## Challenging aspects
### Challenging aspects in above code
The provided code snippet contains several nuanced challenges that require careful consideration:
1. **Handling Multiline Comments**: The code needs to correctly identify multiline comments that start with `/*` and end with `*/`. The logic must ensure that any text between these markers is properly skipped without accidentally processing it as code.
2. **Inline Comments**: Inline comments starting with `//` should be identified correctly even when they appear at different positions within a line (not just at the end).
3. **Preservation of Code Integrity**: The code must preserve valid code segments while removing only comment sections accurately.
4. **Edge Cases**: Handling edge cases such as comments within strings or comments that contain sequences resembling comment delimiters but are not actually comments.
5. **Performance Considerations**: Efficiently processing potentially large bodies without unnecessary overhead.
6. **Error Handling**: Providing meaningful warnings when encountering unexpected situations such as comments not at the end of lines or unclosed multiline comments.
### Extension
The above logic can be extended by introducing additional requirements:
1. **Nested Multiline Comments**: Handle nested multiline comments correctly.
2. **String Literals**: Ensure that comment delimiters inside string literals are not mistaken for actual comment markers.
3. **Preprocessor Directives**: Extend handling to include preprocessor directives (e.g., `#define`, `#include`) which might have inline comments.
4. **Different Comment Styles**: Support different styles/formats used across various programming languages (e.g., HTML-style comments ``).
5. **Multithreading Considerations**: While not generic multithreading safety per se, consider processing multiple files simultaneously where each file may have its own comment handling rules.
## Exercise
### Problem Statement
You are required to extend the provided [SNIPPET] so that it can handle additional complexities while processing constants' bodies within given source code files:
1. **Nested Multiline Comments**: Ensure that nested multiline comments are handled correctly.
2. **String Literals**: Ensure that comment markers within string literals (e.g., `"/* not a comment */"`) are ignored.
3. **Preprocessor Directives**: Process preprocessor directives (like `#define`, `#include`) which may contain inline comments.
4. **Support Different Comment Styles**: Add support for HTML-style comments (``).
You should also provide meaningful warnings for any inline comments not found at the end of lines or unclosed multiline comments.
### Requirements
- Your solution should be efficient even for large input files.
- Maintain readability while handling nested structures.
- Provide meaningful warnings when encountering unexpected comment formats or unclosed multiline comments.
- Ensure your solution is robust against edge cases such as strings containing comment-like sequences.
