C++ High Performance

Non-performance-related C++ language features

In some discussions about C++ versus other languages, it's concluded that C++ should only be used if performance is a major concern. Otherwise, it's said to just increase the complexity of the code base due to manual memory handling, which may result in memory leaks and hard-to-track bugs.

This may have been true several C++ versions ago, but a modern C++ programmer relies on the provided containers and smart pointer types, which are part of the STL.

We would here like to highlight two powerful features of C++ related to robustness rather than performance, that we think are easily overlooked: value semantics and const correctness.
