, you would begin reading in the file (or read up to a space) and then compare what was read against your array of words. If found, output each hex character using printf("%h", wordChar) and then get another word. If it's not in the array, copy the input "word" into a string and then print out the string.

proper what you may do is examine contained in the report as char utilising in.get() then once you may form forged the nature to int cout <
