Wheel of fortune

Hi
I am writing a wheel of foturne game together with my group. We use an array called

Code:

---

cat

---

to store the categories, but when we have shown fx. the category "Computers" and we move on to the next category which may be "Events", then the array look like this

Eventsrs

How can we delete all content in the array so this bug doesn't appear

An array of what? chars?

If so, then add a 0 in the element after the last charactor, to terminate the string.

It is char, but i tried adding '\0', but it didn't work

Post some code.
