I have a template basic class: i would like to send a member function as a parameter to another function, how can i do it? template <class T> class GenericButton { public: GenericButton(const T& t) :m_t(T) {}; auto& getT() { return m_t; } private: T& m_t; }; class Check { private: bool m_generic; void changeType() ..
I have this text from C++ Primer 5th edition: dynamic_cast<type*>(e) dynamic_cast<type&>(e) dynamic_cast<type&&>(e) In all cases, the type of e must be either a class type that is publicly derived from the target type , a public base class of the target type , or the same as the target type . If e has one ..
When trying to create an Android Studio project and setting its location to WSL2 file system, the error is shown: Invalid File Similarly when opening a project stored in WSL2 file system (example, here: wsl$Ubuntuhometyloubuntusomeproject), the error is also related to File name: Gradle could not start your build. > Cannot create service of type ..
Given the following code: for (int i = 0; i < 100; i++) { myFunction(Color(1.f, 1.f, 0.f)); } The constructor of Color would be called 100 times, although it always evaluates to the same thing every time and myFunction does not create a copy (utilizing const Color&). I have already taken the necessary steps to ..

I included all the needed headers (windows.h, winuser.h), but the compiler keeps complaining about "GetDpiForWindow" or "AdjustWindowRectExForDpi" not being defined. Code example: #include <iostream> #include <windows.h> #include <winuser.h> using namespace std; int main() { int dpi = GetDpiForWindow(GetConsoleWindow()); return 0; } Error: error: ‘GetDpiForWindow’ was not declared in this scope; did you mean ‘GetTopWindow’?

The standard library offers std::copy, which can be seen as a generalization/generification of C’s memcpy(). It also maintains the requirement of memcpy(), for the range [first, last) to be disjoint from the range [d_first , d_first + std::distance(first, last)); otherwise we have undefined behavior. My question: Is there a generic version of std::memmove (i.e. which ..
I am solving a problem where, from given list of dates, we have to print the third latest date.

I have a VisualStudio-2019 C++ Project which uses CMake and Ninja to build a dll, the Project uses functions from a few Libraries like protobuf and spdlog, which I have installed using vcpkg. When building, the output gets written to four distinct dll files and all of them are needed for the main-dll to run. ..
