The last employee data does not show when compiling the code - c++

Question

I'm trying to obtain the data for the last employee Bob Hu. But for some reason, it doesn’t want to show up. Does anyone know what I'm doing wrong.? I try to put the calculation/display code into a function() and call it where you currently calculate/display the data and also after while() terminates. But I think I'm doing it wrong. Please help
This is my code.
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
void find_pay(string x)
{
ifstream inputFile;
string filename;
// Get the filename from the user.
cout << "Enter the filename: ";
cin >> filename;
// Open the file.
inputFile.open(filename);
// If the file successfully opened, process it.
if(inputFile.is_open())
{
string data_record,prev,data_name,data_hour;
double total = 0;
while(getline(inputFile,data_record))
{
data_name = data_record.substr(0,30);
data_hour = data_record.substr(31,2);
if(prev.compare(data_name)!= 0 )
{
//Calculate the gross pay, tax, net pay
float gross_pay = 18 * total;
float tax = (12 * gross_pay)/100;
float net_pay = gross_pay - tax;
if(total!= 0)
cout << "Employee:" << prev << "\n" "Total Hours: " << total << " Gross Pay: $ " << gross_pay << " Tax " << tax << " Net Pay: " << net_pay << endl;
data_name = data_record.substr(0,30);
prev = data_name;
total = 0;
}
else if(prev.compare(data_name)==0)
{
total += stod(data_hour);
}
}
//close the file
inputFile.close();
}
}
int main()
{
string filename;
find_pay(filename); //call the void
return 0;
}
This is the output that I got, as you see Bob Hu is missing
Enter the filename: /Users/normatacuri/Desktop/employeehours.txt
Employee:Jimmy Bucket
Total Hours: 26 Gross Pay: $ 468 Tax 56.16 Net Pay: 411.84
Employee:John Doe
Total Hours: 32 Gross Pay: $ 576 Tax 69.12 Net Pay: 506.88
Employee:Ann Doe
Total Hours: 20 Gross Pay: $ 360 Tax 43.2 Net Pay: 316.8
Employee:Mary Jones
Total Hours: 16 Gross Pay: $ 288 Tax 34.56 Net Pay: 253.44
Program ended with exit code: 0
This is the data on the file that I'm using..

I try to put the calculation/display code into a function() and call it where you currently calculate/display the data and also after while() terminates. But I think I'm doing it wrong.
You are right, you must have done it wrong, but your approach of handling the case also after while() terminates was good. Since you don't show this try, I can't say what you were doing wrong. But I can show you an alternative approach where the EOF case is also handled inside the loop - for this replacement of the while loop only a few statements have to be rearranged.
for (; ; )
{ bool f = (bool)getline(inputFile, data_record);
if (!f || prev.compare(data_name = data_record.substr(0, 30)) != 0)
{ // do this on EOF as well as new name
//Calculate the gross pay, tax, net pay
float gross_pay = 18 * total;
float tax = (12 * gross_pay)/100;
float net_pay = gross_pay - tax;
if (total != 0)
cout << "Employee:" << prev << "\n"
"Total Hours: " << total << " Gross Pay: $ " << gross_pay
<< " Tax " << tax << " Net Pay: " << net_pay << endl;
if (!f) break;
prev = data_name;
total = 0;
}
total += stod(data_hour = data_record.substr(31, 2));
}
