In modern C++ is it possible to write a member function alias with a syntax different from this: class C { int f(int a) { return ++a; } int g(int a) { return f(a); } }; I tried in a few ways, none of which work: class C { int […]

I have encountered an unexpected for me problem of connecting plugins to C++ project in Unreal Engine 5.4.4. I am not experienced in Unreal Engine, so the problem may be trivial but I hope for your understanding. In general I am trying to connect IK Rig module in Build.cs of […]

I am experimenting with writing a lightweight signals/observer class that has the following interface (implementation removed for simplification): template class Signal { public: void connect(AbstractSlot& slot); void disconnect(AbstractSlot& slot); void emit(const ARGS&...args); //... }; Which is used, for example, like so: Signal signal1; //A signal with no parameters Signal signal2; […]

I'm trying to understand tensorflow at a hello world level I'm getting larger values than I should for my bounding boxes points the way I understand it is that when you normalize you get a value from 0 to 1 then you multiply that by image height or width then […]

For readability purposes I'm using the alternative not token whenever I intend to use the unary ! operator. E.g. if (not SomeFunction()) instead of if (!SomeFunction()) Is this good/current practice? Is there anything wrong with doing this systematically? I know this is mostly opinion based, sorry.

take the following classes for example: class Test { public: int a=1;// no error }; class Test { public: int a; a=1; // error }; Here the second case gives error. After a few searches the reason i found is that because class only allows declaration and no assignment as […]

If i have a constexpr function with a constexpr local variable its value must be known at compile time constexpr int addSquare(int x) { constexpr int multiplier = 2; return x * x + multiplier; } int main() { static constexpr int result = addSquare(3); return result; } I believe […]

I'd like to write some MSVC plugin/extension. I've installed the Visual Studio SDK and followed this simple "tutorial". Now i have simple, working extension which i can add to any of my other VS projects. The only problem is that there is no C++ template in the VS templates to […]
