c++ is it worth preprocessor optimization for for loops while i < 1
Notational suggestion: if insisting on a bracketed controlled statement, favour
#if 0 &lt; repetitions
# if 1 &lt; repetitions
    for (int i = 0; i &lt; repetitions; i++)
# endif
    {
        CallFunc(functionPtr, otherParamaters …); // inline call to timed function
    }
#endif
