Therefore, in the declaration −. Iterators generalize pointers to elements of an array (which indeed can be used as iterators), and their syntax is designed to resemble that of C pointer arithmetic, where the * and -> operators are used to reference the element to which the iterator points and pointer arithmetic operators like ++ are used to modify iterators in the traversal . c iterate through double pointersalons to rent in leeds. sizeof() returns the size of a variable.
