我正在进行入门编程并努力完成这项任务，感谢您的帮助！这是代码：
#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);
}
这些是错误：

我知道未声明的部分，因为我应该制作随机数并存储它们，但我仍然没有完全弄清楚（任何建议都会很棒）但主要是我担心预期的声明说明符的广泛列表。任何帮助，将不胜感激！
