reading input file

My program won't read the input file. I have the right names, so I know that is not the problem. I just don't know if I have to put the input file in the C++ or what. When I start the program, the black box just says to press a key and then the box goes away.

A code to check your input file to see if it open successfully!

if ( ! inputFile)
cout<<"Damn, open input file not OKie Dokie!"<<endl;
else
{ // process the input file here}

Hope ya get an idea!

Here is the code that I have right now:

Code:

---

# include <fstream>              // for file streams for input and output
# include <iomanip>              // for formatting manipulators
# include <string>              //
using namespace std;

int main ( ) {
       
        ifstream In("1.StockData.txt");        // Open the input file

        ofstream Out("Summary.txt");          // Open the output file

        string  CName,                          // Name of Customer
                    AccountNum,                    // Customer's Account Number
                    Date,                          // Date of Report
                    SName;                          // Name of the stock

        int    Shares,                          // Number of shares held
                  OpenDollar,                      // Opening price dollars
                  OpenCents,                      // Opening price cents
                  TotalOpen,                      // Total opening price
                  CloseDollar,                    // Closing price dollars
                  CloseCents,                      // Closing price cents
                  TotalClose,                      // Total closing price
                  UnitChange,                      // Gain or loss of each share
                  TotalChange;                    // Gain or loss of total value of shares

    double  PerChange;                    // Percentage change of value of a single share

        // Write the header information to the output file:
        Out << "Programmer: Danielle Barry" << endl;
        Out << "CS 1044 Simple Stock Trader" << endl;
        Out << endl;                  // Output a blank line for separation

        // Read the customer name:
        getline(In, CName);
       
        // Read account number and date:
        In >> AccountNum >> Date;

        // Write the data to the output file:
        Out << "Customer:"
                << setw(41) << CName
                << setw(17) << AccountNum
                << endl;
        Out << "Date:"
                << setw(11) << Date
                << endl;
}

Make sure the correct path where the input file and output file locate. if they locate in disk A: then
ifstream In("A:\\StockData.txt"); // Open the input file
ofstream Out("A:\\Summary.txt"); // Open the output

Also check files if open successfully
KingoftheWorld

rename this file

1.StockData.txt

by removing the first period. Then recompile. If still not effective determine location of that file. If it's not is same subdirectory as the cpp file for your driver program it will need to be moved there or you will need to use the full path name as per kingoftheworld's example.

Looks like you was ignored :(

Pleas use code tags, I don't even look at code if it isn't tagged
