Which is faster post increment or pre increment ? and in which cases should u use either - to incr..

Answer / 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.

Answer / mms zubeir

The above answer seems to be correct but for normal cases
also the behavior is as explained, it is not only for
overloaded case.

A little deeper, since a temporary object is introduced to
swap older and newer values, extra copying is required
which swallow its own CPU time. So the post increment
operator is a bit slower.

But this difference is feeble.
