Name two properties that a button object can possess?

A button object in a computer should have at least these two properties:
1. It should acknowledge a mouse click or key press.
2. It should trigger a functional code within the software to perform a specific task.

To perform its intended function properly, it is necessary for the button to have a title that clearly describes the function that it performs.

For example, the button could define a new color that is to be assigned to a graphics object or to a font.
Once the button is pressed, the button should trigger execution of code that actually implements the change in color.

These are very for instance for math pemdas parenthesis, exponents, multiplication, division, addition, subtraction without that i would never be able to remember what to do first with it i can remember.
