Danielle, Edward, and Francis are three salespeople at Holiday Homes. Write an application named HomeSales that prompts the user for a salesperson initial (D, E, or F) input as a string. Either uppercase or lowercase initials are valid. While the user does not type Z, continue by prompting for the amount of a sale. Issue the error message "Sorry - invalid salesperson" for any invalid initials entered. Keep a running total of the amounts sold by each salesperson. After the user types Z or z for an initial, display each salesperson’s total, a grand total for all sales, and the name of the salesperson with the highest total unless there is a tie. If there is a tie, indicate this in the program's output with the message: "There was a tie".
An example of the program is shown below:
Enter a salesperson initial >> D Enter amount of sale >> 10 Enter next salesperson intital or Z to quit >> d Enter amount of sale >> 2 Enter next salesperson intital or Z to quit…

This function should be called by main once for each of the five scores to be entered. ⚫ void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. ⚫int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100.
