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
 10/12/2018

 Unit Cost Extended
 Quantity Cost Market Cost Market Lower Cost
Mens Dept
 Suits 300 100.00 92.00 30000.00 27600.00
 Coats 200 60.00 65.00 12000.00 13000.00
 Shirts 1000 12.00 13.00 12000.00 13000.00
 Total $54000.00 $53600.00 $53600.00
Womens Dept
 Coats 185 184.00 200.00 34040.00 37000.00
 Shoes 600 40.00 30.00 24000.00 18000.00
 Total $112040.00 $108600.00 $108600.00
Girls Dept
 Shoes 200 30.00 34.00 6000.00 6800.00
 Total $118040.00 $115400.00 $115400.00
Boys Dept
 Total $118040.00 $115400.00 $115400.00
Total Inventory $393000.00

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(4) << cost << ".00 "
 << right << setw(3) << mkt << ".00 "
 << 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.
