Textbook Question
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.

Discuss the advantages and disadvantages of each ofthese with respect to our criteria.
Why are pass-by-value and pass-by-reference constructs required in modern programming languages? Why can't we just choose one of the two possibilities? Please describe the benefits of having both in your answer, as well as the reasons why it would be foolish 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.

- Why is it vital for today's programming languages to have both pass-by-value and pass-by-reference constructs? Why is it that we can't just choose one of these? Please address both the benefits of having both and the drawbacks of having either alone in your answer.arrow_forwardWhy is it important for modern programming languages to have both pass-by-value operations 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.arrow_forwardIs there any reason why modern programming languages can't do without pass-by-value and pass-by-reference constructs? Why is it that we can't just choose one of these? Please address the benefits of having both and the drawbacks of having either alone in your answer.arrow_forward
- Why is it necessary for programming languages to provide constructs such as pass-by-value and pass-by-reference? Why aren't we allowed to choose one? Kindly describe the advantages of having both, as well as the disadvantages of just having one.arrow_forwardWhy is it important in modern programming languages to include both pass-by-value & pass-by-reference? Why not just have one or the other? In your answer, describe the benefits of having each AND describe why it wouldn't be a good idea to have only one or the other.arrow_forwardWhy do modern programming languages need to support both value and reference passing? When deciding between these two alternatives, why is it so difficult to choose only one? Your solution should address both the positives of having both and the drawbacks of having either alone.arrow_forward
- Describe some design -trade--offs between efficiency and safety in some language you know.arrow_forwardWhich various types of programming paradigms are there? The question then is why there are so many diverse paradigms. Do you have no choice but to have them? Talk about it using your own words and putting your own spin on it.arrow_forwardDiscuss the concept of operator precedence and associativity in programming languages. Why is it important for understanding and writing correct code?arrow_forward
- A new language with a block structured syntax similar to Algol 60 uses either pass-by-reference or pass-by-value as a parameter passing mechanism, but you don’t know which. Design a test program you can use to find out which parameter passing method it uses and explain how the results of your program will enable you to detect the parameter passing mechanism.arrow_forwardWhy is it necessary to separate the Lexical and Syntax analysis phases? Discuss the importance of Intermediate Code Generation. Explain the aim and attributes of the Error handler as well.arrow_forwardHow about a rundown of the many types of programming paradigms? Then, why is it that there are so many paradigms? Is it necessary to have them? Use your own words to describe it.arrow_forward
