Exploring static analysis with Clang-Tidy

As we delve deeper into the realm of static analysis, a tool that stands out for its versatility and depth is Clang-Tidy. Developed by the LLVM Foundation, the same organization behind the Clang compiler, Clang-Tidy is a linter and static analysis tool designed for C++ code. It extends beyond the capabilities of what a traditional compiler would check, offering a range of diagnostics that include stylistic errors, programming mistakes, and even subtle bugs that are often missed during regular code reviews. Previously, we explored how Clang-Tidy can be adept at code formatting; now, we will explore its prowess in static analysis, uncovering its ability to scrutinize C++ code at a level that ensures not just conformity but also excellence in coding standards.

Clang-Tidy works by using the Clang frontend to parse C++ code, enabling it to understand the code’s structure and syntax in depth. This deep understanding allows Clang-Tidy to...
