Learn to use arrays! Learn to use loops! Let the computer do the work for you and save yourself a ton of typing. Haven't tested it but the following code is probably equivalent, is certainly more compact, and would be easier to maintain going forward.

#define PINCOUNT 6
const int pins[] = {7,8,9,10,11,12};


void setup ()   {
    for(int i=0;i<PINCOUNT;i++)
    {
        pinMode( pins[i], OUTPUT);
    }
}
void loop ()    
{
    for(int i=0;i<PINCOUNT;i++)
    {
        digitalWrite(pins[i], HIGH);
        if( (i-1>0) ) 
        { 
           digitalWrite(pins[i-1], LOW); 
        }
        else
        {
          digitalWrite(pins[PINCOUNT-1], LOW);
        }
        delay(500);
    }
}

Good first effort though, you're on the right track!
