integer constant zero with C-style typecast to void*, while nullptr is prvalue of type nullptr_t which is integer literal evaluates to zero. For those of you who believe that NULL is same i.e. (void*)0 in C & C++. I would like to clarify that no it's not: NULL - cppreference...

ReSharper C++ warned you about each unused structured binding separately from all the other bindings in the same declaration. We’ve changed this behavior so that if at least one of the structured bindings is used, the inspection does not trigger...
First of all, variable length arrays (VLAs) are not a part of the C++ standard. Declaring a sized array using a variable is against the standard. Arrays should always be initialized with a constant. int arr[n]; // bad int arr[10]; // ok ``` constexpr size_t ARR_SIZE = 100; ...

We’re continuing to track the latest developments in C++ standardization. You can see the latest and upcoming STL features in our Changelog on GitHub, but here are some of the ones I’m most excited about: P0881R7 <stacktrace> P1328R1 constexpr type_info::operator==() P2440R1 ranges:...
In this post I would like to share my observation on where using noexcept really adds value. It is less often than what one might expect, and it does not have that much to do with throwing or not throwing exceptions. The conclusion surprises me a bit, an
