 Input and output facilities are provided by the standard library <stdio.h> and not by the language itself. |
| A text stream consists of a series of lines ending with ‘\n’. The standard library takes care of conversion from ‘\r\n’ ’\n’ |
| A binary stream consists of a series of raw bytes. |
| The streams provided by standard library are buffered. |
