    For Loop

    I'm reading the book by Herbert Schildt called C++ From The Ground Up (3rd Ed). The thing that I dislike about this book, and it's something that stands out, is the fact that in almost every example he uses a For loop. I'm now trying to understand Arrays and Pointers (bloody hard pointers are) and there are For loops scattered all over the place. Are For loops really that useful? Sure, I understand it depends on the situation. I mean when I do things I stay away from For loops and just put a i++ or something at the end of a while or do while loop.

    Maybe it's just my dislike of For loops or ability to find easier to understand ways of doing Herbet's examples but I'd like to hear what actual coders think about this loop.

    Well Im not really good with C++ but I like for loops, I find use for them in almost every program I make, although they arent that advanced.

    HS has way too much red ink to ever stand as a credible author of technical subjects IMO.
    It takes a special kind of author to get their own jargon entry.

    The main problem is, readers confuse an easy read with being a good book, but if it teaches you the wrong thing, you're hosed and you don't even know it.

    Arrays and for loops kinda go together
    If you have
    int array[N];

    The natural way of accessing all the elements is
    for ( i = 0 ; i < N ; i++ ) array[i] = i;
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    It's perfectly normal to find for loops widely used, there's nothing unusual about the fact that Schildt appears to use them a lot in the book you mention; they are indeed very useful. Why is it that you don't like them? Either way, I wouldn't worry, in time you'll probably find that you use them often yourself without even thinking about it.

    I use for loops everyday. Very useful, esp with data structures.
