You have a typical array overrun.
I guess your initial value for (*iPtr) is 1, right?

Now look at your code:

void dealFive(int wDeck[][13],int hand[5][2], int *iPtr)
{
...
...

for (;(*iPtr)<((*iPtr)+5); (*iPtr)++)

I'm not sure what you want to do, but your condition is definitely wrong because the value "iPtr" points to will always be smaller than the same value + 5...
