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
