Question $2$

Implement the class Gate class to represent a restricted entrance as depicted in the

UML diagram below:

The function checkPassword$()$ returns true if p is equal to password or false

otherwise.

Write a Graphical User Interface $($GUI$)$ application to simulate an access control pin

pad found at the entrance using the Gate as the model class. The user should be

provided with a description of a gate and a facility to enter a password followed by a #$.$

The application should verify the password and display an appropriate message

$($access granted or denied$)$ to the user.

Given below is the GUI expected from your application:

Note that you are expected to program the GUI manually without using Qt Designer.

Even though the class can be used for multiple gates with different descriptions and

passwords, you only need to test the class with one Gate object.
