Chapter 1, Problem 18PS
Many contemporary languages allow two kinds of comments: one in which delimiters are used on both ends (multiple-line comments), and one in which a delimiter marks only the beginning of the comment (one-line comments). Discuss the advantages and disadvantages of each of these with respect to our criteria.

Many contemporary languages allow two kinds of comments: one inwhich delimiters are used on both ends (multiple-line comments), andone in which a delimiter marks only the beginning of the comment (oneline comments). Discuss the advantages and disadvantages of each ofthese with respect to our criteria.
Why is it essential for today's programming languages to provide both pass-by-value and pass-by-reference constructs? Why can't we merely choose between the two options? In your response, please explain both the advantages of having both and the reasons why it would be unwise to have just one or the other.
Why is it vital for modern programming languages to have both pass-by-value capabilities as well as pass-by-reference features? Why are we not only able to choose one of these two possibilities? It would be helpful if you could explain, in your answer, both the benefits of having both and the reasons why it would be foolish to have only one or the other.
