CASE STUDY – PAYROLL SYSTEM PHASE 5: ARRAY

The purpose of this phase is to expand the payroll system to display all employee information in a tabular form by including arrays.

A) Display company title and a header that labels the output in a tabular form. Input the first name and last name of an employee.

char firstname[100][10], lastname[100][15];

or you may use

#include

using namespace std;

string firstname[100], lastname[100];

int hw[100],empid[100];

Hint: You may want to use the following I/O manipulators.

#include , setw(15), setprecision(2) setiosflags(ios::fixed|ios::showpoint|ios::left)

B) Take advantage of arrays by breaking programs into separate units. Each unit should have a separate loop. (Do not use functions.)

Read all data into arrays

Compute all the overtimepays

Compute all the grosspays

Compute all the taxratesCompute all the netpays

Display all the arrays

C) Include separate functions to read in the data, compute the gross pay, tax rate, net pay, and overtime pay for all employees, and display.

Need to expand my payroll program, here is what I have so far-

#include <iostream>

using namespace std;

int main(){

    int numberofemployees;

    int employeeid, hoursworked;

    float hourlyrate, grosspay,taxrate,tax,netpay,overtimepay, overtimerate, overtime;

    while ( 1 ){

    if( grosspay <1000)

                        taxrate = 0.30;

            else

                        taxrate = 0.10;{

            if( hoursworked > 40)

                hourlyrate = hourlyrate * 1.5;{

        cout <<"ENTER THE EMPLOYEE ID:";

        cin >>employeeid;

        cout <<"ENTER THE HOURS WORKED:";

        cin >>hoursworked;

        cout <<"ENTER THE HOURLY RATE:";

        cin >>hourlyrate;

        grosspay=hoursworked*hourlyrate;

        tax=taxrate*grosspay;

        netpay=grosspay-tax;

        overtimerate=hourlyrate*1.5;

        overtime=hoursworked - 40;

        overtimepay=overtime*overtimerate;

        cout <<"EMPLOYEE ID IS "<<employeeid;

        cout <<"YOUR HOURS WORKED ARE "<<hoursworked;

        cout <<"YOUR HOURLY RATE IS "<<hourlyrate;

        cout <<"YOUR GROSSPAY IS "<<grosspay;

        cout <<"YOUR TAXRATE IS "<<taxrate;

        cout <<"YOUR NET PAY IS "<<netpay;

        cout <<"YOUR OVERTIME PAY IS "<<overtime;

        numberofemployees = numberofemployees + 1;

    }}}}
