Cannot get PAIR::big to just display greater number

Hi,

Appreciate any help. My code compiles... builds.... executes just fine. Only problem I'm having is... I cant figure out how to get PAIR::big() to simply print out the larger #. When I execute... it displays... the Larger # like I want... but then for some reason it displays the smaller number next to it. I want to get rid of the smaller #.

Any suggestions?

Thanks Mike

 int PAIR::big()

else 
{
return b;

}
The reason is that there is no temporary variable to accept the bigger value returned by the "big()" function and hence you end up printing the original value of your object "e". So you can write something like this:

C++ Syntax (Toggle Plain Text) 
  1. int big = e.big () ;
  2. cout << "\nThe bigger number is " << big ;

Hope it helped, bye.
I don't accept change; I don't deserve to live.
