cloc

When I test the cloc program, I faced some major problem.
Explanation:
I did the example program as follows.

int main()
{
printf("test \
//Testing//" );
}

After using the colc with options --strip-comments=c . I got new file
called a.c.c . Please refer the output.
int main()
{
printf("test
}

Anyone explain is this right ?

In this case, it should not remove the "//" which is surrounded on the
double quotes. This problem I faced in ruby program also. Please anybody
help me on this .
