Summary
With this chapter, we hope you have grasped the critical importance of following the specified order of everything C++-related to ensure predictable and error-free code execution. You should also understand the importance of not having a specified order of execution.
With this in mind, we encourage you to go and experiment with the online playground offered by Compiler Explorer. It offers a large collection of compilers. Just bear in mind that if two compilers have generated different results for the code you wrote, then maybe you have ventured into unspecified/undefined behavior territory.
The next chapter explores the challenges of memory management in C++.
