palindrome

Don't expect anyone to do your homework assignment for you.

Here is one way to do it:  First get the length of the string and save each character to an array.  Reverse the array and copy the characters to a new string variable.  Then compare the original string to the reverse string (keeping all the characters either upper or lowercase).  If it matches, then it's a palindrome.

Another way:  Use a For loop stepping backwards from the length of the string.  Extract each letter using the value of the control variable and concatenate it to a new string.
