Output not showing

ITStudent101 (11)
I am trying to run following code with exp.txt input data file that has following data:

101 Allen Ron H S 38.00 15.00 0.00 179.45
200 Will Karr H S 50.00 20.00 0.00 300.50
302 Reba James S S 40.00 21.50 60000.00 250.00
409 Mike King S M 52.00 40.13 30000.00 450.00
109 Mark Jeff S S 34.00 80.30 70000.00 550.40

It's compiling without any error but when run - no output showing. Can anyone tell me what could be wrong?

There are 9 fields in this line. 

 
 
while(fin>>aemployeeid>>afname>>alname>>apaystat>>amaritalstatus>>ahoursworked>>areghourlyrate)


Is only trying to read 7 fields. You aren't reading the final 2 numbers. Also, you are testing for 'h' and 's' - whilst the file has 'H' and 'S'. h is not the same as H !
ITStudent101 (11)
I have changed the input data as follows. Also changed the order of fields in source code, but still output not showing.

101 Allen Ron h s 38.00 20.00
200 Will Karr h s 50.00 30.00
302 Reba James s s 40.00 10.50
409 Mike King s m 52.00 30000.00
109 Mark Jeff s s 34.00 70000.00

Write your own code, don't try and google your way through this by "finding" code then asking others to fix whatever mess you found/made.
seeplus (6495)
but still output not showing.


Does this code compile without errors? When I compile with VS2019 I get an error at line 18 as fname and lname are type char * - which isn't supported as standard.
ITStudent101 (11)
@seeplus. It compiles without error. I am using C++ Dev. Type of fname and lname are *char because those are array for pointer.

salem c (2893). Did not know that testing a online code for learning is called "stealing". This code is not only here, but many other places online. As far as I know this forum is for learning - if you do not know answer, then do not spoil other peoples learning with your lecture.

You need to fix a few things:

temp.cpp: In function 'int main()':
temp.cpp:199:51: warning: variable 'netpays' set but not used [-Wunused-but-set-variable]
 double ahoursworked, areghourlyrate, minnp,maxnp, netpays[8];
                                                   ^~~~~~~
temp.cpp: In member function 'virtual double payroll::findgrosspay()':
temp.cpp:86:1: warning: control reaches end of non-void function [-Wreturn-type]
 }//findgrosspay
 ^
temp.cpp: In member function 'virtual double salaried::findgrosspay()':
temp.cpp:62:1: warning: control reaches end of non-void function [-Wreturn-type]
 };//findgrosspay
 ^
temp.cpp: In member function 'virtual double hourly::findgrosspay()':
temp.cpp:51:1: warning: control reaches end of non-void function [-Wreturn-type]
 };//findgrosspay


Are you saying that things like employeeid are a single char? char employeeid


Please add indentation and do something about the line length.

Actually, the offence is probably plagiarism.

@salem c knows his stuff, probably writes C++ for a living. Lastchance & seeplus too.
