Quick question, should be simple to answer.

Hello. I recently started taking a class on C programming, and am stuck. One part of the program needs to tell the user if the number they entered is odd or even. How would I go about doing this? I was told to look at the remainder, but am still confused on how to make this work. Any help would be greatly appreciated. Thanks.

An odd number will have a remainder when divided by 2 an even number won't. To get the remainder use the % operator.

Code:

---

if (Number %2)

---

That is all I need to do? I've been trying many different things, such as

Code:

---

if ((number % 2) == (number / 2))

---

I did not realize that it was so simple. Thanks a lot for your help!

Code:

---

if (number & 1) { /* number is odd */ }

---

Assuming that number is an integer type, this works. I'll leave it as an exercise for you to figure out why.
