You havent understood the for loop and forgot the other member of your struct
for (int i = 0; i < 5; i++)
{
playerCards[i].nVal = 2;
playerCards[i].cSuit = 0; computerCards[i].nVal = 2;
computerCards[i].cSuit = 0;}
Clearer would be classes or a function
void resetCard(Card &card)
{
card.nval = 2;
card.cSuit = 0;
}
for (int i = 0; i < 5; i++)
{
resetCard( playerCards[i] );
resetCard( computerCards[i] );
}
