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 is not an ASCII character. Its size is not 1 byte as against size of a character and this can be checked by

int main() {
    printf("%lu", sizeof(EOF));
    return 0;
}

However, it is always defined to be -1. Try

int main() {
    printf("%d",EOF);  
    return 0;
}

The key combination for EOF is Crtl+D. The character equivalent of EOF is machine dependent. That can be checked by following:

int main() {
    printf("%c", EOF)
    return 0;
}
