11.4 FORMATTED INPUT
An operator at the console is unlikely to enter data which appears formatted. In general, formatted input will come from a file. We will be discussing files in Chapter 14 “File Handling”. It is perceived that reading from file or reading from console is more or less identical.
The term Formatted Input reminds us of the story of a great scientist Newton. He dug a big and a small hole for his cat and kitten. He was forgetful of the fact that kitten can enter through the bigger hole meant for the cat. It is comfortable to have a system which can read format-free input as well as formatted input. In general, the statement
cin >> x >> y ;
will read x and y whether input is formatted or unformatted. See Program 11.4.
