This question isn't really for any specific technology but more of general developer question. We all know from experience that things change. Frameworks evolve, new features are added and stuff gets removed. For example, how might a product using version 1.0 of the "ABC" framework adapt when version 2.0 comes along (ABC could be .NET...
Hello to everybody..and greetings from Greece I have a C program for an exercise and it has a strange issue The program runs just fine on VS 2005 but it crashes on DEV-C++ and the problem that the problem is that the exercise is always evaluated against DEV-C++ The program is about inserting nodes to a BST and this is where the problem ...
Java forbids operator overloading, but coming from C++ I do not see any reason for that. In languages where operator symbols are symbols as any other, same rules apply to "+" as to"plus" and there is no problem. So what is the point? Edit: To be more concrete, show me which disadvantage overloaded "+" may have over overloaded "equals". ...
Given a method that accepts as a parameter a certain supertype. Is there any way, within that method, to determine the actual class of the object that was passed to it? I.e. if a subtype of the allowable parameter was actually passed, is there a way to find out which type it is? If this isn't possible can someone explain why not (from ...
I was asked in an interview : how to convert 0 to 1 and 1 to 0. I answered : Simple if and switch Bit flipping. Are there any other approach? ...
I'm a java programmer and am trying to understand the difference between a method (java methods) and a function (such as in c++). I used to think that they are the same, just different naming conventions for different programming languages. But now that I know they are not, I am having trouble understanding the difference. I know that...
I couldn't find any question that directly applies to my query so I am posting this as a new question. If there is any existing discussion that may help me, please point it out and close the question. Question: I am going to do a presentation on C# coding guidelines but it is not supposed to limit to coding standards. So I have a roug...
I had some experience on programming languages like Java, C#, Scala as well as some lower level programming language like C, C++, Objective - C. My observation is that low level languages try separate out header files and implementation files while other higher level programming language never separate it out. Those languages use some i...
Hi! I do not really know if this is scientifically proven, but I've read in a book (It was a relatively modern AI book by Peter Norvig) that second-order logical programming could be more expressive than existing first-order languages. The question is: Is it statistically/symbolically proven that higher-order predicate logics exceed fi...
I'm currently working on the topic of programming-languages and interpreter-design. I have already created several programming languages but couldn't reach my goal so far: Create a programming-language which focuses on giving the programmer a good feeling when writing code in it. It should just be fun and/or interesting and in no case a...
This has been bugging me every since I started to use Python - in PHP you have this ability to use a string as a key in an array. PHP calls these associative arrays. Python calls these dictionaries. Does anyone know of a premade chart that will let me see what the different terminology is in different languages. For example: PHP ...
How can you tell a normal person (i.e. your mom, grand mom, your little brother) how was the first program was written? They ask this question a lot and I really can't give an answer they can understand. ...
I need to create a simple program/utility to parse a txt file (deleting blank rows, concatenating lines, etc) that runs in Windows XP and can be called from a Windows command line. What programming language/environment best fits this type of application? Thanks, I hope I'm not being vague. ...
I'm trying to import data from a csv file to some html code to use it in a graph I have already coded. I'm trying to use PHP and fgetcsv to create arrays for each separate piece of data to use PHP to put it into the html code. I know how to open the csv file and to print it using PHP, and how to print each separate row, but not each piec...
Hi, I'm writing a virtual machine in C just for fun. Lame, I know, but luckily I'm on SO so hopefully no one will make fun :) I wrote a really quick'n'dirty VM that reads lines of (my own) ASM and does stuff. Right now, I only have 3 instructions: add, jmp, end. All is well and it's actually pretty cool being able to feed lines (doing i...
I'm a CS student and has rare experience from the enterprise software industry. When I'm reading about enterprise software platforms, I mostly read about these two: Java Enterprise Edition, JavaEE .NET and Windows Communication Foundation By "enterprise software platforms" I mean frameworks and application servers with support for th...
Hello, What is the best way in C++ to use std::map in loops ? dynamically allocated stack allocated Code: for(int i=0;i<3;i++) { std::map<int,int>* m = new std::map<int,int>; //or ... std::map<int,int> m; } ...
UPDATE: Perhaps this wasn't clear from my original post, but I'm mainly interested in knowing a best practice for how to structure javascript code while building a solution, not simply learning how to use APIs (though that is certainly important). I need to add functionality to a web site and our team has decided to approach the solutio...
Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<...
Hi! A newbie question. Do languages like e.g. Ruby (if running MRI, I mean not compiled to byte-code) run actually parsed everytime when an execution of, e.g., method or loop body is needed? I mean, to execute a loop, you need to parse its body N times? I just always thought that all these programs are being parsed one time at the boot...
