(Simple Calculator Application) In this exercise, you will add functionality to a simple calculator application. The calculator will allow a user to enter two numbers in the Text- Boxes. There will be four Buttons—labelled +, -, / and *. When the user clicks the Button labelled as addition, subtraction, multiplication or division, the application will perform that operation on the numbers in the TextBoxes and display the result. The calculator also should clear the calculation result when the user enters new input. displays the com- pleted calculator.
a) Copying the template to your working directory.
b) Opening the application’s template file.
c) Coding the addition Click event handler.
d) Coding the subtraction Click event handler.
e) Coding the multiplication Click event handler.
f) Coding the division Click event handler.
g) Clearing the result.
h) Running the application.
i) Closing the application.
a) Copy the directory C:\Examples\
Tutorial06\Exercises\SimpleCalculator to your C:\SimplyCSP directory.
b) Double click SimpleCalculator.sln in
the SimpleCalculator directory to open the application.
c) This event handler should add the two numbers and display the result.
d) This event handler should subtract the
second number from the first number and display the result.
e) This event handler should multiply the two numbers and display the result.
f) Write event handlers for the TextBoxes’ TextChanged events.
Write code to clear the result Label (lblResult) after the user enters new input into
either TextBox.
h)Select Debug > Start to run your application. Enter a first
number and a second number, then verify that each of the Buttons works by clicking each, and viewing the output. Repeat this process with two new values and again ver-ify that the proper output is displayed based on which Button is clicked.
i) Close your running application by clicking its close box.
