operator-() [1/2]

difference_type operator-

right

)

const

Calculates a signed difference between positions of two iterators.

Parameters

right

An iterator whose position is calculated with respect to the position of the current iterator.

Returns

The difference in the positions.

The operator is implemented by delegating the call to the adopted iterator.

The operator is only implemented by random-access transforming iterators, i.e. if the adopted iterator implements the random-access semantics.
