# Application Review Report

## Entry Point
- The application's entry point is defined in `main.c`.
- Currently, it prints "Hello, World!".

## Code Structure
- The application has a simple structure with a single source file.

## Testing
- Basic test setup to verify that `main()` returns 0.
- The test code attempts to call `main()` directly, leading to a multiple definition error.

## Issues Identified
- The test setup is incorrect because calling `main()` directly causes a multiple definition error.
- Proper testing should involve refactoring the code to separate logic from the entry point.

## Recommendations
- Refactor the application code to isolate logic from `main()` to allow easier testing.
- Expand the code to include more functionalities and corresponding tests.
- Review and improve build process and structure for maintainability.

The review will be updated after fixing these issues.
