11 min readTo migrate from Rust to C, you will need to consider the following steps:Understand the differences between Rust and C: Rust is a systems programming language focused on safety, concurrency, and performance, while C is a low-level language with minimal abstractions. Recognize that C lacks Rust's advanced features, including memory safety and ownership annotations. Start by rewriting Rust code in C: Begin the migration process by rewriting your existing Rust code in C.

7 min readIn Sonarqube, regular expressions follow a specific format to define patterns for searching and manipulating text. The format typically consists of the following elements:Delimiters: Regular expressions are enclosed between a pair of delimiters, usually a forward slash ("/"). For example, /pattern/ represents a regular expression pattern. Quantifiers: Quantifiers specify the number of times a character or group of characters can occur in the text.
