1. ## Function

The entire code does everything I want but I can not get the results function to work properly i know its a simple error probably something with brackets but I can not figure it out.

this is the results function
Code:
```int results(struct cars *resultspointer, int size)
{

struct cars temp;
int x,y;

/* seed the randomizer */
srand( (unsigned)time(NULL));
int write=0;
int player1=0;
int player2;

/* sort the scores */
for(x=0;x<CARS_ARRAY_SIZE;x++){
for(y=x+1;y<size;y++){
if((resultspointer+x)->(distance)<((resultspointer+y)->(distance)))
{
temp = ((resultspointer+x)->(distance));
player[x] = ((resultspointer+x)->(distance));
player[y] = (resultspointer+y)->(distance);
}
}
}

/* display the results */
puts("Round Results:");
for(x=0;x<PLAYERS;x++)
{
printf("#%d %s, score %d\n",x+1);
((resultspointer+x)->(name));
((resultspointer+x)->(distance));
write=writeCarsTXT(CARS_ARRAY_SIZE, results);
}

}```

One thing I can see
Code:

scanf("%d,%d", &player1, &player2);```
Take some time to work through each error/warning

One thing I can see
Code:
```scanf("%d,%d", player1,player2);
// should be
scanf("%d,%d", &player1, &player2);```
Take some time to work through each error/warning
Yep. Write a little code, compile and run, inspect the output. Rinse and repeat...

4. got it all to work thank you
