C++ Riddle

[:-\]

If you want one in Java, I'll be glad to edit my normal palindrome tester which I did for an AP Java class, now it tests entire sentences, here's the source below:

import cs1.Keyboard;
import java.util.Random;
import java.util.StringTokenizer;
import java.text.NumberFormat;

public class PalindromeTester
{
    public static void main (String[] args)
    {
		String str, another = "y", lower;
		int left, right;
		
		while (another.equalsIgnoreCase("y"))
		{
			System.out.println ("Enter a potential palindrome:");
			str = Keyboard.readString();
			
			lower = str.toLowerCase();
			
			left = 0;
			right = str.length() - 1;
			
			while (lower.charAt(left) == ' ' || lower.charAt(left) == '.' || lower.charAt(left) == ',' || lower.charAt(left) == '?')
					{left++;}
			while (lower.charAt(right) == ' ' || lower.charAt(right) == '.' || lower.charAt(right) == ',' || lower.charAt(right) == '?')
					{right--;}
			
			
			while (lower.charAt(left) == lower.charAt(right) && left <= right)
			{
				
				left++;
				right--;
			
				while (lower.charAt(left) == ' ' || lower.charAt(left) == '.' || lower.charAt(left) == ',' || lower.charAt(left) == '?')
					{left++;}
				while (lower.charAt(right) == ' ' || lower.charAt(right) == '.' || lower.charAt(right) == ',' || lower.charAt(right) == '?')
					{right--;}
								
			}
			
			System.out.println();
			
			if (left < right)
				System.out.println("That string is NOT a palindrome.");
			else 
				System.out.println("That string IS a palindrome.");
			
			System.out.println();
			System.out.print("Test another palindrome (y/n)? ");
			another = Keyboard.readString();
			}
    }
}

I know I have a lot of useless classes being imported, but since I use an outline for every program thats been premade, I really don't delete any...

If it has to be in C++, drop me a line, I still remember of some of that stuff...
