Point out the error, if any, in the following program. #include "stdio.h" main() { unsigned char; FILE *fp; fp = fopen ("trail", "r"); while (( ch = getc (fp)) ! = EOF) printf ("%c", ch); fclose (fp); }

Correct Answer: EOF has been defined as #define EOF -1 n the file "stdioh" and an unsigned char ranges from 0 to 255 hence when EOF is read from the file it cannot be accommodated in ch Solution is to declare ch as an int
