getchar read character getchar( )
provides the simplest means of reading characters from the
standard input for C programs. It returns successive
characters until end-of-file, when it returns
‘‘\0’’. Associated with this routine
is an external variable called fin, which is a
structure containing a buffer such as described under
getc (III). Generally speaking, should be used only
for the simplest applications; is better when there are
multiple input files. getc (III) Null character returned on
EOF or error. 1 should be returned on EOF; null is a
legitimate character.
