Question

what is cascading of input &output operators? give examples

Answer 1

The multiple use of input or output operators (“>>”or”<<”) in one statement is called cascading of I/O operator. The statement using multiple output operators (“>>”) is said to be cascading output operator and the statement involving multiple use of input operators (“<<”) is said to be cascading input operator.
