Question

I am trying to see if a the second character is equal to an 1, J, Q, K, or A. I then want to set a Boolean for each of these cases. This is a blackjack program am writing.

The deck is dealt and a single card is evaluated
Card is a string that a given a random value from an array of cards, the value would be something like “HK”

bool delt1 = card[1].Equals("1");
bool deltJ = card[1].Equals("J");
bool deltQ = card[1].Equals("Q");
bool deltK = card[1].Equals("K");
bool deltA = card[1].Equals("A");

But I receive an “Index was outside the bounds of the array” error

any suggestion?

Answer 1

This will probably fix your problem but you likely have others:

bool delt1, deltJ, deltQ, deltK, deltA;
if (card.Length >= 2)
{
    delt1 = card[1].Equals('1');
    deltJ = card[1].Equals('J');
    deltQ = card[1].Equals('Q');
    deltK = card[1].Equals('K');
    deltA = card[1].Equals('A');
}
else
    throw new Exception("Not enough characters in card to perform this check");
