C & C++

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?

Rob and Jason are joined by Arnaud Desitter. They first discuss blog posts on parameter passing, fuzzing and push_back vs emplace_back. Then they talk to Arnaud Desitter about his successes improving application performance by reducing memory allocations found using heaptrack.

Rob and Jason are joined by Raymond Chen from Microsoft. They first talk about Herb Sutter’s virtual ISO Plenary Trip Report and some new features voted into the C++23 draft. Then they talk to Raymond Chen from Microsoft about his career working on Windows and the Old New Thing blog.

In our articles, we regularly repeat an important idea: a static analyzer should be used regularly. This helps detect and cheaply fix many errors at the earliest stage. It looks nice in theory. As we know, actions still speak louder than words. Let's look at some recent bugs in new code of the Blender project.

Rob and Jason are joined by Nicole Mazzuca from Microsoft. They first talk about a differential equation library, and modules support in build2 and meson. Then they talk to Nicole from Microsoft’s vcpkg team about some new features in vcpkg to enable teams to host their own libraries.

I am looking for an image processing library for c that can do:

-convolutions

-boundaries detection

-pixel manipulation

Is there such a thing? thanks

Rob and Jason are joined by Carl Cook from Optiver. They first talk discuss an announcement from Khronos that SYCL 2020 has been released, and a blog post from Microsoft on updates to the Visual Studio Code C++ extension. Then they talk to Carl Cook from Optiver about how they use C++ to power everything they do.

The recent Qt 6 release compelled us to recheck the framework with PVS-Studio. In this article, we reviewed various interesting errors we found, for example, those related to processing dates. The errors we discovered prove that developers can greatly benefit from regularly checking their projects with tools like PVS-Studio.

While C++11 is with us for a decade now, it’s good to go back and recall some of its best features. Today I’d like to consider override and final keywords which add a crucial safety when you build class hierarchies with lots of virtual member functions.

Rob and Jason are joined by Sebastian Theophil from think-cell. They first talk discuss a blog post on building a 1 billion LOC project with the Threadripper 3990X and a browser extension for easily searching for C++ reference help. Then they talk to Sebastian about his teams efforts to port their Windows C++ codebase onto MacOS and some of the challenges they dealt with, as well as recent efforts to start porting some of the code into Web Assembly.

Rob and Jason are joined by Victor Ciura. They first talk about different ways to filter a C++ container and a blog post on the Visual C++ blog from the Diablo 4 development team. They then talk to Victor about the Clang Power Tools plugin for Visual Studio which has recently been made free for both open source and commercial use. They also talk about C++ Myths.

There is an open project COVID-19 CovidSim Model, written in C++. There is also a PVS-Studio static code analyzer that detects errors very well. One day they met. Embrace the fragility of mathematical modeling algorithms and why you need to make every effort to enhance the code quality.

Rob and Jason are joined by Klaus Iglberger. They first talk about changes to make the Win32 API more accessible, some C++20 coroutine examples and ISO news. Then they talk to Klaus Iglberger about the SOLID design principles, why they still matter and what C++ developers should know about them.

Rob and Jason are joined by Alessandro Pignotti. They first talk about a linker project, a better assert for constexpr code. Then they talk about Cheerp, LeaningTech’s C++ WebAssembly compiler, how it differs from emscripten, Cheerp optimizations and some of LeaningTech’s other Cheerp products.

One of our readers recommended paying heed to the Espressif IoT Development Framework. He found an error in the project code and asked if the PVS-Studio static analyzer could find it. The analyzer can't detect this specific error so far, but it managed to spot many others. Based on this story and the errors found, we decided to write a classic article about checking an open source project. Enjoy exploring what IoT devices can do to shoot you in the foot.

Rob and Jason are joined by Corentin Jabot. They first talk about a Visual Studio blog post on performance improvements in the ‘inner build loop’, and a ray tracer built into CMake. Then they talk to Corentin about his work in the C++ ISO committee on the Library Evolution Working Group and his thoughts on what could and should make it into C++23.
