Every IDE I've used would show you the name of parameters when you hover the function. These days there are even inlay hints that will transform countDominoTiling(4, 7) to countDominoTiling(width: 4, height: 7). Another option would also be to just pass a struct: struct dimensions dim = { .width = 4, .height = 7}; countDominoTiling(dim); My C++ is rusty so this might not compile but you get the idea. There isn't a big difference with just one simple thing, but when you're having 10 of these things, with some classes having classes in themselves, it quickly becomes a mess.
