INTRO TO UNIX COURSE

  1. Comments in C++ come in two forms: the block format started by a /* and ending with a */, often on different lines, and the inline format started by // and ended at the end of the line.

    What command would you give to list all lines of commented.cpp that contain inline comments?

  2. What command would you give to print (display on the screen) the contents of commented.cpp with all inline comments removed (and no other changes to the text)?

I need help with these grep commands.
