    How many methods/ways are there taking input by using with pointer and dynamic memory? Input: 3 1 2 n k l 2 1 2 p 4 55 62 * # x (x is stop value, first input always integer) Example code: p=malloc(sizeof(int)); scanf("%d",&num_arrays); while(1) { scanf("%c",&(*(p+i))); if(*(p+i)=='x') break; ++i; } "3" is stored in num_arrays. The other input values are stored in pointer[array].

  • Double "!!" in Ruby [closed]

    - by Alex Maslakov
    Possible Duplicate: What does !! mean in ruby? Ruby, !! operator (a/k/a the double-bang) Sometimes I see a Ruby code like this def sent? !!@sent_at end It seems to be not logical. Is it necessary to use here double !? As far as I'm concerned, it might be just def sent? @sent_at end UPDATE: then what is the difference between these def sent? !!@sent_at end def sent? @sent_at.nil? end def sent? @sent_at == nil end

  • Do we really need high level languages? [closed]

    - by i_love_c
    Seeing the amount of softwares developed (and still being developed) in C and considering the fact that C currently tops the TIOBE chart, I have this one question for you all: Do we really need high level languages like C# or F# or Ruby? Don't you think these so-called high level languages are actually spoiling programmers and resulting in suboptimal and non-efficient softwares?

  • Learn another useful programming language [closed]

    - by Sebi
    I know this question was here a lot of times and can't be answered at all, but im not looking for a single name, but rather for an advice in my situation. I learned programming with Java and now I'm developing in Java for more or less 5 years (at the university) and I thinks my programming skills their are really ok/average. I have also small experience in C/C++ and C#. Now I have some spare time and I'd like to learn a new language or deepen the knowledge of Java/C/C++. But how to choose the right language to learn? I'd like to learn a language which will be usefull in the future concerning working in a software development business? I know there is no single answer, but I'm sure you could mention some languages that are more usefull than others.

  • Whys is pdf format used? [closed]

    - by dan_vitch
    I will admit that I am new to the tech/dev field. It seems to become a trend that every time I have to work with pdfs a part of me dies. Why is this format as ubiquitous as it seems to be? Is it just non-tech people that prefer pdfs?

  • Suspension of Gmail account [closed]

    - by Ifeanyi Agu
    I have a Joomla site with my gmail account (google apps) being used as the SMTP server for sending mails. I also have a newsletter component on this site. I tried sending newsletter to all my subscribers and I noticed that the SMTP server could not be connected to. I then checked the emails of my company and noticed that the one I used to set it up was suspended. I cannot really explain why Google suspended the email account. Please could anyone tell me if Google saw the mails that were being sent as spam.

  • Objective-measures of the expressiveness of programming languages [closed]

    - by Casebash
    I am very interested in the expressiveness of different languages. Everyone who has programmed in multiple languages knows that sometimes a language allows you to express concepts which you can't express in other languages. You can have all kinds of subjective discussion about this, but naturally it would be better to have an objective measure. There do actually exist objective measures. One is Turing-Completeness, which means that a language is capable of generating any output that could be generated by following a sequential set of steps. There are also other lesser levels of expressiveness such as Finite State Automata. Now, except for domain specific languages, pretty much all modern languages are Turing complete. It is therefore natural to ask the following question: Can we can define any other formal measures of expressiveness which are greater than Turing completeness? Now of course we can't define this by considering the output that a program can generate, as Turing machines can already produce the same output that any other program can. But there are definitely different levels in what concepts can be expressed - surely no-one would argue that assembly language is as powerful as a modern object oriented language like Python. You could use your assembly to write a Python interpreter, so clearly any accurate objective measure would have to exclude this possibility. This also causes a problem with trying to define the expressiveness using the minimum number of symbols. How exactly to do so is not clear and indeed appears extremely difficult, but we can't assume that just because we don't know how to solve a problem, that nobody know how to. It is also doesn't really make sense to demand a definition of expressiveness before answering the question - after all the whole point of this question is to obtain such a definition. I think that my explanation will be clear enough for anyone with a strong theoretical background in computer science to understand what I am looking for. If you do have such a background and you disagree, please comment why, but if you don't thats probably why you don't understand the question.
