Representing EOF in C code?

Question

The newline character is represented by \"\\n\" in C code. Is there an equivalent for the end-of-file (EOF) character?

Answer 1

The value of EOF can't be confused with any real character.

If a= getchar(), then we must declare a big enough to hold any value that getchar() returns. We can't use char since a must be big enough to hold EOF in addition to characters.
