    I tend to agree with you. However, the fact is that I have also
    created innumerable bugs by using sprintf format values with the wrong
    type of value. The function itoa() is not standard C or C++ and you
    have to remember about _itoa or _ultoa or all the other versions. And
    also "modern" programming tends to use all sorts of data items beyond
    char, int, or float.

    If you love good programming techniques, you will use the standard
    methods. If you love good performance, then diligent attention to
    your program design will yield far more effective results than relying
    on a few little tricks.
