You see in the beginning just after the #include... where it gives all those variables the const qualifier. I don't understand why there there? i removed them and nothing happened? Maybe someone could explain there meaning to me. thanks
Code:
// cards.cpp
// demonstrates structures using playing cards
#include <iostream.h>
const int clubs = 0;
const int diamonds = 1;
const int hearts = 2;
const int spades = 3;
const int jack = 11;
const int queen = 12;
const int king = 13;
const int ace = 14;
struct card
{
int number; // 2 to 10, jack, queen, king, ace
int suit; // clubs, diamonds, hearts, spades
};
void main()
{
card temp, chosen, prize; // define cards
int position;
card card1 = { 7, clubs }; // initialize card1
cout << "Card 1 is the 7 of clubs\n";
card card2 = { jack, hearts }; // initialize card2
cout << "Card 2 is the jack of hearts\n";
card card3 = { ace, spades }; // initialize card3
cout << "Card 3 is the ace of spades\n";
prize = card3; // copy constthis card, to remember it
cout << "I'm swapping card 1 and card 3\n";
temp = card3; card3 = card1; card1 = temp;
cout << "I'm swapping card 2 and card 3\n";
temp = card3; card3 = card2; card2 = temp;
cout << "I'm swapping card 1 and card 2\n";
temp = card2; card2 = card1; card1 = temp;
cout << "Now, where (1, 2, or 3) is the ace of spades? ";
cin >> position;
switch (position)
{
case 1: chosen = card1; break;
case 2: chosen = card2; break;
case 3: chosen = card3; break;
}
if(chosen.number == prize.number && // compare cards
chosen.suit == prize.suit)
cout << "That's right! You win!\n";
else
cout << "Sorry. You lose.\n";
}
