If you are going to use that, you'd better include something like this first:

 

    if (NumberOfParameters > MAXIMUM_HARDERROR_PARAMETERS)

        NumberOfParameters = MAXIMUM_HARDERROR_PARAMETERS;


or make it

 

    for (i = 0; i < min( NumberOfParameters, MAXIMUM_HARDERROR_PARAMETERS ); i++)


or you might create more problems than you solve, unless you're 100% guarateed

you can never receive more than MAXIMUM_HARDERROR_PARAMETERS.

(This said without studying the actual problem at hand).
