Question
Rewrite the code below that reads employee data from a file (hourly wage, id number, and name) using an array of employee records. Update the hourly wage then output a formatted report.
o The input file is named wages.in.
o The output file must be named wages.rpt.
o For each function make sure you are passing properly the parameters by value or by reference as is appropriate.
o You must define and use global constants for:
• the maximum number of employee records to be read (up to 50) and
• minimum wage ($11.20/hour)
o You must define and use a struct named Employee. This type must have three members, a double to store the hourly wage, an int to store the idNo, and a string to store the employee’s name.
o You must use and define the following three functions; you may define more functions if you find it useful to do so.
• loadArraysFromFile
Parameters: an ifstream connected to the input file, an Employee array for the employee records.
Return: int – the number of employee records read
Read the employee records into the array of Employee.
• newHourlyWage
Parameters: an Employee (this is NOT an array)
Return: double – the new hourly wage
Determine the new hourly wage using the following method, in the given order.
If the wage is less than minimum wage change it to minimum wage.
If the id number starts with a 1 or 2 the employee gets a 2% raise
If the id number starts with a 3 or 4 the employee gets a 2% raise then an extra 5¢/hour.
If the id number starts with a 5 or 6 the employee gets a 4% raise then an extra 5¢/hour.
If the id number starts with a 7 the employee gets a 5% raise then an extra 5¢/hour.
If the id number starts with a 8 the employee gets a 5% raise then an extra 10¢/hour.
If the id number starts with a 9 the employee gets a raise of 50¢/hour.
The hourly wage must be ROUNDED to 2 decimal places before it is returned.
• writeReport
Parameters: an ofstream connected to the output, an Employee array, an int storing the number of employee records read.
Return: none
Print the report to the output file formatted as seen in the picture below.
Here is the code that needs to be modifed with struct statements:
#include
#include
#include
using namespace std;
const int MAX_EMPLOYEES=100;
const double MINIMUM_WAGE=11.20;
// function prototypes
int loadArraysFromFile(ifstream&,double[],int[],string[]);
double newHourlyWage(int,double);
void writeReport(ofstream&,const int[],const string[],const double[],int);
int main()
{
ifstream fin; // the input stream for the file wages.in
double employeeWage[MAX_EMPLOYEES]; // the list of employee wages
int employeeIdNo[MAX_EMPLOYEES]; // the list of employee numbers
string employeeName[MAX_EMPLOYEES]; // the list of employee names
int numEmployees=0; //the number of employee records found in the file
ofstream fout; // the output stream for the file, wages.rpt
fin.open("wages.in");
numEmployees=loadArraysFromFile(fin,employeeWage,employeeIdNo,employeeName);
fin.close();
for(int i=0;i
{
employeeWage[i]=newHourlyWage(employeeIdNo[i],employeeWage[i]);
}
fout.open("wages.rpt");
writeReport(fout,employeeIdNo,employeeName,employeeWage,numEmployees);
fout.close();
return 0;
}
int loadArraysFromFile(ifstream& fin,double wageList[],int idNoList[],string nameList[])
{
int numFound=0; // the number of employee records found in the file
for(numFound=0;numFound
{
fin >> wageList[numFound] >> idNoList[numFound];
getline(fin,nameList[numFound]);
}
return numFound;
}
double newHourlyWage(int idNo,double wage)
{
if(wage < MINIMUM_WAGE)
wage = MINIMUM_WAGE;
switch (idNo/1000)
{
case 1: case 2:
wage = wage * 1.02;
break;
case 3: case 4:
wage = wage*1.02 + 0.05;
break;
case 5: case 6:
wage = wage*1.04 + 0.05;
break;
case 7:
wage = wage*1.05 + 0.05;
break;
case 8:
wage = wage*1.05 + 0.10;
break;
case 9:
wage += 0.50;
break;
}
return static_cast(wage*100+0.5)/100.0;
}
void writeReport(ofstream& fout,const int idNoList[],const string nameList[],
const double wageList[],int length)
{
fout << " WAGE REPORT" << endl << endl
<< "ID NUMBER NAME HOURLY WAGE" << endl
<< "==================================================" << endl;
for(int i=0;i
fout << setw(7) << right << idNoList[i] << " "
<< setw(30) << left << nameList[i]
<< setw(10) << right << fixed << setprecision(2)
<< showpoint << wageList[i] << endl;
fout << endl << "Report Ends" << endl;
}
