This is just a thought, but if you were replacing words with regex and you wanted to count how many words you replaced then how would you do that?

it might be easier to read (and write, and debug, etc) if you do a count-if though?

Why don't you use a stringstream or even strtok to split replace and count ?

I haven't heard of them.

Stringstreams are very useful so you should have a look at them.
For this task maybe stick with regex.
