General Requirements:
- When you click on a button, the number/symbol should appear in the text box.
- When you click on the button “=”, the text box should be replaced by the value calculated.
- If you then click on another symbol, and then another number, the calculator should be able to continue processing.
- When you click CLEAR, the text box should empty, and all previously calculated numbers be forgotten.
- Error messages should appear when a user does something illegal, like divides by zero, or clicks: “1” “+” “=”. The error message should clear the calculator, and let the user start over.
- The calculator must do correct math, and needs to handle decimal points and negative values.
- The calculator does NOT need to function from values typed into the text box.
Design Requirements:
- The math functions should be implemented using Delegates, so that the program may be easily modified in the future to handle other functions.
- Use event handlers for error messages.
