C++20 has way more to offer than the big four concepts, ranges, modules, and coroutines.
Here are a few of the shining pearls.

The spaceship operation automatically creates the six comparison…

Have you ever written code like this:
void f(bool b, long x, long& s) { if (b) s += x; }
Probably you have. Would you like me to tell you how much performance you left on the table? With a small…

Imagine writing parallel code that can run on any platform - CPUs, GPUs, DPUs, specialized accelerators, etc. It's no longer just a dream - you can do it in Standard C++!

Parallelism is increasingly…

An essential aspect in designing C and C++ systems is to validate the execution flow and resource contention of a proposed approach in the contexts of symmetry and orthogonality.

The role of symmetry…
