C file size discrepency

Question

I am trying to learn C, and am currently working on a toy script. Right now, it simply opens a text file, reads it char by char, and spits it out onto the command line.

Answer 1

    char tmp = getc(fp); //current letter in file
    int i=0;
    while (tmp != EOF) //End-Of-File (defined in stdio.h)

You need to check the value returned by getc for EOF. Instead, you convert it to a char and then check whether that's equal to EOF converted to a char. But what if the value of char that converts to EOF is actually in the file? Check the docs, getc returns an int.

You have other mistakes as well.
