What is the ascii value of EOF in c.?

Question

Any one knows what is the ASCII value of i.

I try printf(\"%d\",EOF);

but its print -1

and also try printf(\"%c\",EOF

Answer 1

EOF (as defined in the C language) is not a character/not an ASCII value. That's why getc returns an int and not an unsigned char - because the character read could have any value in the range of unsigned char, and the return value of getc also needs to be able to represent the non-character value EOF (which is necessarily negative).
