Hi everyone, here is a list of websites that I use for C++:

• https://godbolt.org/: compiler explorer, allows you to quickly test code and see the disassembly, integrates many libraries and tools (PVS, clang-tidy, …). It can even do CMake projects with multiple files!
• https://en.cppreference.com/w/Main_Page: The C++ reference.
• https://cppinsights.io/: see what the compiler does for you behind the scene.
• https://quick-bench.com/: make quick comparison/benchmark

What are you all using? Post your comments :)
