Update main.cpp

Brief Analysis of the C++ Code

1. Function Complexity:

   • The main function is too long and handles multiple responsibilities. It should be refactored into smaller, dedicated functions for clarity.

2. Magic Numbers:

   • Values like 2 for maxConcurrency should be replaced with named constants to enhance readability.

3. Error Handling:

   • There is a lack of error checks after critical operations (e.g., memory allocation and session loading), which could lead to runtime issues.

4. Use of Q_UNUSED:

   • Some instances of Q_UNUSED are unnecessary and could be removed for clarity.

5. Logging Initialization:

   • Logging setup occurs after some log messages are generated, which may result in inconsistent logging behavior.

6. Comment Quality:

   • Comments need improvement for clarity and should better explain the rationale behind certain decisions.

Suggestions for Improvement

• Refactor the main function into smaller, focused functions.
• Replace magic numbers with constants for better understanding.
• Add error handling after critical operations.
• Enhance comments to explain the reasoning behind code choices.
