While loop help

[bmancl]

The while loop I have does what it is supposed to do but in a very round about way. I have a while loop(inside a function) that is supposed to call another function for two random numbers(1 - 6). It then checks to see if the sum of those numbers is equal to 7 or the point number which is determined earlier in the program. So basically it loops until it hits a 7 or point. When the loop runs if it is not a 7 or point right away it seems to display the same values for example:

Die 1 = 1
Die 2 = 2
You rolled a 3!
Die 1 = 1
Die 2 = 2
You rolled a 3!
.
.
.
This happens many times and then it gets new values for the dice. If they do not add up to 7 or the point value it will repeat the same message over and over. It keeps doing this until it eventually hits the 7 or point value and exits the loop. Do I need to call the rolling function differently or reset its values somehow? I am not quite sure what I am missing.

 while (still_in != 0){                                     
                                                                           
                              roll = rolling();  
                              printf("Die 1 = %d\n", roll[0]);   
                              printf("Die 2 = %d\n", roll[1]);
                              sum = roll[0] + roll[1]; 
                              printf("You rolled a %d!\n", sum);
                              if (sum == 7){
                                 start = start - bet;
                                 printf("You lose. You now have $%d.\n",start);
                                 goto LOOP;}
                              else if (sum == point){
                                 start = start + bet;
                                 printf("You win! You now have $%d.\n",start);
                                 goto LOOP;}
                             
                              }

int *rolling()
{
  static int  r[1];
  int i;
 
  srand( (unsigned)time( NULL ) );
  for ( i = 0; i <= 1; ++i)
  {
     r[i] = rand()%6+1;
  }

  return r;
}

You are reseeding the RNG everytime you call rolling. This is not necessarily. Just put it in main();

This is also a buffer overrun - there is no r[1] element.
