So far, we've been calling printf to print formatted output to the ``standard output'' (wherever that is). We've also been calling getchar to read single characters from the ``standard input,'' and putchar to write single characters to the standard output. ``Standard input'' and ``standard output'' are two predefined I/O streams which are implicitly available to us. In this chapter we'll learn how to take control of input and output by opening our own streams, perhaps connected to data files, which we can read from and write to.
