    c++ arrays language-design language-features array-initialization
    When we initialize an array like this int a[5] = {0}, the compiler makes all 5 elements 0. That is really good, compact-initialization and useful feature. But I wonder why the compiler doesn’t initialize int a[5]={1} similarly? Why does it not make all 5 elements 1? Why the Standard doesn’t mandate i

    I just came across an interesting situation in Javascript. I have a class with a method that defines several objects using object-literal notation. Inside those objects, the this pointer is being used. From the behavior of the prog

    refactoring language-features language-design automated-refactoring
    What are common traits/properties of programming languages that facilitate (simplify) the development of widely automated source code analysis and re-engineering (transformation) tools?I am mostly thinking in terms of programming language features that make it easier to develop static analysis and refactoring tools (i.e. compare Java vs. C++, the former of which has better support for refactoring).In other words, a programming language that would be explicitly designed to provide support for automated static analysis and refactoring right from the beginnin

    javascript null language-features undefined
    In JavaScript, there are two values which basically say ‘I don’t exist’ – undefined and null.A property to which a programmer has not assigned anything will be undefined, but in order for a property to become null, null must be explicitly assigned to it.I once thought that there was a need for null because undefined is a primitive value and null an object. It’s not, even if typeof null will yield ‘object’: Actually, both are primitive values – which means nei

    c macros preprocessor language-features language-design
    I have written a little bit of C, and I can read it well enough to get a general idea of what it is doing, but every time I have encountered a macro it has thrown me completely. I end up having to remember what the macro is a and substitute it in my head as I read. The ones that I have encountered that were intuitive and easy to understand were always like little mini functions, so I always wondered why they werent
