(Static allocation that is way too big is frequently detected because of the linker or loader, before the program can even begin execution.)

function that swaps two objects of a class, member for member. We may very well be tempted to utilize std::swap in place of furnishing our individual, but This is able to be extremely hard; std::swap uses the copy-constructor and copy-assignment operator inside of its implementation, and we would finally be attempting to define the assignment operator with regard to alone!
