Thread: faqs question

hi all
i am about to finish allot of thing that was getting in my way , any way
i am reading the FAQ now and i while i am reading i get confused about feof faq

The function tests the end-of-file indicator, not the stream itself

does this mean it reads from the stream (FILE *) then it checks the buffer
i mean like that

-------file-------
a
a
a
--------file--------

Code:

while(!feof(file))
    {
        fgets(buffer,sizeof(buffer),fp);
        printf("%s\n",buffer);
     }

it will read and print "a a a " then it will read the EOF it self and print it or what ?
sorry it might be a really dump question but i couldn't get it
thanks

feof() returns 0 if EOF is not reached

so !feof() , return 1 and loop will run until EOF is reached

EOF will not get printed

sorry but you didn't add any thing new
i am asking why i has printed " garbage " and didn't return any thing but 0 when the file EOF has reached does it read the test ?

and there is another things
first
char buf[BUFSIZ] = "Garbage";
is BUFSIZ is a macro defined in stdio ?

actually i am wondering how did it work in FAQ's source with out #define it ?

feof() is a state (in response to past events), not a prediction (of future events).

so that's why

and the call to feof() returns FALSE, and we start to go through the loop again

right ?

Yes, which evetually ending up with printing the grabage value.



Shouldn't this be

Code:

while(!feof(fp))
