C++ supports comment format which is indicated by a II sign before the comment. In this case, the comment can proceed only till the end of current line. In case it is required to extend the comment beyond the current line, the comments should be preceded by the II symbol on subsequent lines also.
C++ supports the C comment format also where the beginning of a comment is marked by a symbol /* and the end of the comment is marked by */. In this case, the comment can proceed beyond one line also.
