while loop help

[joeman]

the purpose of this program is to read a text file and count the total characters, the digits, puncuation, white spaces, etc, and then display the final count. right now i am trying to figure out what to put inside the while loop. it's not executing the current way i have it, and i've tried several other methods. i figure it has to be something along the lines of total number of characters (totalChar) is equal to all of the other characters added up. does anyone have any advice on what the condition inside the loop should be? (also i'm aware the displaying part at the end is not good, i'll fix that when i fix the loop)
