As Dave said, printf() is better solution.

   printf("\nCopying...\n");

    while (!feof(inFp)) {
        inChar = getc(inFp);
        printf("\nThe %i item of file1 : <%02X>\n",i, inChar);

        putc(inChar, outFp);
        printf("The %i item of file2 : <%02X>\n",i, inChar);*/
        i++;
    }

But the problem exists. If you trace the chars with this source code, by making file1 empty, you will see, by copying to file2, that there is an <FFFF> Try it!
