Comment Statements
The comment statements start from:
1) an asterisk (*) in the beginning of the line
2) a semicolon (;) in the beginning or middle of the line
If you find an asterisk (*) in a line, the whole line is the comment statement.
If you find a semicolon (;) in a line, the sentence after the semicolon is the comment statement.
No matter what a comment is, it will not affect program operation of function. Comments are used to
explain data structures, program algorithms, etc.
Comment statements are an important structural element of documentation. You should add comments
that are detailed as possible to enhance program maintenance.
The example below shows comment statements.
