Our class was challenged by a professor at uni that if we were able to find a algorithm that fittingly describes the following Big-O-Notation, we'd instantly pass his class. I wanted to ask if any of you know how this could be done since I've been...
I'm designing and programming an elevator-like robot for a high school project. Could I possibly do anything to make this any simpler? Or better? I have attached a picture of my design that I made in AutoCAD Inventor with labels.
I have to dynamically create push buttons depending on user inputs, therefore if the user gives a large input number, the widget containing the push buttons has to have the ability to scroll up and down.
I am trying to attach a servo on an Arduino (branded) Robot but not sure whhich pin to use for the bellow code. Most people seem to recommend to use pin 9 and 10 to control the servo for arduino Unos. However, I can't use Pin 9 because that is...
Everything works perfectly fine but the thing is that everytime a user creates an account, it replaces the old credentials stored in the already existing file. I want to be able to store multiple user credentials so that multiple users can login....
Processing large amounts of data (gigabytes) I use indexes to data arrays. Since access to data could lead to cache inefficiency, I want to cache some data from array together with the index which gives dramatic speedup for operations through...
at the moment I am using a windows machine and wanted to try out windows subsystem for linux(wsl) for c++ development. Visual studio code(vsc) provides a neat extension for working on the subsystem that works quite well. One thing I could not get to...
With the attribute [ ] used for plain old data (POD) arrays like ‘std::size_t[]’ the template specialization for zero structure size could be as small as index member is has, not occupying memory for the data array.
I make an executable file using cmake, and it runs perfectly on my computer, but when I share it to another computer and I open it, it says libcrypto-x64.dll was missing. I tried to find it on web and searched everything but I didn't find anything....
I wrote the following code that has two lambdas. One of them explicitly captures i while the other doesn't. Note i is constexpr so we don't need to capture it explicitly.
My question is why func(lambda2) doesn't compile while func(lambda) does?...
I'm working on a native Windows app to stream part of my desktop to a microcontroller as part of a creative tech project. It's written using C++ and is curently a console app. I have no intention of switching to Javascript, C# or anything else....

PIMPL stands for P ointer to IMPL ementation. The implementation stands for implementation detail : something that the users of the class need not to be concerned with.
Qt's own class implementations cleanly separate out the interfaces from the...
I have suprising observation that steady_clock gives poor 10ms resolution when measuring durations. I compile for windows under cygwin. Is it sad true or am I doing sth wrong?
auto start = std::chrono::steady_clock::now(); /*...*/ auto end =...
Question:
I've been exploring different types of casting in C++, particularly const_cast, which is used to cast a const T to T, where T represents a data type. However, I encountered a perplexing behavior when experimenting with const_cast....
I am currently working on adding CMake support to a library that currently uses waf as its build system. The code I have for CMake is excruciatingly slow compared to the existing build system with waf, and I believe it is because of the following...
