It isn't a whole lot of help to 1) give away an answer 2) give an answer she cannot use.
Kristina, please stop spamming the forum. You are actually less likely to get help when you do that than with a single, well-thought post.
To test whether or not you have a palindrome, you will need to consider the indices into the array of characters that make the string. For example:
0 1 2 3 4 5 6 7 : index
K R I S T I N A : letter
To check for a palindrome requires a little (teeny tiny) bit of math. "KRISTINA" has eight letters, so the indices are zero to seven.
Use a loop and two counters. One counter goes from zero to seven. One counter goes from seven downto zero. Inside the loop just check to see if the letter at the first index matches the letter at the second index. If it doesn't, then the string is not a palindrome.
Extra credit hint: You don't actually have to stop looping when the counters hit seven and zero (respectively). (You can stop sooner.)
