Help with Updated Program

[katalinaisland]

Hello,

So below is a code I have written; however, it has some specifications that are not being met and I am unsure what I am supposed to change.
1. Both the size of the array (a constant) and the array itself must be declared locally inside of int main().

2. Each option in the menu must simply call a function. Each function must at minimum pass in the array and the size of the array. You must list all function prototypes above int main () and all function definitions must appear after int main().

My Code:

#include<iostream>
#include<fstream>
#include<string>

using namespace std;
long int scores [10];//defining the score array


void readingscores();
void printscores(long int * scores);
void greatest(long int * scores);
void smallest( long int * scores);
void average (long int * scores);
void entry (long int * scores);
void readFile();

void menu () {
    int choice;
    cout <<" ---------------------------------------------------\n";
    cout <<"1-D ARRAY PROCESSING MENU OPTIONS\n";
    cout<<"---------------------------------------------------\n";
    cout<< "1. Read in 10 scores from user.\n";
    cout<<"2. Read in 10 scores from the file, scores.txt.\n";
    cout<<"3. Print all scores.\n";
    cout<<"4. Print the highest score.\n";
    cout<<"5. Print the lowest score.\n";
    cout<<"6. Print the average score.\n";
    cout<<"7. Print one score (give its entry number)\n";
    cout<<"8. Quit program\n";
    
    cout<<" Enter your choice:\n";
    cin >> choice;
    
    switch (choice) {
        case 1: readingscores(); break;
        case 2:readFile(); break;
        case 3: printscores(scores); break;
        case 4: greatest(scores); break;
        case 5: smallest(scores); break;
        case 6: average(scores); break;
        case 7: entry(scores); break;
        case 8:; break;
    }
    
}
int main ()
{
  
    menu();
   
    return 0;
}
void readingscores() {
    
    for (int i =0; i<= 9; i++) //filling up the array
    {
        std::cin >> scores [i];
        
    }
    menu();
}
void printscores( long int * scores) {
    for(int i=0; i<= 9; i++)
    {
        cout << scores [i];
    }menu();
    
}
void greatest(long int * scores){
  long  int great = scores[0];
    for (int i=0; i<= 9; i++)
    {
        if (scores[i+1]>= scores[i]) {
            great = scores[i+1];
        }
        
    }
        cout <<"The highest scores is:"<< great;
    menu();
}
void smallest(long int * scores){
    long int small = scores[0];
    for (int i=0; i<=9; i++)
    {
        if (scores[i]< small) {
            small = scores[i];
            
        }
        
    }
    cout <<"The lowest scores is:"<< small;
    menu();
}
void average(long int * scores){
    long int sum = 0;
    for (int i=0; i<=9; i++) {
        sum += scores [i];
    
    }
    cout << "The average score is:"<< sum/10;
    menu();
}

void entry(long int * scores){
  long  int number;
    cout <<" Enter your number (0-9)";
    cin >> number;
    cout << scores [number];
    menu();
}

void readFile() {
    ifstream myfile ("scores.txt");
    string line;
   
    if(myfile.is_open() )
    { int i=0;
        while(getline(myfile,line) && i<=9)
        {
            cout<<line<<"\n";
            
            scores [i]= stol(line);
            i++;
        }
        
        
       
        myfile.close();

You are supposed to declare your array inside main and pass it together with its size to the functions.

void readingscores(int scores[], int SIZE);
void printscores(int scores[], int SIZE);
void greatest(int scores[], int SIZE);
void smallest(int scores[], int SIZE);
void average (int scores[], int SIZE);
void entry (int scores[], int SIZE);
void readFile(int scores[], int SIZE);
void menu(int scores[], int SIZE);

int main ()
{
  const int SIZE = 10; 
  int scores[SIZE] = {0};

  menu(scores, SIZE);  
  
  return 0;
}
void menu (int scores[], int SIZE) {
    int choice;
    cout <<" ---------------------------------------------------\n";
    cout <<"1-D ARRAY PROCESSING MENU OPTIONS\n";
    cout<<"---------------------------------------------------\n";
    cout<< "1. Read in 10 scores from user.\n";
    cout<<"2. Read in 10 scores from the file, scores.txt.\n";
    cout<<"3. Print all scores.\n";
    cout<<"4. Print the highest score.\n";
    cout<<"5. Print the lowest score.\n";
    cout<<"6. Print the average score.\n";
    cout<<"7. Print one score (give its entry number)\n";
    cout<<"8. Quit program\n";
    
    cout<<" Enter your choice:\n";
    cin >> choice;
    
    switch (choice) {
        case 1: readingscores(scores, SIZE); 
        break;
    // and so on
    }
    
}

So basically what I am missing is:

void readingscores(int scores[], int SIZE);

and then from there I would alter that for the rest of the file and be okay?
