#include <iostream>

//iterate through a string to check if it's a palindrome

}
}
cout << "Largest palindrome: " << palin << " (" << l_val << "*" << r_val << ")";
cin.get(); //so you can see the results--press ENTER to exit

system("pause");
return 0;
}

above is my code, please can someone explain to me how to do a flow chart for this and also explain what part is doing what

thanks
above is my code, please can someone ... explain what part is doing what
That doesn't make any sense.
