Question

for a c++ assignment I need to create a program that reads 2 arrays into a file, which I have done below. What I do not understand how to do next is make a seoerate program that reads the data from the file and displays it.

#include "stdafx.h"

#include<iostream>

#include <fstream>

#include <string>

using namespace std;

const int NUM_LOCATIONS = 5;

const int NUM_COLS = 4;

void WriteData( const string[], const int[][NUM_COLS], int size );

int main()

{string locations[] = {"Albet","Deli","Gerry's","Johnny's","Moe's"};

int money [][NUM_COLS] =

{ {10000, 20000, 30000, 40000},

{5000, 4000, 5000, 6000},

{25000, 26000, 27000, 28000},

{36000, 2000, 33000, 34000},

542000, 43000, 74000, 45000}};

?

WriteData(companies, sales, NUM_LOCATIONS);

system("Pause");

return 0;

}

void WriteData( const string locations[], const int money[][NUM_COLS], int size)

{ofstream outFile;

outFile.open("c:\data\ex.txt");

for( int x = 0; x < size; ++x )

{

outFile << locations[x]<<" ";

for( int y = 0; y < NUM_COLS; ++y )

outFile << money[x][y]<<" ";

}

outFile.close();

}

Explanation / Answer

Dear,

Here is the code which reads data from file and displays on screen:

#include<iostream>

#include<string>

#include<fstream>

using namespace std;

const int NUM_LOCATIONS = 5;

const int NUM_COLS = 4;

void ReadData();

int main()

{

    ReadData();

     system("Pause");

     return 0;

}

void ReadData()

{

    ifstream inFile;

    string location;

    int money;

   inFile.open("c:\data\ex.txt");

    for( int x = 0; x < NUM_LOCATIONS ; ++x )

    {

          inFile >> location;

          cout << location<<" ";

          for( int y = 0; y < NUM_COLS; ++y )

           {

           inFile >> money;

           cout<< money<<" ";

          }

          cout<<endl;

    }

    inFile.close();

}
