No, you miss the point. getc() returns a constant called EOF, when it reaches 
the end of file.  This constant is -1.  It is not a character, it is a special 
return value for getc().  This if clause will not filter out any character 
from the input stream, nor will it prematurely declare end of file or 
whatever.
