how to stop function at end of document

[jacobgallipeau]

Hey guys. Quick question: How can I edit the getScores function to get it to stop when there are no more values in the data.txt file??

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

int getScores(int arr[]);

const int NUM = 100;

int main() {

    int score[NUM];
    int total;
    
    total = getScores(score);
    
    cout << total;
    
    return 0;
}

int getScores(int arr[])
{
    ifstream infile;
    infile.open("/Users/jacobgallipeau/Documents/data.txt");
    
    int test;
    int end = 100;
    int total = 0;
    for(int i=0;i<end;i++)
    {
        infile >> test;
        if(test > 0)
        {
            cout << test << endl;
            arr[i] = test;
            total++;
        }
        else{
            total = end;
        }
    }
    
    infile.close();
    return end;
}
