    double resistance[10] = {4.0, 8.5, 6.0, 7.35, 9.0, 15.3, 3.0, 5.4, 2.9, 4.8};
    calc_volts(volts, current, resistance);
    return 0;
Then just replace ???? with 10 and that should do the trick. You might want to display the results somewhere as well.

calc_volts() doesn't need to return anything but it will need to take the three arrays as parameters/arguments.
Ok thanks that makes sense. I actually do need to return the array that was filled and display the results in main(). If it's returning an array I can still use double for the return since all the values in the array will be doubles correct? If not how would I go about returning the array itself.
