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.

- 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_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_forwardAs noted above, OOP in any language has some significant advantages. For the following questions, assume the role of a junior developer in a company that is creating a new PHP web application. The company has a few small PHP web apps, but they've been largely developed in isolation by individual developers who have followed mainly procedural programming techniques. This project will be the first large PHP project for the company, so it will be worked on by a team of developers, including yourself. There are also thoughts that this application may provide some core functionality that other, future applications may be able to use as well. In your original post, answer the following: How will using OOP techniques in the development of this application benefit the idea that the application will be creating some core functionality that may be of use to other applications? If the team is reluctant to adopt OOP techniques and wants to go with a more procedural approach that they're familiar…arrow_forward
- One characteristic of programming languages that varies widely from language to language is how parameters are passed. Among ALGOL, Pascal, Ada, C, C++, Java, and C#, no two languages pass parameters in exactly the same way. Among these languages, choose the one that you believe has adopted the best approach to parameter passing. Defend your decision by outlining the advantages of the approach of the language that you chose and the disadvantages of the approaches taken by other languages.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_forwardShould automatic type conversion be included in a programming language? Why or why not? Support your answer with an example from an appropriate programming language.arrow_forward
- Why 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_forwardI would be really thankful if you could help me out with the details. I am really confused about this assignment. And please don't copy other answers to here.arrow_forwardSome compilers perform all semantic checks and intermediate code generation in action routines. Others use action routines to build a syntax tree and then perform semantic checks and intermediate code generation in separate traversals of the syntax tree. Discuss the tradeoffs between these two strategies.arrow_forward
