我在介紹編程並且努力完成這項任務,任何幫助都將被讚賞!下面是代碼:期望的聲明說明符錯誤
#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);
}
這些錯誤:

我知道未申報的部分原因是我應該做的隨機數,並將其儲存,但我仍然還沒有很明白這一點(任何建議都會很棒),但主要是我擔心預期聲明說明符的廣泛列表。任何幫助,將不勝感激!
看這句話:'INT cardnum中(INT firstCard,INT secondCard; ' – hek2mgl
和這一行:'if(highLow == 1 && secondCard> firstCard)|| (highLow == 2,&& secondCard
Pankrates
和這一行:'else if(highLow == 1,&& secondCard firstCard)' –
