Question

In C++ please! Thanks!

Define a class Employee with data members as

• int employee_id – To store employee ID.
• String employee_name – To store the name of the employee.

Define class Salary which inherits Employee class and has the following characteristics

• Data members
  • String designation – To store employee designation.
  • double monthly_salary – To store salary of the employee.
• Methods
  • constructor Salary(int employee_id, String employee_name, String designation, double monthly_salary) – Invokes a superclass constructor and initialize data members.
  • void display() – To display details of employees whose earning is more than 20,000. Details of an employee should be separated by spaces.

Input
   3
   123
   John
   engineer
   40000
   124
   Emma
   Testing
   33000
   125
   White
   Trainee Engineer
   20000

   where,

• First line represents the number of employees whose details are provided.
• Second line represents employee ID.
• Third line represents employee name.
• Fourth line represents designation of the employee.
• Fifth line represents employee salary per month.
• The remaining lines represent the details of the remaining employees in the same format as given above.

Output
   123 John engineer 40000.0
   124 Emma Testing 33000.0

The output displayed details of employees who earn more than 20,000.

Code-

#include<bits/stdc++.h>
using namespace std;
class Employee{ //super class Employee
   public: //public data members and methods
       int employee_id;
       string employee_name;
       //constructor
       Employee(int employee_id,string employee_name){
       this->employee_id=employee_id;
       this->employee_name=employee_name;
       }
};
class Salary :public Employee { //inherits Employee class publically
   public:
   //Salary class data members
   string designation;
   double monthly_salary;
   //constructor of Salary class and calling constructor of parent class
   Salary(int employee_id, string employee_name, string designation, double monthly_salary):Employee(employee_id,employee_name){
   this->designation=designation;
   this->monthly_salary=monthly_salary;
   }
   //display function
   void display(){
   if(monthly_salary>20000){//if salary greather than 20000 then only display
   cout<<"Output is "<<employee_id<<" "<<employee_name<<" "<<designation<<" "<<monthly_salary<<endl;
   }
   }
};
int main(){
   int number_of_employees;
   cout<<"enter the number of employees";
   cin>>number_of_employees;
  
   int empid;
   string empname;
   string desig;
   double income;
  
   for(int i=0;i<number_of_employees;i++){
       cin>>empid>>empname>>desig>>income;
       Salary s(empid,empname,desig,income);// salary class object
       s.display();
   }
}

//note-i have removed space between Trainee and Engineer so that it can go to same data variable
