Question

Develop an object-oriented programming (OOP) application to create two clocks that display simultaneously and allow for user input using secure and efficient C++ code.

Create a Clock12 class to display time in the 12-hour format, not exceeding 12:59:59.
Create a Clock24 class to display time in the 24-hour format, not exceeding 23:59:59.
Both clocks should display on the screen with the current time in the proper format.
Which of the following options is a correct step to start the implementation?
a. Define a class for Clock12 with appropriate time validation.
b. Implement user input functionality first.
c. Start with Clock24 class and later modify it for Clock12.
d. Skip user input and focus on displaying the current time.

Answer 1

The correct step to start implementing an OOP application for two clocks is to define a class for Clock12 with appropriate time validation before adding user input or moving on to the 24-hour clock.

Step-by-step explanation:

To start the implementation of an object-oriented programming (OOP) application that enables the simultaneous display of two clocks with user input, the first step would be to define a class for Clock12 with appropriate time validation. By focusing on this class, you can ensure that it encapsulates all the necessary functionality for a 12-hour format clock before moving on to the 24-hour format with the Clock24 class. Only after both classes are properly defined and tested for their core functionality, should user input functionality be added to interact with the clocks.
