C: is a number even!!

how can i check if a number is even in C...is there a function to do so, if so which header file is it in?


Thanks,
Steve

if(num%2==0)
//then the number's even :)

thanks

just use macros like

Code:

---

#define iseven(c) (c%2==0)

---

usage

Code:

---

int a;
........
if (iseven(a) ) ..........;

---

(num & 0x1) would be faster, accomplishing the same.

Now that's a smart one... have to keep that one in mind!
