Question

Write a c++ program for the Sales Department to keep track of the monthly sales of its salespersons. The program shall perform the following tasks:

• Create a base class “Employees” with a protected variable “phone_no”
• Create a derived class “Sales” from the base class “Employees” with two public variables “emp_no” and “emp_name”
• Create a second level of derived class “Salesperson” from the derived class “Sales” with two public variables “location” and “monthly_sales”
• Create a function “employee_details” under the class “Salesperson” for obtaining the following information:
  • Employee number “emp_no”
  • Employee name “emp_name”
  • Employee phone number “phone_no”
  • Employee office location “location”
  • Monthly sales amount “monthly_sales”
• In the main() function, do the following:
  • Declare variables (int i, count, temp)
  • Create an object of Salesperson (ex. Salesperson man[50])
  • Prompt user to enter the number of salespersons
  • Create a for loop to loop through the number of salespersons to obtain the detailed info of the salesperson calling the “employee_details” function
  • Create a for loop to determine the salesperson with the highest sales
  • Print the results as below:
    • The highest monthly sales is : $100000
    • Congratulations!! Amy Ho! You are the top salesperson this month.
  • Create a for loop to determine the salesperson with the lowest sales
  • Print the results as below:
    • The lowest monthly sales is : $95876
    • Ramp Up, Brady Anderson. Your sales is the lowest this month.

Sample output:
