int playCards(int, int);

int main()

{

int card1, card2, result;

srand(time(NULL)); /* seed random number generator */

card1 = 3 + rand() % 5; /* random number between 3 and 7 */

printf("Press any key to be dealt your first card\n");

getch();

printf("Your first card is a %d\n\n", card1);

printf("Press any key to be dealt your second card\n");

getch();

{

card2 = 3 + rand() % 5; /* random number between 3 and 7 */

}

while (card2 == card1); /* must not be same as first card */

printf("Your second card is a %d\n\n", card2);

result = playCards(card1, card2);

if (result)

{

printf("You won :)");

}

else

{

printf("You lost :(");

}

printf("\n\n");

system("pause");

return 0;

}

int playCards(int card1, int card2)

{

int sum = card1 + card2;

printf("The sum of your cards is %d\n\n", sum);

if (sum < 10) return 1;

return 0;

}
