How is the constructor any different from the function?

Not sure how to do that or what to look for. It appears to me without knowing how the compiler works that there would be some allocating and copying of memory which is more overhead than assigning a value directly. Maybe it’s totally trivial but if it is it’s something I should cut out of my design going forward.
