The Strip Filter ow that you know a little bit about filters, let's use that technique with our N homework for this chapter, a comment-stripping filter. Upload the starter code your workspace. Here are the details of the problem. Write a filter function named strip that removes C++ com- ments from input, sending the uncommented portion of the program to output. Your program should work with both sin- gle line (//) comments, and multi-line (/* */) comments. - A"/" sequence is ended by the first "r that is encountered. - Comment characters inside string literals "don't count" - Strings quotes may be escaped using an escape character. Single-line comments || may be included inside multi-line comments Because this is a filter, you program will read from cin and write to cout. 1. First Draft That looks pretty straightforward. Let's see what we need to do. - Include the header - Add the basic, unformatted I/O pattern to the function - Test the function with make test When you test it, you'll see that the function simply echoes every character input to out- put; this is the same echo filter presented in the chapter. To strip out the comments, we'll have to only print a character as long as it is not part of a C++ comment, in other words, we'll have to filter out the comment parts!
