Why is the program skipping the first line of every new deptnum?

I am trying to read from a file that looks like:

1 Suits   0300 100 092

1 Coats   0200 060 065

1 Shirts  1000 012 013

2 Dresses 0400 060 065

2 Coats   0185 184 200

2 Shoes   0600 040 030

3 Jeans   0200 040 035

3 Shoes   0200 030 034

4 Jeans   0300 042 043

The deptnum is the first column.

And when I write to the other file I get:

                    Blinn Discount Apparel Company

                        Inventory Evaluation

It skipped Womens Dept -> Dresses, Girls Dept -> Jeans, and Boys Dept -> Jeans.

Here is my code:

#include <iostream>

#include <iomanip>

#include <fstream>



using namespace std;



int main()

{

ifstream inFile;

ofstream outFile;



int x = 1, deptnum, quant,cost,mkt,extcost,extmkt,totalcost = 0,totalmkt = 0,

lowcost,totalInv = 0;

char item [15];



inFile.open("blinn.dat");

outFile.open("blinn.dout");



if (!inFile)

    cout <<"ntt Can't open data file: blinn.datn";





    else {

    outFile <<"nt                    Blinn Discount Apparel Companyn";

    outFile <<"t                        Inventory Evaluationn";

    outFile <<"t                            10/12/2018n";

    outFile <<"ntttttt Unit Costttt    Extendedn";

    outFile <<"tt  Quantity     Cost    Market       Cost     Market     Lower Cost";



    while (x < 5)

    {

        if (x == 1)

            outFile << "nMens Dept";

        else if (x == 2)

            outFile << "nWomens Dept";

        else if (x == 3)

            outFile << "nGirls Dept";

        else if (x == 4)

            outFile << "nBoys Dept";

        else

            break;



        while (inFile >> deptnum >> item >> quant >> cost >> mkt)

        {



            if (deptnum == x){



            extcost = quant * cost;

            extmkt = quant * mkt;



            outFile << left << "n " << setw(7)<< item << "      "

                << right << setw(4)<< quant << "  "

                << right << setw(5) << extcost<< ".00  "

                << right << setw(5) << extmkt << ".00";



                totalcost += extcost;

                totalmkt += extmkt;



                if (totalcost > totalmkt)

                    lowcost = totalmkt;

                else

                    lowcost = totalcost;





            }else

                break;

                }



            outFile << right << "n  Totalttttt                 $" << totalcost << ".00 $"

                    << totalmkt << ".00    $"<< lowcost << ".00";



        x += 1;



            totalInv += lowcost;

    }

        }



outFile << "nTotal Inventorytttttt                        $"<< totalInv<< ".00";





inFile.close ();

outFile.close ();



    return 0;

}

What is wrong with my logic?

There is a problem with your logic:

if (deptnum == x) {

    // do something

}

else {

    break;

}

To achieve the else branch, you have already read a line that deptnum != x (the first line of every new deptnum) so at the next iterator, the current line is discarded by the next input line.
