Thread: Palindrome Coding trouble

I am trying to code a Palindrome program...I keep on getting a runtime error called

Index out of range: 3 string: mom

yeah I can't figure out why though...here's my code

Code:

void Palindrome()
{
	apstring Input;
	apvector<char> Word;
	apvector<char> ReversedWord;
	int Length = 0;
	int c = 0;
	int d = 0;
	bool Palindrome = true;

	cout << endl;
	cout << "Enter in a word to see if it is a palindrome: ";
	cin >> Input;

	ToLower(Input);
	Length = Input.length();
	
	Word.resize(Length);
	ReversedWord.resize(Length);

	for(int b = Length; b > 0 ; b--)
	{
		Word[d] = Input[b];
		d++;
	}

	for(int i = Length; i > 0; i--)
	{
		ReversedWord[c] = Word[i];
		c++;
	}

	for (int e = 0; e < Length; e++)
	{
		if(ReversedWord[e] == Word[e])
		{Palindrome = true;}
		else
		{Palindrome = false;}
	}
	
	if (Palindrome == true)
	{cout << "This word is a palindrome." << endl;}
	else
	{cout << "This word is not a palindrome." << endl;}

}

yeah this is it by the way my headers are

<iostream.h>
<strutils.h>
<apstring.h>
"apvector.h"


yeah thanks for your help
