- Comment about the program should be enclosed within /* */.
- Any number of comments can be written at any place in the program. For example, a comment can be written before the statement, after the statement or within the statement as shown below:
/* formula */ si = p * n * r / 100 ;
si = p * n * r / 100 ;
/* formula */
si = p * n * r / /* formula */ 100 ;
- The normal language rules do not apply to text written within /* .. */. Thus we can type this text in small case, capital or a combination. This is because the comments are solely given for the understanding of the programmer or the fellow programmers and are completely ignored by the compiler
- Comments cannot be nested.
For example,
/* Cal of SI /* Author sam date 01/01/2002 */ */ is invalid.
- A comment can be split over more than one line, as in,
/* This is a
jazzy
comment */
Notes: Often programmers seem to ignore writing of comments. But when a team is building big software well commented code is almost essential for other team members to understand it.
