    Evaluation of nested loops

    Hello, All

    Another semester is upon us. I will teach C Programming at my college again this semester (as well as Java and C++)

    I am looking for tips and tricks to show my students how to evaluate nested loops like


    for (etc,,)
    for (etc)

    I like to show how the code actually does work by tracing throught the code. AS you know it can get confusing quickly.

    I thought somewhere here or on another board someone posted a good shortcut for evaluating nested loops.

    I have tried google. Not much there to help.

    Thanks for the ideas Mr. C

    You mean you want something like:
    Code:
    int main(void)
    {
      int i, j;
    
      for(i = 0;i < 5;++i)
        for(j = 0;j < 5;++j)
          printf("%d %d\n", i, j);
    }
    ? I'm confused as to what you're looking for.
    If you understand what you're doing, you're not learning anything.

    Well iterating through all the elements of a 2D array (or a matrix) is one example
    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.
