Formatted vs Unformatted I/O Function in C (Differences) Input output functions in C programming falls into two categories, namely, formatted input output (I/O) functions and unformatted input output (I/O) functions.In this article we will point out major differences between them: in an INPUT statement; with the INPUT, INPUTC, and INPUTN functions; in an INFORMAT statement in a DATA step or a PROC step; in an ATTRIB statement in a DATA step or a PROC step.
