Can you please show me how to code in C++ a calculator? I created the calculator I need the source code to make the buttons work.
You will make a GUI calculator program that will offer the user a button to clear the values, buttons for all digits 0 through 9, as well as the operator buttons for multiplication, division, addition, subtraction, and equal. The user should be able to click the various digit buttons and have them display combined as a single number in a textbox or label control. (e.g., if the user clicks the 2, 4 and 7 buttons successively the textbox or label should display 247)

-Your program should display a form with either a textbox or label control across the top. Below that, the form should display the buttons described in the Assessment description above. (You might want to look and the Windows Calculator or the calculator app on your phone for an example of the layout.)
-Name all of your controls suitable names. Hint: prefixes can make control names easier to distinguish one from the other. Examples include cmd for command button, txt for textbox, and lbl for label. Standard naming conventions are common in the software development field.
-All buttons should be the same size and neatly aligned in a grid pattern below the textbox/label. How you layout the grid is up to you but I would recommend sticking with the standard pattern for calculators. If you would like your operator buttons to be a different size from your digit buttons that is fine but all operator buttons should be the same size and all digit buttons should be the same size. All buttons should display their value on their face and be centered.
-Define any variables you need to keep up with what operator was last clicked as well as the running total. Hint: This can be done with one variable for the total and one variable to indicate the last operator clicked.
-Using events for the buttons, add functionality to each button.
-Digit buttons should append their respective digit to the end of the displayed number.
-Operator buttons should call for currently displayed value to be added or subtracted per the last operator called and then set the operator "flag" variable to indicate what was just clicked. Either the operator button's code or the next digit button clicked will need to clear the display.
-The equal button should call for the last operation to be completed just as the other operators do, then display the final total in the textbox/label control.
-The clear button should clear the textbox/label, (either make it blank or make it display 0), as well as reset all variables as they were when the program began.EXPECTED OUTPUT
A working calculator for multiplication, division, addition, and subtraction.
