    Post what you think are the answers, then we'll correct you.

    Sheesh, board abuse in the first degree.

    Angry

    I second Salem, why bother even trying to do the course you are on. You are either incapable or lazy. Read the site FAQ and don't expect help on questions like this.

    OK, here's one answer for you

    23. Have you heard of "mutable" keyword?
    Yes.

    Bye Bye vijayalakshmi, may you never get a programming job, you simply don't deserve one.

    Pathetic!

    If you ever get a programming job (which i highly doubt), what do you intend to do when you need to develop a real system? Post the specification to a forum and hope for the best?

    Personally, I prefer the inverse-faq game: I give an answer, and you supply the frequently-asked question.

    I'll start --- The answer is 42. What's the question?

    Bonus round: This has been a frequently-asked question since prehistoric times. Who was the person who originally published this answer, and in what literary work did it first appear?

    Regards,

    Dave

    Some interesting thoughts on what the question is can be found here.
    "Owners of dogs will have noticed that, if you provide them with food and water and shelter and affection, they will think you are god. Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."

    I kind of hoped that the Original Poster would do his own search (not necessarily for "the answer is 42", but for answers to his questions). Then you went and spilled the beans.

    Oh, well...

    Best regards,

    Salem made a nice start. Here's another one:
    25. Is there something that I can do in C and not in C++?
    Yes
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    Exectution??? Oh, I get it: execution.


    Well, I used to have a program like that, but I can't seem to find it...

    Well done. We'll crank through these questions eventually.

    18. How many lines of code you have written for a single program?
    4

    Well, with BASIC (that I taught myself in the third grade, on my RadioShack TRS-80), I found that deleting all comments would do it. It probably works the same with C and C++.

    Good call. You could also simply add a /* to the beginning of your program, and a */ to the end.

    I will say, "No, do it yourself."
