推荐答案

语录:我需要帮助使Jack，Queen和King的值等于10，而不是(如我的程序中的11、12、13)

怎么样:

Quote: I need help to make the values of Jack, Queen, and King equal to 10 and not (11,12,13 as in my program)

How about:

if (value > 10) value = 10;

至于另外一个，您只需要检查玩家的总和是否超过21就可以将其保留为A，并将Ace的值重置为1.或者为玩家提供一个决定的选项.

As to the other one, you just need to check whether the player holds an Ace if his total goes above 21, and reset the Ace value to 1. Or offer an option for the player to decide.

关于另一个，只要他的总分超过21，您只需检查玩家是否持有A，并将Ace的值重置为1.或者提供一个选项供玩家决定."

我如何让玩家做出决定?或编写if语句以使Ace在超过21岁时破产?

"As to the other one, you just need to check whether the player holds an Ace if his total goes above 21, and reset the Ace value to 1. Or offer an option for the player to decide."

how do i make the player decide? or write the if statement for the Ace to bust if over 21?
