understanding call by reference functions

[allenowen]

I'm in a beginning level C++ course and I don't fully understand how call by reference parameter work. More to the point, how would they pass values to another function? I have a projectto work on that requires me to read data from a file, tally up number and pass these value to another function that will print out the results(it's a voter tally program). I'm not asking anyone to do this for me, but I need some insight.

Thanks for any help anyone can give me
