Summary
As this chapter has demonstrated, writing standard C++ ensures code portability, compatibility, and maintainability across different platforms and compilers. We learned that by adhering to the ISO/IEC C++ standard, we can create code that behaves predictably and is less prone to bugs and platform-specific issues. Standard-compliant C++ code also benefits from generic compiler optimizations and future language enhancements, while ensuring long-term relevance and performance, as we learned in this chapter.
On the other hand, using C++ compiler-specific extensions can provide performance optimizations specific to a platform and compiler, access to advanced features that are not yet standardized, and integration with vendor-specific tools. However, the extension may introduce portability issues, dependencies on specific compiler versions, as well as divergence from standard C++ practices, which can impact code maintenance and interoperability across different platforms and compilers...
