Question

C++

Problem Specification:

You are to write a program that will define a structure consisting of the following data members, “fields”:

name

hours worked

hourly rate

Use a structure to implement the following:

You will use a function to read the name, hours and rate, passing them by reference to the main function.

You will use a function to print. This function prints each data member on a separate line followed by the grosspay - a local variable that gets its value by calling another function that will return the product of hours and rate.

Use a class to implement the same problem solution:

You must include a null constructor, and destructor.

You must not use inline function, must declare functions in the class declaration section, and then implement them.

Input to the program consists of:

name

hours worked

hourly rate

Your output should be a report like follows:

Employee Name:         Jim Donavan

Hours worked:                                                 40.00

Hourly Rate:                                              $     9.75

Explanation / Answer

Your question is little confusing. So, I have implemented it in two ways. One using c type structure, and another using class.

First, using structure:

#include <iostream>
#include <string>
using namespace std;

struct Employee {
   string name;
   int hrsWorked;
   float hrlyRate;
};

void readData(string&, int&, float&);
void printData(Employee e);
float calProduct(int, float);

int main() {
   Employee emp;

   readData(emp.name, emp.hrsWorked, emp.hrlyRate);

   printData(emp);

   return 0;
}

void readData(string& name, int& workHrs, float& rate) {
   cout << "Enter the name of employee: ";
   cin >> name;

   cout << "Enter the number of hours worked: ";
   cin >> workHrs;

   cout << "Enter the hourly rate: ";
   cin >> rate;
}

void printData(Employee e) {
   cout << "Employee Name: " << e.name << endl;
   cout << "Hours Worked: " << e.hrsWorked << endl;
   cout << "Hourly Rate: $" << e.hrlyRate << endl;
  
   float grosspay = calProduct(e.hrsWorked, e.hrlyRate);
   cout << "Grosspay: " << grosspay << endl;
}

float calProduct(int hrs, float rate) {
   return hrs * rate;
}
  
  

Following is using class:

#include <iostream>
#include <string>
using namespace std;

float calProduct(int hrs, float rate) {
   return hrs * rate;
}

class Employee {
   string name;
   int hrsWorked;
   float hrlyRate;

public:
   Employee(): hrsWorked(0), hrlyRate(0.0)
   {
   }

   Employee(string name, int hrs, float rate)
   {
       this->name = name;
       hrsWorked = hrs;
       hrlyRate = rate;
   }

   void readData(string name, int hrs, float rate);
   void printData();  

   ~Employee()
   {
   }
};

void Employee :: readData(string name, int hrs, float rate)
{
   this->name = name;
   hrsWorked = hrs;
   hrlyRate = rate;

}

void Employee :: printData()
{
   cout << "Employee Name: " << name << endl;
   cout << "Hours Worked: " << hrsWorked << endl;
   cout << "Hourly Rate: $" << hrlyRate << endl;
  
   float grosspay = calProduct(hrsWorked, hrlyRate);
   cout << "Grosspay: " << grosspay << endl;
}

int main()
{
   Employee emp;  

   string name;
   int workHrs;
   float rate;
  
   cout << "Enter the name of employee: ";
   cin >> name;

   cout << "Enter the number of hours worked: ";
   cin >> workHrs;

   cout << "Enter the hourly rate: ";
   cin >> rate;

   emp.readData(name, workHrs, rate);
  
   emp.printData();
  
   return 0;

}
