I turned this in for my programming fundamentals class for our second
exam. I am a c++ newb, this is my first class I've taken. I got a good
grade on this project I'm just wondering if there is a better and more
efficient way to write this program.
//This program calculates the users Gross Pay and subtracts the tax
based off of Marital Status
//and the number of exemptions they select
#include <iostream>
#include <iomanip>
#include <string>
#include <stdlib.h>
using namespace std;
int main()
{
string FirstName; //Holds the user inputed First Name
string LastName; //Holds the user inputed Last Name
char MaritalStatus; //Holds the user inputed value for Marital
Status
double HoursWorked; //Holds the user inputed value of Hours Worked
double HourlyRate; //Hodls the user inputed value of Hourly Rate
double GrossPay; //Calculates and holds the users inputed value for
Gross Pay
double FederalTax; //Holds the calculations for calculating
FederalTax
double StateTax; //Holds the calculations for calculating StateTax
int NumExemptions; //Holds the user inputed value for Number of
Exemptions
