C & C++

I am writing a unit test and mocking library in C and I want to set the call stack memory to some pre determined value like memset. I want to do this before the test function is called so the test writer can verify they aren't using uninitialized memory in their tests. Is there any somewhat portable way to do this?

Is there a library for C, providing thread safe (high performance), and structured logging? An example for rust is the Tracing crate for rust (from Tokio). It should support several outputs as well.

The latest major version of the GNU Compiler Collection (GCC), 13.1, was released in April 2023. Like every major GCC release, this version brings many additions, improvements, bug fixes, and new features. GCC 13 is already the system compiler in Fedora 38. Red Hat Enterprise Linux (RHEL) users will get GCC 13 in the Red Hat GCC Toolset (RHEL 8 and RHEL 9). It's also possible to try GCC 13 on godbolt.org and similar web pages.

Like the article I wrote about GCC 10 and GCC 12, this article describes only new features implemented in the C++ front end; it does not discuss developments in the C++ language itself. Interesting changes in the standard C++ library that comes with GCC 13 are described in a separate blog post: New C features in GCC 13

Overview of the CMake controversy, and break down the pros and cons of the critical C++ tool.

What's the hate for CMake all about? Is CMake really that bad?

Because the world isn't weird enough?

I don't know I feel like there aren't many resources to learn C++. Maybe it is because I am not looking hard enough. Can someone here recommend some websites or videos?

I haven't really understood the difference between

i++ and ++i

I am learning C++ and in my book using namespace std is written in every program. I understand that std::cout <<"hello"; can be simply written as cout << "hello"; by using namespace std.

Why?
