Calculator Write a program that allows the user to specify two numbers and then adds, subtracts, multiplies, or divides them when the user clicks on the appropriate button. The output should give the type of arithmetic performed and the result. See Fig. 4.26. Note: Whenever one of the numbers in an input text box is changed, the output text box should be cleared. Also, if the number 0 is entered into the second text box, the division button should be disabled.
