我正在尝试编写一个包含一些if语句的循环，循环的问题是用户将输入一个选项H或{{1} }。但是，当用户输入S时，程序会直接进入S语句并经过该语句，之后会转到另一个语句。
让我告诉你代码：
H因此，当我输入int decision(struct CardDeck *deck) {
char choice;
printf("Value is %d\n", deck->ValueOfSecondPlayer);
while (deck->ValueOfSecondPlayer <= 21)
{
if (deck->ValueOfSecondPlayer == 21) {
printf("Blackjack!");
}
if (deck->ValueOfSecondPlayer > 21) {
printf("Sorry, you lose");
}
if (deck->ValueOfSecondPlayer < 21) {
printf("Would you like to hit or stand?\n");
scanf("%c", &choice);
}
if (choice == 'H' || choice == 'h'); {
printf("You wish to hit; here's your card\n");
deck->ValueOfSecondPlayer += printCards(deck);
printf("Your total is now %d\n", deck->ValueOfSecondPlayer);
}
if (choice == 'S' || choice == 's') {
printf("You wished to stay\n");
break;
}
}
}
时，我得到的输出是：
S当我输入Value is 18
Would you like to hit or stand?
S
You wish to hit; here's your card
Jack of Clubs
Your total is now 28
You wished to stay
Pess any key to continue . . .
时，程序运行如下：
H所以我的问题是，即使我使用Value is 16
Would you like to hit or stand?
h
You wish to hit; here's your card
4 of Clubs
Your total is now 20
Would you like to hit or stand?
You wish to hit; here's your card
2 of Spades
Your total is now 22
Press any key to continue . . .
或H，该程序仍会选择h和S。
如果有人能告诉我我做错了什么以及如何解决问题，我将不胜感激！
