Comparing strings

Does anyone know how to compare string[i] with a letter, say "x" in a for loop? I've tried to do this:

Code:

---

if (string[i] == "x"){}

---

But my compiler says: ISO C++ forbids comparison between pointer and integer. i is defined as int i = 0 and string is a C++ style string. Any help would be nice.

Single characters go between single quotes.

Code:

---

if (string[i] == 'x') {}

---

Of course! Thank you some much, such a simple mistake!
