Hey, just got Dark GDK yesterday, and im already completely confused

Working on a little variable program right now. I got numbers down, so i moved onto strings. My program gets a user input, and then what i WANT it do is

if string = "fart" then print "how foul"

I know thats not DGK at all, but it gets my point accross
here is my source.

+ Code Snippet

#include "DarkGDK.h"
//#include <string>
//using namespace std; 

void DarkGDK ( void )
{
dbSyncOn ( );
dbSyncRate ( 60 );


char* hello ;//= dbinput;

//void dbInput ( char* response, int iInput ) 

int greg ;
greg = 1 ;

while ( LoopGDK ( ) )
{



//hello = dbInput();
//dbPrint (hello) ;
dbPrint (hello=dbInput());

//	dbText (0, 0, hello ) ;

//dbPrint (hello) ;

if (hello == "fart") {
	 dbPrint ("how foul") ;
	 dbEnd () ;
}



dbSync ( );
}
return;
}

When I go to compile it, it runs fine. But, even if the user input is fart, it doesnt say "how foul"

Thanks in advance

This is my WIP, not even ready for a WIP thread yet though.http://smallgroupproductions.com/

hello and "fart" are both addresses to strings, what you're doing there is comparing their addresses only, if you want to compare the strings that the pointers point to, then you'd want to use 'if ( !strcmp( hello, "fart" ) )', you'll need string.h for this.

Hmm. Okay, that makes sense I guess. But when I tried to put that instead of my current if statement, it wouldnt compile. Ill try and figure it out, but help is ALWAYS welcome.

Thanks for the help already.

EDIT:
ah HA!
it has been accomplished

+ Code Snippet

if ( !strcmp( hello, "fart" )) {
	 dbPrint ("how foul") ;
	 dbEnd () ;
}

I think i was just missing the }
thank you very much good sir.
