Is it possible to pass back both a return variable & reference variable in one funct?

[GPXtC02]

As the title states.. is it possible to pass two variables back from a float function.. one through 'return variable' & the other through reference? If it is i will post the code.. but after hours of debugging & the program is still not recognizing the changed reference parameter (but the 'return variable' returns the correct value) this is the onlY conclusion i feel i can come too.
Appreciate a quick response! - Chris

Absolutely yes. If you can't get it to work right then post the code. Here is a common way to do it.

int foo( int& x)
{
   x = 123;
   return 1;
}

int main()
{
    int n = 0;
    int k = foo(n);
    cout << "n = " << n << "  k = " << k << "\n";
    return 0;
}

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

float GetHS(float[], int, int&);             //Proto-type.
float GetLS(float[], int, int&);             //Proto-type.

// /////// //
float GetHS(float(Scores)[], int nRecords, int& indexa) {       //Function computes the h
    float Highest=Scores[indexa];
    for(int a1=0; a1!=(nRecords+1); a1++)
        if(Highest<Scores[a1])
		{
            Highest=Scores[a1];
			indexa=a1;
		}
    return Highest;
}

// /////// //
float GetLS(float(Scores)[], int nRecords, int& indexb) {       //Function computes the l
	float Lowest=Scores[indexb];
    for(int a2=0; a2!=(nRecords+1); a2++)
		if(Lowest>Scores[a2]) 
		{
			Lowest=Scores[a2];
			indexb=indexb+a2;
		}
    return Lowest;
}

// //////////////////////////////// //
void main(void) {
    int IDs[50];                     
	float Scores[50];                         
      
	int i=0, argOne=0, argTwo=0;

	GetData(IDs, Scores, i);              
	int nRecords=i;             

	cout<<"The highest test score was "<<GetHS(Scores, nRecords, argOne)<<" by "<<IDs[argOne]<<"."<<endl; 
	cout<<"The lowest test score was "<<GetLS(Scores, nRecords, argTwo)<<" by "<<IDs[argTwo]<<"."<<endl; 
	cout<<"The average test score for the class is "<<GetAverage(Scores, nRecords)<<"."<<endl;
}

As the problem revolves the data i'm getting back from the GetLS & GetHS functions i took out the functions that are irrelevant to the problem i'm having but left enough to give a good idea of what i'm after. Problem is after going into GetLS or GetHS (both are similar.. one to find the highestscore & the other the lowest score) The score part comes out with the data declared in argOne&argTwo (0). i.e it never changed. when i put in a 'cout<<indexa' or '*b' too make sure it is finding the right data it tells me I am as it prints out the data i want.. problem is it never returns the index part (argOne & Two) which is what i want.

"<<GetLS(Scores, nRecords, argTwo)<<" the right data fine (using the 'return variable'
but "IDs[argTwo]" doesn't return the correct value.

in GetHS(), line 10, I assume nRecords is the number of valid entries in the array Scores. If that is true then line 12 is incorrect. Should be this: for(int a1=0; a1 < nRecords; a1++) because arrays are numbered from 0 up to but not including nRecords. Same is true of line 24.

lint 28: indexb=indexb+a2; << wrong. should be indexb = a2; lines 43, 44 and 45. Split those lines up something like below and see if that solves the problem, after correcting the above problems.

float x = GetHS(Scores, nRecords, argOne);
cout<<"The highest test score was "<<x<<" by "<<IDs[argOne]<<"."<<endl;

appreciate the help. the above simple syntax errors were the problem
