Create a very simple four function integer calculator with buttons for Add, Subtract, Multiply, and Divide,
and with two text-type input fields. When the user enters two numbers and clicks one of the buttons, the answer is displayed where shown.
Your program must use an alert to tell the user about any errors.
The possible errors include:
One or both input fields are blank
One or both input fields < -9999 or greater than 9999
Divide by zero
Illegal character in either input field.
Only 0, 1 ,2 ,3 ,4 ,5 ,6 ,7 ,8 ,9, and – are allowed.
The program should also include instructions to the user.
A set of instructions for installing the application supported with screenshots is also required.
