trouble counting words in a file

sbcchelp (4)
the program is supposed to read a file specified by the user, and count the number of words. the program is to loop until the user types in 'quit'. The loop and exit functions are working, but my counter is always off by a couple of numbers. I know that my loop is not counting a word if there is no space after it, such as in the end of a file. The professor requires us to do the word count by comparing individual characters and not strings. the example data sets are below.

Also, when I run it on Dev-C++ (I know, but my teacher requires it), I get an error message:

"Assertion failed: infile, file (then lists the C: name)

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information."


Help?

I guess you miss the first and the last words.

<1> Remove line 40 and 53. Why to you read word into a string? This eats the first word.
<2> your loop-terminating condtition on line 24 condition has problem. As in data1, the last character is '.' (you won't get a white space character into currChar), thus the last word won't be counted. So you should take of 'end of file' condition into account.
