Challenge – 4

Problem Statement:

Develop a Business Management System capable of handling assignments and projects for three clients, namely Neeraj, Abhishek, and Rahul. The system should provide functionalities to log assignments/projects and retrieve them based on client input.

Key Requirements:

1. Logging Functionality:

• The system should allow users to log assignments or projects for each client.
  • Users should be prompted to select the client (Neeraj, Abhishek, or Rahul) and specify whether it’s an assignment or a project.
  • Upon selection, users should input the details of the assignment or project, which should be timestamped and stored in corresponding files.

• Retrieval Functionality:

• Users should have the ability to retrieve assignments or projects for a specific client.
  • The system should prompt users to select the client and specify whether they want to retrieve assignments or projects.
  • Upon selection, the system should display the stored assignments or projects for the chosen client.

• User Interaction:

• The system should provide a user-friendly interface, guiding users through the logging and retrieval processes.
  • Users should be informed of successful logging or retrieval operations.

• Error Handling:

• The system should handle invalid inputs gracefully, prompting users to enter valid inputs when necessary.
  • Errors such as selecting an invalid client or input option should be handled appropriately with clear error messages.

Assumptions:

• Each client has separate files for storing assignments and projects.
• Timestamps are appended to each entry to maintain a record of when the assignments/projects were logged.
• The system operates in a command-line interface without graphical user interface (GUI) elements.
• Input/output operations are conducted through standard input (console) and output (console).
