Category: Demystifying C++

In our latest article on “Demystifying C++”, we dive into the crucial differences and best practices for handling return values in C and C++ functions. Understand why a missing return value can lead to undefined behavior and how compilers like clang and GCC use `__builtin_unreachable` to help uncover potential stability issues.

We uncover how the standards in C and C++ differ and why this is critical for your programming. Plus, we reveal how compiler optimizations can have unexpected effects when return values are missing.

Read our full article to learn how to take such warnings seriously and control your code behavior with options like `-Werror=return-type` or `–no-strict-return`.
