It compiles and outputs completely fine in both Windows and the Debian client I am required to use for school, but I much prefer to develop in ubuntu.

It outputs

When I use the debugger it is all put onto the screen during deck.Print();

Answer 1

Your deck numbers start from 1 and you're referencing the num array from 0. So an i of 12 in

for(int i = 0; i <= 12; i++)//sets all the diamond cards
{
    deck[i].numValue = i+1;
    deck[i].pointValue = 0;
    deck[i].suit = DIAMOND;
}

Gives a numValue of 13 and your num array only goes to index 12. num[deck[i].numValue] should be num[deck[i].numValue - 1] .
