Answer Posted / me
In normal cases where we use x++ or ++x for integer
variables in loops etc, both behave the same.
However, when we have classes that overload the ++
operator, it's faster to use the ++x rather than x++.
This is because when we do x++, a temporary object is
created to point to the original value, then the value is
incremented, and the pointer is updated and returned.
in case of ++x, just the value is incremented and pointer
to itself is returned. therefore ++x is faster in this case.
