Top-Down Design
- Top-down design is an approach to modular design where the overall design of a system is developed first, with detailed aspects deferred to later steps.
- It involves breaking down the system's design into manageable parts, focusing on high-level functionalities initially.
- In top-down design, the goal is to ensure that each module provides clearly defined functionality, collectively covering all required functionalities of the system.
Specification of the Calendar Year Program Modules
- Detailed specifications of each module are provided, outlining their functionality, input parameters, and expected output.
- Modules are designed to handle specific tasks, such as retrieving the year from the user, constructing the calendar year, and displaying the calendar.

- Each module's specification is crucial for implementation, ensuring clarity on how it integrates into the complete program.
- Submodules, such as leapYear and dayOfWeekJan1, are utilized within the construct calendar year module to perform specific tasks.

- The modular design provides a roadmap for implementing the complete program, with each module serving a well-defined purpose.
