Using the below code I am reading a .txt file and I can't get it to output properly. It either doesn't break the first input correctly (with all comma delimiters) or it doesn't break properly if I only use a comma delimiter after only the item name (2nd item in the text file).

Here the code:

#include <iostream>

#include <fstream>

using namespace std;



int main()

{

    ifstream inventoryFile;

    string itemType[100], itemName[100], matCost[100], manHours[100];

//  float matCost[100], manHours[100];

    string temp;



    inventoryFile.open("items2.txt");



    cout << endl << endl;



    if(!inventoryFile)

    {

        cout << "nnCan't read from file.n";

        exit(1);

    }

    int numItems=0;



    getline(inventoryFile, temp, ',');

    while(!inventoryFile.eof())

    {

        itemType[numItems] = temp;

        inventoryFile >> itemName[numItems];

        inventoryFile.ignore();

        inventoryFile >> matCost[numItems];

        inventoryFile.ignore();

        inventoryFile >> manHours[numItems];

        inventoryFile.ignore();

        numItems++;

        getline(inventoryFile, temp, ',');

    }



    for(int j=0; j<numItems; j++)

    {

        cout << "Item Type:t" << itemType[j] << endl;

        cout << "ITem Name:t" << itemName[j] << endl;

        cout << "Mats Cost:t" << matCost[j] << endl;

        cout << "Man Hours:t$" << manHours[j] << endl << endl; 

    }



    return 0;

}

The items.txt file is:

1, Xiphos, 7.46, 2

2, Dao, 3.45, 2.7

3, Jian, 2.31, 0.5

1, Rapier, 8.32, 2.3

2, Hook Sword, 2.11, 0.75

1, Panzerstecher, 2.23, 1.25

2, Kopis, 14.89, 2.3

3, Longsword, 5.43, 0.5

1, Tuck, 2.5, 15

1, Small Sword, 7.5, 2

3, Broadsword, 0.5, 0.25

The items2.txt file is:

1 Xiphos, 7.46 2

2 Dao, 3.45 2.7

3 Jian, 2.31 0.5

1 Rapier, 8.32 2.3

2 Hook Sword, 2.11 0.75

1 Panzerstecher, 2.23 1.25

2 Kopis, 14.89 2.3

3 Longsword, 5.43 0.5

1 Tuck, 2.5 15

1 Small Sword, 7.5 2

3 Broadsword, 0.5 0.25

This should work for the format in items2.txt.

string itemType[100], itemName[100];

float matCost[100], manHours[100];

//...

//getline(inventoryFile, temp, ',');

// get itemType and the whitespace after it

while(inventoryFile >> itemType[numItems] >> std::ws)

{

    std::getline(inventoryFile, itemName[numItems], ',');

    inventoryFile >> matCost[numItems] >> manHours[numItems];

    // don't count this entry if the stream is in a failed state

    if(inventoryFile.fail()) break;

    inventoryFile.ignore();

    ++numItems;

}

For items.txt this should work:

#include <cstdlib>

#include <fstream>

#include <iostream>

#include <sstream>

#include <vector>



using namespace std;



struct Row {

    int itemType;

    string itemName;

    float matCost;

    float manHours;

};



istream& operator>>(istream& in, Row& row){

    char comma;

    char firstCharOfName;

    in >> row.itemType >> comma >> firstCharOfName;

    in.putback(firstCharOfName);

    getline(in, row.itemName, ',');

    return in >> row.matCost >> comma >> row.manHours;

}



int main() {

    vector<Row> table;

    {

        ifstream inventoryFile("item.txt");

        string line;

        cout << "nn";



        if (!inventoryFile) {

            cerr << "nnCan't read from file.n";

            return EXIT_FAILURE;

        }

        while (getline(inventoryFile, line)) {

            // make room for next row

            istringstream iss(line);

            table.resize(table.size() + 1U);

            Row &newRow = table.back();

            iss >> newRow;

            if (!iss) {

                // skip row on error

                table.resize(table.size() - 1U);

            }

        }

    }



    for (int j = 0; j < table.size(); j++) {

        cout << "Item Type:t" << table[j].itemType << 'n'

             << "ITem Name:t" << table[j].itemName << 'n'

             << "Mats Cost:t$" << table[j].matCost << 'n'

             << "Man Hours:t" << table[j].manHours << "nn";

    }



    return EXIT_SUCCESS;

}

PS: Moved the $ to Mats Cost.
