Using C++,

Add a function to both the Sale and Salesperson classes that returns the private salesperson ID number. Write a main()function that contains an array of five Salesperson objects and store appropriate data in it. Then, continue to prompt the user for Sale data until the user enters an appropriate sentinel value. For each Sale transaction entered, determine whether the salesperson's ID number is valid. Either display an error message, or use the friend display()function to display all the data.
