Your code is indeed a disaster, but if you're new at this i think that stoned_coder's code is a little to advanced try this instead:

Code:
#include <iostream>
#include <string>
using namespace std;

int main()
{
   string password="tiger";

   cout << "Enter Password:"
   cin >> password;

   if(password=="tiger")
   {
      cout << "Password is correct";
   }
   else
   {
      cout << "Password is incorrect";
   }


   return 0;
}
