私はイントロプログラミングを行っており、この割り当てに苦労しています。コードは次のとおりです。
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void)
{
int cardNum(int firstCard, int secondCard;
int highLow;
int score;
score = 0;
srand(time(NULL));
printf("The current card is a %d\n" ,firstCard(2,14));
printf("\n Will the next card be higher(1) or lower(2)? (press 0 to quit)");
scanf("%d" ,highLow);
if (cardNum > 1 && cardNum < 11)
{
printf ("The card is: %d ,secondCard.");
}
else if (cardNum == 11)
{
printf ("The card is: Jack");
}
else if (cardNum == 12)
{
printf ("The card is: Queen");
}
else if (cardNum == 13)
{
printf ("The card is: King");
}
else if cardNum == 14)
{
printf ("The card is: Ace");
}
{
if (highLow == 1 && secondCard > firstCard) || (highLow == 2, && secondCard < firstCard)
{
score = score + 1;
printf ("\n You have guessed correctly.");
printf ("\n Your current score is %d ,score!\n");
printf("The current card is a ("%d" ,cardOne). \n Will the next card be higher(1) or lower(2)? (press 0 to quit)");
}
else if (highLow == 1, && secondCard < firstCard) || (highLow == 2, && secondCard > firstCard)
{
score = score - 1;
printf ("The card is: %d ,secondCard.");
printf ("\n You have guessed incorrectly.");
printf ("\n Your current score is %d ,score!\n");
printf ("The current card is a %d ,cardOne.");
printf ("\n Will the next card be higher(1) or lower(2)? (press 0 to quit)");
}
else if (secondCard == firstCard)
{
printf ("\n Matching cards, no change in score");
}
else if (highLow == 0)
{
printf ("\n Thanks for playing! Your final score is %d, score.");
}
else
{
printf ("\n Incorrect input. Please enter 0, 1 or 2");
}
}
return(0);
}

乱数を作成して保存することになっていたため、宣言されていない部分については知っていますが、まだそれを理解していません（アドバイスは素晴らしいでしょう）が、主に予想される宣言指定子の広範なリストについて心配しています。どんな助けでも大歓迎です！
