HELP W/ Palindrome function!!??

I know that you guys are all probably Palindromed out but I wrote a program and it's telling me that m is an undeclared identifier and also a unreferenced local varibale errors....any idea on how to fix it??

Code:

#include <iostream>
#include <string>
using namespace std;
//PROTOTYPE

string Reverse(string s, int m);   //reverse s from
bool IsPalindrome(string s); // Checks if it is Palindrome
               
// MAIN PROGRAM
int main ()  {
string word;
string s;
int m;
	
cout << " What word would you like to test to see if it is a Palindrome?"<< endl;
      cin >> word;

string Reverse(); 
bool IsPalindrome();
	
	
	return 0;

}
//IMPLEMENTATION OF PROTOTYPE
string Reverse(string s, int m) {

    string t = "";  //null string          
     int strlength=s.length(); 
    if (m == s.length()-1){

    return t+s[s.length()-strlength];  //the iterator takes the place of the '1'          

    } else {                                   

              return s[s.length()-m-1] + Reverse(s, m+1); // recursive call

	}          
}                                     

bool IsPalindrome(string s) {

	string Reverse(string s, int m);
		if ( Reverse( s,  m) == word){
			return true;
		}
		else {
			return false;
		}
}

[edit]Code tags added by Hammer

string Reverse();
bool IsPalindrome();


You are calling your functions incorrectly:
1) Don't specify the return type when you call them.
2) Do provide the correct argumetns to them when you call them.
3) Do check the return value to see if they did what you want them to.

Quzah.

Use code tags when posting code
Read This

I am posting this because you did not use code tags on this thread. In the furture please use Code Tags. They make your code MUCH easier to read and people will be much more likely to help you if you do. And they'll be happy about helping you


For example:

Without code tags:

for(int i=0;i<5;i++)
{
cout << "No code tags are bad";
}

With Code Tags:

Code:

for(int i=0;i<5;i++)
{
     cout << "This code is easy to read";
}

This is of course a basic example...more complicated code is even easier to read with code tags than without.

I've added code tags for you this time. They can be added by putting [code] at the beginning of your code and [/code] at the end. More information on code tags may be found at the link in my signature. Any further questions or ways I can help please feel free to PM me.

Good Luck,

So you mean where I have

bool IsPalindrome & string Reverse in the main just have
IsPalindrome and Reverse...

your 2 and 3 points I am a little shaky on- can you elaborate a little....Do you mean that there needs be code b/t the two functions. I am new at this and my teacher talks in circles..I am a little confused.....I am not trying to be stupid......=)

Sorry guys I try to use those code tags and just when I think I post it clear I get hammered with ***code tags**** =) Again, I am sorry!!!

Your main() might look something like this:

Code:

int main(void)
{
    string  word;

    cout << " What word would you like to test to see if it is a Palindrome?" << endl;
    cin >> word;

    if (IsPalindrome(word))
        cout <<word <<" is a palindrome." <<endl;
    else
        cout <<word <<" is not a palindrome." <<endl;

    return(0);
}

Ok that helps a lot!! Thank you!!!
