Will this regex be enough to remove C ++ multi-line comments?

Question

I need to parse some files in C ++, and to make it easier for me, I was thinking about deleting multi-line comments. I tried the following regular expression: /(\/\*.*?\*\/)/using a multi-line modifier, and it seems to work. Do you think there will be any case when he fails?

Answer 1

The following actions may harm you:

std::cout << "Printing some /* source code */" << std::endl;

This is a good example. Imagine the damage you could do if a line started a comment and didn't end? You can end up removing huge chunks of your code.

" " ( " ", "" ", ), . , .

Answer 4

Not trying to revive the old tides, but if I came across him, hey! As a more specific answer to the @Chris Lutz g ++ method:

g++ -fpreprocessed -E -P MyProgram.cpp -o NoComments.cpp

This will simply remove the comments and change the spaces by sending the new code to "NoComments.cpp" without any other crud.
