Answer 1

You only want to add one value to sum each loop and you haven't use done to end loop. I see 2 options if you follow the instructions that i has to be incremented before use. I didn't test them but think I didn't miss anything.

Option 1
void setup()
{
done=0; //to make sure it is false
sum=0;
i=0;
}
void loop()
{
i++;
sum=sum+data[i-1];
if (i==10) done=1;
}

Option 2
void setup()
{
done=0; //to make sure it is false
sum=0;
i=-1; //start i at -1 to avoid subtraction in indexing
}
void loop()
{
i++;
sum=sum+data[i]; //index changed to just i
if (i==9) done=1; //check changed to 9
}
