Trying to get void getscore() to read from a file Please help!

[Diablo01]

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

// Function prototype
void getScore(int &);
void calcAverage(int , int, int, int, int);
int findLowest(int, int, int, int, int);
int grades(int, int, int, int, int);
int main()
{
ifstream grades;
grades.open("gr ades.txt");

int testScr1, testScr2, testScr3, testScr4, testScr5;


getScore(testSc r1);
getScore(testSc r2);
getScore(testSc r3);
getScore(testSc r4);
getScore(testSc r5);

calcAverage(tes tScr1, testScr2, testScr3, testScr4, testScr5);

return 0;
}

void getScore(int &score)
{



}

void calcAverage(int s1, int s2, int s3, int s4, int s5)
{
int sum;
int lowest;
double average;


lowest = findLowest(s1, s2, s3, s4, s5);

sum = s1 + s2 + s3 + s4 + s5 - lowest;
average = sum / 4.0;

cout << setw(4) << fixed << showpoint << setprecision(2) ;
cout << "The avergae of the four highest scores are: " << average << endl;
}

int findLowest(int s1, int s2, int s3, int s4, int s5)
{
int lowest = s1;

cout << "The lowest test score is: " << lowest << endl;

return lowest;
}
it is not reading from the file and returning required info. Please help!

This is the problem I cant figure out....void getscore() should read a score from a file and store it in reference parameter variable. This function should be called on for each of the 5 scores to be entered.

getScore() needs access to your input file. since you've created the fstream object in main, you could modify getScore's parameter list to take "grades" as a second argument.

Be sure the file argument is by reference to avoid making a copy. Otherwise you won't be using the file you opened.
