Disk Input Output:
There are two of Disk Input Output:
> High Level / Std Disk Input Output Disk.
> Low level Input / Output Disk.

In High Level / Std Disk Input Output Disk there are two sub types viz. Text and Binary.
> In Text there are two types Formatted and Unformatted.  The formatted data types are char, int,   float, string where we can use fprintf() and fscanf() respectively. 
 While the Unformatted data types are char, int, float, string where char reads/writes char by char   using getc(0, fgetc(), ptc(), fputc(). The int and float data types have no Std. library function.

> fs = fopen ( s, "r") - Return NULL if file is absent and Returns address of structures, if present.
>ft = fopen ( t, "w") - Creates new file if file is absent.
