C++ Help...Asignment due tomorrow...Friday!!!

[mturner64]

I have an assignment and I just and stuck and do not know where to start. The assignment is as follows:
____________________________________________

Write a C++ program that reads a file that holds certain stock information. The input data file looks something like:

**(the text file has 10 companies, each with abbreviaition and w/ 7 stock prices for each)**

International Business Machines
IBM
35.67
36.79
39.66
32.09
31.67
31.67
34.76
Epson Manufacturing Corporation
EPS
31.99
28.87
24.60
29.65
31.33
32.67
34.08
Company Name
3-letter stock exchange ID
Value for Sunday
Value for Monday
Value for Tuesday
Value for Wednesday
Value for Thursday
Value for Friday
Value for Saturday

The file will have no more than 10 records.

You will need to store the data in two separate (parallel) arrays. Store the company names and IDs in a 2-d array of type string. Store the values in a 2-d array of type float. That is, the string array should have dimensions [10][2] so it will have 10 rows and 2 columns numbered 0,1,2,3,4,5,6,7,8,9 and 0,1 respectively. The numeric array should have dimensions of [10][7] so it will have 10 rows and 7 columns, numbered 0,1,2,3,4,5,6,7,8,9 and 0,1,2,3,4,5,6 respectively.

Phase 1:
Your program should compute the 7-day average for each company’s stock and also the day’s total sum of values for each day. Use manipulators so your output is neat and lined up correctly. An example of your preliminary report follows:

Company ID Closing Price
----------------------------------------------------------
International Business Machines IBM 34.56
Epson Manufacturing Co. EPS 42.36
. . . . . . . . . . . . ... .....
Company Name XXX 99.99
----------------------------------------------------------
Total 999.99

I dont believe your doing anything with the file that your reading in?? It looks like you just have a statement saying what happens if it cant be read.

[mturner64]

I guess that is where I get frustrated...I do not know how to make the file read out like it is suppose to. I know I have to set up the arrays and make so loops but ????

[Ganon11]

Well, you know the file is written in the format

Full Name
3-Letter Abbrev
Value1
Value2
Value3
Value4
Value5
Value6
Value7

So, in a loop (until end of file), first get the full name and store it into a string, then store that string in company[i][0], where i is the number of times the loop has been executed. Then get the abbreviation and store it in company[i][1]. Next, in a second loop, get each of the 7 values and store them in quotes[i][j], where j is the number of values you have read.

[mturner64]

This was my other attempt:

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





int main()
{
ifstream inFile;
inFile.open("stock_data.txt");
if (inFile.fail())
{
cout << "Input file open failed.\n";
cout << "Call for help.\n";
exit (0);
}

string company[10][2] = {""};
int quotes[10][7] = {0.0};


cout << "This program displays the stock information for 10 companies.\n";
cout << "Company ID Monday Tuesday Wednesday Thursday Friday Saturday Sunday Average << endl;

for (int i = 0; i < 10; i++)
{
for (int j = 0; j < 2; j++)
{
cout << company[i][j] << endl
}
}
return 0;
}

***What does that look like in code?***

[Ganon11]

int i = 0; // 0 companies have been read
while (!inFile.eof()) { // While there is still data to read
   string compName, compAbbrev;
   // Get company name and abbrev from inFile
   company[i][0] = compName;
   company[i][1] = compAbbrev;
   for (int j = 0; j < 7; j++) {
      float price;
      // Get the float value from inFIle
      stocks[i][j] = price;
   }
   i++; // Increment the number of companies read so far
}

[mturner64]

}

THANK YOU FOR YOUR HELP....I WILL TRY IT AND LET YOU KNOW! :)

[mturner64]

So now what do I cout << ? (Here is the updated version)

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





int main()
{
ifstream inFile;
inFile.open("stock_data.txt");
if (inFile.fail())
{
cout << "Input file open failed.\n";
cout << "Call for help.\n";
exit (0);
}

string compName, compAbbrev;
company[i][0] = compName;
int quotes[i][1] = compAbbrev;
stocks[i][j] = price;

cout << "This program displays the stock information for 10 companies.\n";
cout << "Company ID Monday Tuesday Wednesday Thursday Friday Saturday Sunday Average.\n";

for (int j = 0; j < 7; j++)
{
float price;
cout <<
// Get the float value from inFile

}
i++; // Increment the number of companies read so far

return 0;
}
