    Pass the array to the function, then modify the array in the function. If you are using a container instead, pass the container by reference.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Side note: if you used functors instead of function pointers, then you could return a vector from the functor and hopefully the compiler will optimize it.
