Alright....this is a mess, but it works (compikes) correctly....how would I create a function (probably using "switch") to return a grade based on the averages found in CalculateAvg?

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
using namespace std;

double CalculateAvg (ifstream& students, string studentid[60], string fname[60], string lname[60],
					int Q1[60], int Q2[60], int Q3[60], int MidTerm[60], int Q4[60], 
					int Q5[60], int Q6[60], int Final[60], int i);
double FindLargest(ifstream& students, string studentid[60], string fname[60], string lname[60], 
					 int Q1[60], int Q2[60], int Q3[60], int MidTerm[60], int Q4[60], int Q5[60], 
					 int Q6[60], int Final[60],int i);
char grade(double CalculateAvg (ifstream& students, string studentid[60], string fname[60], string lname[60],

You can't really use a switch statement based on averages. Its better to use a series of if statements so that you can gest ranges of values

if( average > 90)
   return 'A';
else if( average > 80 )
   return 'B';
// etc etc

How can I import them using the average1, average1a, average1b...etc from the previous function until I can clean it up?

would it be like this

char calcGrade(double average1&, double average1a&....)

pop in a variable to get that value for use in the subsequent function call

double avgstore;
..... Q6[i] << setw(8) << Final[i] << (avgstore = CalculateAvg (students, id, fname, lname, Q1, Q2, Q3, MidTerm, Q4, Q5, Q6, Final, i));
     cout <<calcGrade(avgstore);   (try it tacked onto the end of the first cout just in case, I wasn't sure if it would be evaluated in the right order)

same for out <<

Are you saying that the avgstore is found in the main program? So, I would decalre is as: double avgstore; , and then my function would be like this:

double calcGrade(double avgstore)
{
   if (avgstore > 90)
     cout << 'A';
   else if (avgstore > 80)
     cout << 'A'

 etc....
}

You can call it whatever you want in the function, but yes I meant back in main keep an intermediate variable of your average function output and then feed that back into your grade function. I was just saying don't put them all on the same line because I'm not 100% sure if the grade function will be called before the other comes back with the value.

And I'm guessing that I messed up when saying "cout << 'A' " since the double function has to return a value...right?

Yes, and your function should return a char. Sry was trying to make sure you got things in the right place in main()

Yes, all the stuff in the main works just as you said...thanks! I'm not sure how return a char in my double function....would I be better served turning the function into a "char calcGrade(avgstore)"?

yes and putting return 'A'; etc. within your statements

if (avgstore > 90)
    return 'A';
else if (avgstore >80)
    return 'B';
...
else
    return 'F';

Ok....I got that working, but now it won't allow me to have some space between the numerical avg values, and the char grade. This is my output:

Press any key to continue . . .

and this is the code:

cout << left << setw(13) << studentid[i] << setw(12) << fname[i] << setw(12) << lname[i] << setw(7)
					<< Q1[i] << setw(7) << Q2[i] << setw(7) << Q3[i] << setw(7) << MidTerm[i] << setw(8)
					<< Q4[i] << setw(7) << Q5[i] << setw(8) << Q6[i] << setw(8) << Final[i] << 
					(avgstore = CalculateAvg (students, id, fname, lname, Q1, Q2, Q3, MidTerm, Q4, Q5, Q6, Final, i)) <<
				    setw(12) << calcGrade(avgstore);

even with the "setw(12)" there are no spaces....

You don't have a setw call in front of your calculateaverage. It's possible your grade, since it is left biased is bumping up against the average. Otherwise you can pop a few spaces in between with <<" "<< along your cout chain

you did it again jonsca! Thanks for all your help!
