Overtime project

[verdell32]

This question is for Valmont. Would the pacheck.cpp help that you gave me; would it help with this one? Cause the output almost seems similiar I think we are just adding on the calculation of overtime?

CSIS 121 Introduction to Computer Science

Project OVERTIME




Write a program that does a payroll calculation for employees that get time and one/half for any work over 40 hours per week and double time for any work over 48 hours per week.



Interactive input:

Enter employee number: _

Enter hours worked : _



File input:
The employee’s employee number, name and pay rate are in a file called “MasterFile.dat”

Format of the data in the file:



employeeNumber ‘\t’ employeeName ‘\t’ payRate



employeeNumber is a 7 digit integer.

employeeName is a string with embedded blanks

payRate is a floating point value



Output format:

Employee Hours Pay Regular Premium Gross Net Federal State

Number Name Worked Rate Pay Pay Pay Pay Tax Tax

1234567 Joe Smith ##.# ##.## ###.## ###.## ###.## ###.## ###.## ###.##



Calculations
Federal tax is 33% of the gross pay

State tax is 6% of the gross pay



Exceptions:

If the file “MasterFile.dat” is not found or opened, display an error message and quit.



Validate the data read from the MasterFile. i.e. Make sure the employee number in the file matches the number entered interactively. If the employee numbers do not match, display an error message and quit.



Notes:

To declare a storage location for a persons’ name write this declaration:

char name[64];

:p

[Valmont]

I can't remember that file. What project was it?

[verdell32]

it was called pacheck.cpp, but I think this time we have to add the if and else statments in the code.

I think I have this one figured out but now I can't figure out how to line up the output correctly since I have added the 2 new entries(Regular pay and Premium pay)?

Output format:

Employee Hours Pay Regular Premium Gross Net Federal State

Number Name Worked Rate Pay Pay Pay Pay Tax Tax

1234567 Joe Smith ##.# ##.## ###.## ###.## ###.## ###.## ###.## ###.##

The output doesn't fit in a bash or console. I don't understand what your teachers wants. No matter how I fiddle, it always will look ugly.
And why is he learning an outdated style by the way?

[verdell32]

Like I said before in the paycheck project I finally figured it out and everything was even in the output; but with these new entries everything is off. If you know of a better way to make it all come out even; then please help me. I will use your method to make the out put even. At least this first class is over this week and then I move onto "Object-oriented programming".

Note: If you can help me with your style of output; then I still have to keep the "box" around the output. Sometime I think I should have started with a "Visual Basic Class" before I jumped into C++?

Do it with tabs then:

[verdell32]

First of all I would like to apologize but, my teacher sprung on us today that he wants the program to do something a little bit different. I really like the way that you got the stuff even. I say truly that I appreciate all the help you are giving me (Valmont) you help me through my first class. I only have two more projects (timeDiff and phonebill) thank God and then I will be moving on to Object oriented programming


1. User enter the employee number; then that will find the employee name and the employee pay rate

so in this program we are supposed to use the "while Loop" and the if/else statements.

This is the example that he gave us:

#include <iostream>
#include <fstream>

int main
int accountNum, searchItem;
char name[30]

cout << "Enter account number:";
cin >> searchItem;

ifstream accountFile("account.lst", iso::in);
accountFile>>accountNum; //primary input

while(!accountFile.eof() searchItem! =
accountNum){
accountFile.ignore(80; '\n' );
accountFile >> accountNum; //continuing input

}//endwh

if(searchItem == accountNum){
accountFile.getline(name, sizeof(name)-1);
cout << accountNum << " " << name << endl;

{else}
cout << "Account" << searchItem <<
"not found!" << endl;

}//endif
return 0
}//endmn

Thank you very much,
D.O.C.

This is not due to Monday(12-13-04). If you have anytime I would appreciate the help.

[Valmont]

So how is the *.lst file organized? His code does not convince me.

[verdell32]

I think he "*.lst" has something to do with a master.dat" file because when he showed us yesterday; he opened it up in Notepad and it had a "list of employee's numbers, payrate, etc.

[Valmont]

Oh, I see, the one like in your first post.

[verdell32]

Correct Now I have to figure out what to change/how to approach this?

[Valmont]

There are so many approaches. Here something that works. Perhaps you could fine more ways.

#include <iostream>
#include <string>

void wait_for_enter();

//Additional helper. Remove if not needed.
void reset_istream();

int main(int argc, char *argv[])
{
  ifstream theAccount("account.lst");
  if(!theAccount)
  {
    cout<<"ERROR! Reason: could not open or find file."<<endl;
    wait_for_enter();
    return -1;
  }
  
  cout<<"employee number: ";
  unsigned employeeNumber;
  cin>>employeeNumber;
  
  unsigned empNum;
  string employeeName;
  double payRate;
  bool b_found(false);
  // Assuming *.lst has this format (note \t): unsigned\tstring\tdouble
  while(theAccount>>empNum)
  {
    if(empNum == employeeNumber)
    {
      b_found = true;
      theAccount >> employeeName >> payRate;
      cout<<empNum<<endl;
      cout<<employeeName<<endl;
      cout<<payRate<<endl;
      break;
    }
    else
    {
      theAccount.ignore( numeric_limits<streamsize>::max(), '\n' );
    }
  }
  
  //Eof not reached but item not found either. So something must have gone wrong.
  if( !theAccount.eof() && b_found == false)
  {
    cout<<"ERROR! Reason: could not process the file properly."<<endl;
    cout<<"Terminating program..."<<endl;
    theAccount.close();
    wait_for_enter();
    return -1;
  }
  else if( b_found == false ) //All went O.K. but item has not been found.
  {
    cout<<"This employee number does not exist."<<endl;
  }
  
  theAccount.close();
  
  reset_istream();
  wait_for_enter();
  return 0;
}


//---------------------------------------------------

   if(cin.eof())
