1-d arrays score analysis program

[ahofmann415]

I have most of the code i need written...i think. I am having trouble making it all come together and work fluidly. I want the menu to output and then the user inputs a menu number. I want that task to be performed and then return to the menu. I also need the scores.txt file to be used in the cases where the user does not enter them first, as a default. I also need to make sure the numbers entered are passed by every function. thank you.

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

void getNumbers();
void numFromFile();
void printAll();
void printHigh();
void printLow();
void printAvg();
void printOneScore();

int main()
{

int scores[10];
int menu;

cout << "-------------------------------------------------" << endl;
cout << "1-D ARRAY PROCESSING MENU OPTIONS" << endl;
cout << "-------------------------------------------------" << endl;
cout << endl;
cout << "1. Read in 10 scores from user."<< endl;
cout << "2. Read in 10 scores from the file, scores.txt." << endl;
cout << "3. Print all scores." << endl;
cout << "4. Print the highest score." << endl;
cout << "5. Print the lowest score." << endl;
cout << "6. Print the average score." << endl;
cout << "7. Print one score (give its entry number)." << endl;
cout << "8. quit program." << endl;
cout << endl;
cout << "Enter your choice: " ;
cin >> menu;
