    After reading a few posts on this forum, it makes me remember some horrible code I have written before. (While I was a VB5 programmer) It also reminds me of some horrible code I've seen some other people write, like the following:

    private bool isValid(int testValue, int minValue, int maxValue)
    {
    for (int counter = minValue; counter <= maxValue; counter++)
    {
    if (testValue == counter)
    {
    return true;
    }
    else
    {
    if (counter == maxValue)
    {
    return false;
    }
    }
    }
    }

    To make matters worse, they then called this method a few hundred times with min and max Values of 0 and about 500.

      Hey, don't knock VB5... Back in the day, it was pretty amazing if you were too lazy/rushed to learn the MFC. As for the code... Wow... Nice one.

          Nice, that's a brilliant little horror. p.s. use <pre> tags around your code instead of <code> tags. <pre> tags will preserve the whitespace.

            I saw the following formatting masterpiece:

            int nTotalMinutes; // Total time expressed in minutes

            int nHours=0;
            int nMinutes=0;
            while (nTotalMinutes >= 60)
            {
            nTotalMinutes -= 60;
            nHours++;
            }
            printf("Time %d:%d\n", nHours, nMinutes);

            The above snippet only illustrates the concept because, if I remember well, the starting point were nTotalSeconds! :-D

                      In case you did not notice, the original code has a "bug". If maxValue is less than minValue, then the function may not return anything. In any case, your code is not equivalent to the original code because: isValid(1, 1, 0) returns true with the original code. isValid(1, 1, 0) returns false with your code. Releasing code without testing is dangerous, isn't it? :-D

                          No, the loop wouldn't be entered, so it would return... ummm... oh yeah, that's why it won't compile; "Not all code paths..."

                            Is that VB5 code? I was forced to write in VB6 once and the code you presented would not have compiled. I understand why this is a coding horror – who ever wrote it needs to find a new line of work. P.S. I am still having trouble believing what I am seeing.

                              the original code has a "bug". If maxValue is less than minValue

                              That may be true if the intent is to determine whether or not the test value "is between" the other two values; which is likely, but may not be the case. As to improving the efficiency of the routine... I've had bosses who would say, "It's always been that way, don't change it." And colleagues who would say, "It ain't broke, don't fix it." In one memorable case I bloody well did fix it, and the result was that the program took ten minutes to run rather than forty... and I was out of a job. Yes, I'd do it again.

                                I saw the following formatting masterpiece:

                                int nTotalMinutes; // Total time expressed in minutes

                                int nHours=0;
                                int nMinutes=0;
                                while (nTotalMinutes >= 60)
                                {
                                nTotalMinutes -= 60;
                                nHours++;
                                }
                                printf("Time %d:%d\n", nHours, nMinutes);

                                The above snippet only illustrates the concept because, if I remember well, the starting point were nTotalSeconds! :-D

                                    After reading a few posts on this forum, it makes me remember some horrible code I have written before. (While I was a VB5 programmer) It also reminds me of some horrible code I've seen some other people write, like the following:

                                    private bool isValid(int testValue, int minValue, int maxValue)
                                    {
                                    for (int counter = minValue; counter <= maxValue; counter++)
                                    {
                                    if (testValue == counter)
                                    {
                                    return true;
                                    }
                                    else
                                    {
                                    if (counter == maxValue)
                                    {
                                    return false;
                                    }
                                    }
                                    }
                                    }

                                    To make matters worse, they then called this method a few hundred times with min and max Values of 0 and about 500.

                                    took a long time to work out what that code actually does. I kept looking at it and thinking "No surely that's not it". Now i realise that that is the true horror of this creation. On top of that i can only guess the result of having testvalue > maxvalue but i guess as a private method it can expect sanitised input. wow, Russ
