The 4th deliverable is to create the program the makes the buy recommendation. It uses the class Stock to store and retrieve the stock information. I need to make this program compatible with my stocks class.
Program I need to change:
#include <iostream>
#include <cmath>
#include <fstream>
#include <iomanip>
#include <string>
#include <stdlib.h>
using namespace std;

int openDatafile(ifstream&,string [], float[], float[],
int[]); // opens the data file
void readData(ifstream &, string[], float[], float[], int[],
const int MAX, int&); // reads in the information from data
file
void getSymbol(ifstream&, string [], int); // reads in the
symbol
void getCurrent(ifstream&, float[], int); // reads in the
current price of the stock
void getBought(ifstream&, float[], int); // reads in the bought
price of the stock
void getShares(ifstream&, int[], int); // reads in the number
of shares owned
void outputResults(string[], float[], float[], int[], int&); //
output the possible buy stocks for user
int main () {
ifstream ifs;
const int MAX= 100; // 100 is max number of stocks that will be
read in from file
string s [MAX]; // gets the stock symbols
float c [MAX], b [MAX]; // gets the current price; gets the bought
price
int shares [MAX]; // gets the number of shares owned
openDatafile (ifs, s, c, b, shares);
int numberRead = 0;
readData(ifs, s, c, b, shares, MAX, numberRead);
outputResults (s, c, b,shares, numberRead);
return 0;
