Write a program that allows furniture sales (item and price) to be displayed in a list-box one at a time, and then shows the total commission of the sales (5%) upon request. The user should type each item and price into the text boxes and then click on the Display button. This process can be repeated as many times as desired. At any time, the user should be able to press the Show button to display the total commission of all the sales that were entered. Additionally, as soon as the user clicks on the Display button (to display an item and price just entered) the text boxes for Item and Price should be cleared. For this program, you can assume that the user will enter all the sales and then compute the total commission.

Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations: a. double the number. b. reverse the digits of the number. c. raise the number to the power of 2, 3, or 4. d. sum the digits of the number. e. if the number is a two-digit number, then raise the first digit to the power of the second digit. f. if the number is a three-digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit. after performing an operation if the number is less than 10, add 10 to the number. also, after each operation determine if the number is prime. each successive operation should be performed on the number generated by the last operation. your program should not contain any global variables and each of these operations must be implemented by a separate function. also, your program should be menu driven. 7.
