Question

c++ only

Design a class representing an Employee. The employee would have at least these private fields (Variables): name: string (char array) ID: string (char array) salary: float Type: string (char array) All the variables except for the salary should have their respective setters and getters, and the class should have two constructors, one is the default constructor and the other constructor initializes the name,ID and type of employee with valid user input. The class should have the following additional functions

1. ​float getSalary(float rate,int hoursworked) ​​that would return the employee’s monthly salary according to the rate and the weekly hoursworked. The employee’s salary is calculated as follows ​​rate* hoursworked*4. If the type of employee is “CEO” the salary will be multiplied by 2. If the type is “senior” the salary will be multiplied by 1.5 and if it’s a “standard” employee, the salary will remain the same, however the salary shouldn’t be less than 1000 in any case.

2. ​​void printEmployee()​​ which would print all of the employee’s information.​Note that if the user tries to set the type of Employee with any value other than “CEO”, “senior” or “standard” the class should set it to “unknown”.

Write a main to test your functions by creating an array of 3 employees. Your program should take the name,ID and type of each employee from the user, calculate their salary and display all of their information.

Code:

#include<iostream>
using namespace std;
class Employee
{
   string name;
   string id;
   float salary;
   string type;
   public:
       Employee()
       {
           salary=0;
           type="unkown";
       }
       Employee(string name, string id, string type)
       {
           this->name=name;this->id=id;this->type=type;
       }
       string getName()//getters
       {
           return name;
       }
       string getID()
       {
           return id;
       }
       string getType()
       {
           return type;
       }
       void setName(string name)//setters
       {
           this->name=name;
       }
       void setID(string id)
       {
           this->id=id;
       }
       void setType(string type)
       {
           if(type!="CEO" && type!="senior" && type!="standard")//not a known type
           {
               this->type="unkown";
           }
           else this->type=type;
       }
       float getSalary(float rate, int hoursworked)
       {
           salary=rate*hoursworked*4;
           if(type=="CEO") salary *= 2;
           else if(type=="senior") salary *= 1.5;
          
           return salary;
       }
       void printEmployee()
       {
           cout<<"Employee name: "<<name<<endl;
           cout<<"Employee ID: "<<id<<endl;
           cout<<"Employee type: "<<type<<endl;
           cout<<"Employee salary: "<<salary<<endl;
       }
};
int main()
{
   Employee employee[3];//create objects
   string name,id,type;float salary,rate,hours;
   for(int i=0;i<3;i++)
   {
       cout<<"Enter name of employee "<<i+1<<endl;//read from user and call respective methods
       cin>>name;employee[i].setName(name);
       cout<<"Enter id of employee "<<i+1<<endl;
       cin>>id;employee[i].setID(id);
       cout<<"Enter type of employee "<<i+1<<endl;
       cin>>type;employee[i].setType(type);
       while(1)
       {
           cout<<"Enter rate and hours worked by employee "<<i+1<<endl;
           cin>>rate>>hours;
           salary = employee[i].getSalary(rate,hours);
           if(salary < 1000)//invalid details, prompt user to enter again
           {
               cout<<"salary cannot be less than 1000. Please enter again"<<endl;
           }
           else break;
       }
   }
   cout<<"Employee details:"<<endl;
   for(int i=0;i<3;i++)
   {
       employee[i].printEmployee();
   }
   return 0;
}

Output:
