line 8: don't you see something a little strange about that line? hint: () and ;

>>int main ();
Of course not -- get rid of the semicolon!

You need to add { and } when there are more than 1 lines within while statements

 C++ Syntax (Toggle Plain Text) 
while( <condition> )
{
   // some lines here
}
else
{
    // more lines here
}
while( <condition> )

}
else
{
    // more lines here
}

braces are still wrong -- they are backwards and the closing } is on the wrong place. Re-read my previous post again. You need to count the number of opening and closing braces and make sure there is a } for every { (and vice versa)

line 11: delete the semicolon at the end of that while statement

This is how to format the code. I also change a couple of other errors -- you had << and >> reversed. cout uses << and cin uses >>, you have them backwards.

>>if(password == Enter Password)
That is also wrong but I don't know how you need to correct it.

>>if(password == Enter Password)

Should be testing for secondnumber
if(password == secondnumber)
