Impact of void on prototype

hi, what is the difference between these?

Code:

---

int abc() {
...
}

int abc(void) {
...
}

---

what is the impact of void there?

thank you in advance

Try calling both of them with

abc(123);

Oh, and the answer is different in C++, just in case you don't know which language you're programming in.

It's in the FAQ

sorry that i didn't look at it, ty for answers..
