Hi. You can only define variables at the top of a block before any non variable-definition statements in the block. So for your code:

void *ExtractData(void *t,void *t1,void *t2)
{
pthread_t TInv,TSales,TShip;
int i;
int rc = 0;
long tid,tid1,tid2;
double result=0.0;
tid = (long)t;
tid1 = (long)t+1;
tid2 = (long)t+2;
void *Iid;
void *Sid;
void *Spid;

it throws an error when it gets to
void *lid;
because you've done something like
tid=(long)t;
before it. Reorder your code to keep your variable definitions above your statements and you'll be fine.

If variable i has the value 10, after x = 5 + (++i); the value of x after this code is 15.
True or False?
