Question

write a c++ program.

A real estate broker sets fees for selling properties according to the property type as shown in the table. The broker wants you to write a program that prompts the user for the broker type, sale price of the property and the property code. If the user enters an invalid property code or broker code, the program should display an appropriate message and end the program. Allow the user to enter uppercase and lowercase letters. If the sale price of the property is greater than or equal to P15,000,000.00, an additional 2.5% is added to the commission rate. The program should display the gross commission (sale price times commission rate) and net commission(gross amount minus tax). Use switch to determine the property code. Property type Residential Commercial Agricultural Commission rate 5% 47% 4% Property code Tax schedule Broker type In-house Accredited Referral Broker Type Tax 20% 25% 10% Your program should also meet the following requirements: a. Allow user to enter uppercase or lowercase letter. b. Round-off results to 2 decimal places. c. Display of outputs should be outside the switch/if structure.

// C++ program to calculate the gross and net commission of a real estate broker

//end of program

Output:
