What are the differences between GCC and Clang extensions?

GCC and Clang both support various extensions, but they differ in implementation and features. GCC has a wider range of extensions, while Clang focuses on modern C++ support and better diagnostics.

Can you give examples of specific extensions in both compilers?

Sure! For GCC, there's the __attribute__ syntax for function attributes, while Clang has __has_feature to check for specific features.

Which compiler is better for C++ development?

It depends on your needs. Clang is often preferred for its faster compilation times and better error messages, while GCC is known for its extensive optimizations.

Are there any compatibility issues when using these extensions?

Yes, using compiler-specific extensions can lead to portability issues. Code using GCC extensions may not compile with Clang and vice versa.

What should I consider when choosing between them?

Consider factors like project requirements, desired features, community support, and your team's familiarity with each compiler.
