C++ identifying a palindrome (output error)

[mr.me]

I had a homework assignment that wanted me to write a function that would determine whether a five digit integer was a palindrome or not

When I run the program I enter the palindrome there is no output for my if/else statement. What did I do wrong? Code Below

#include <iostream>
using std::endl;
using std::cout;
using std::cin;

main ()

{

int number; 
int a,b,c,d,e;

cout<< "I will take a digit five digit interger and indentify whether or not it is palindrome...";
cout<< "Please enter the number you want to check!\n"endl;
cin>> number;    // a = (number % 10);      
b = (number % 100) / 10;
c = (number % 1000) / 100;
d = (number % 10000) / 1000;
e = (number % 100000) / 10000; //Compare a to e and b to d. You don't need c

if (a==e && b==d)
    cout<<"The number is a palindrome!\n";
else 
    cout<< "The number is not a palindrome!\n";

return 0;

}

If I try to compile that I get an obvious error in the second cout statement. If you fix that, I think it will work fine.

Thanks

I never got an error message and couldn't get it to run proper so it tried using a different compiler
and fixed the error .
