what does decltype do in c++? give me various ways to use it In C++, decltype is a keyword introduced in C++11 that inspects the declared type of an expression. The result is the type itself, which can be used in various contexts, such as for declaring variables, function return types, template argument deduction, and more. for now alive at sk-experiments/cpp/experiments/curiously_recurring_template_pattern/main.cpp at… The collection of Srecko Kostic's experiments.

Convert the hook to a component and wrap the child in it. This article solves a problem with an example of how to use a hook such as useState in a class component. It works for other hooks as well. Run the code here: https://codepen.io/Flexos96/pen/bGOzOxr?editors=1010 Read the code here: …

Answer what happened what went right what went wrong what can i learn from it one thing i’ll do different * what happened I started to solve: 2477. Minimum Fuel Cost to Report to the Capital It is a medium question with a dynamic programming tag and bonus points because it is a…

i first sketched out the results of preorder traversal to see expected outputs which should help me understand all the cases that i need to handle in my implementation then i realized that since a tree is recursive data structure, at each node i have only information…

Detailed explanation of how to rotate vector around another vector using information that rotation around the origin 0,0 is the simpler form of rotation. If we rotate vector A around vector B, then vector B is our origin, but we don’t want that, we want origin to be 0,0. Therefore we remove offset which is vector B, so we can rotate vector A freely because now our center of rotation is origin 0,0. All we have to do now is add back to the result the offset we initially removed.

I have studied programming for some time and thought I knew quite a few things and programming practices. However, whenever I read a new book, I find something new. Sometimes that news is mind-blowing, especially when reading the content created by people like Bjarne Stroustrup. For example, I was reading…
