A decent code editor with wildcard / regular expression searches makes this quite easy to do.
You might not be able to write C++, but C++ and C are sufficiently similar that you should be able to get some idea of what it is doing, even if you don't know the detail.
Being able to take code in other languages and adapt to your own use is a skill worth having.
