Increments or decrements the iterator.

Let current_, end_, stride_, and missing_ be the data members of the iterator.

1) Equivalent to

missing_ = ranges::advance(current_, stride_, end_);
return *this

Before the call current_ should not be equal to end_.

2) Equivalent to ++*this;.

3) Equivalent to auto tmp = *this; ++*this; return tmp;.

4) Equivalent to

ranges::advance(current_, missing_ - stride_);
missing_ = 0;
return *this;

5) Equivalent to auto tmp = *this; --*this; return tmp;.

6) Equivalent to

if (n > 0)
{
    ranges::advance(current_, stride_ * (n - 1));
    missing_ = ranges::advance(current_, stride_, end_);
}
else if (n < 0)
{
    ranges::advance(current_, stride_ * n + missing_);
    missing_ = 0;
}
 
return *this;

If n > 0, then before the call to this function the ranges::distance(current_, end_) must be greater than stride_ * (n - 1).

Note that if n < 0, the ranges::distance(current_, end_) is always greater than (non-positive) stride_ * (n - 1).

7) Equivalent to return *this += -n;

Parameters

n

-

position relative to current location

Return value

1,4,6,7) *this

2) (none)

3,5) a copy of *this that was made before the change
