My loop duplicates the last char... (Language C)(feof)(char by char)

Question

Yo guys,

I'm trying to read a text file:

while(!feof(fp)){ 

    fscanf(fp, "%c", &c);

    printf("%c", c);

}

But... the output always duplicate the last char, I dont know why... :/

Any idea?

Are you saying that the output of your program is the first character of the input file `fp` repeated? Is it [the first char] repeated once for every character in the input file? Is this really the entirety of your loop and I/O? What does your input file look like? Is `c` an `int` or an `unsigned char`? — Matthew Hall, Nov 22 '12 at 23:46
c is a char... I'm reading a text file that looks like it "+1 2", but the number 2 appear duplicated when I use that code, dont know why. Anyway, the last char is always duplicated... — Frank, Nov 22 '12 at 23:54
possible duplicate of ["while( !feof( file ) )" is always wrong](http://stackoverflow.com/questions/5431941/while-feof-file-is-always-wrong) — Thomas Padron-McCarthy, Mar 30 '13 at 07:56
