basic - 我不知道我在 Just BASIC 上运行的这段代码有什么问题

Question

[Start]
n=INT((RND*10)+1)
PRINT "I have thought of a number."
PRINT "Try to guess it!"
PRINT "Enter your guess."
INPUT g

[Right]
IF g=n THEN GOTO [Finish]
**IF g < n PRINT "Your guess was wrong. Try again. The correct answer was "; n;"." THEN GOTO [Start]
IF g > n PRINT "Your guess was wrong. Try again! The correct answer was "; n;"." THEN GOTO [Start]**

[Finish]
PRINT "Well done! You guessed it."
END

Answer 1

IF condition THEN positive ELSE negative

然而，这

IF g > n THEN PRINT "Your guess was wrong. Try again! The correct answer was "; n;"."; GOTO [Start]

不会做你想做的，因为 IF...THEN...ELSE 语句在打印之后结束，随后的 GOTO 将在任何一种情况下运行。

在大多数 BASIC 中，您可以这样做：

IF g > n THEN 
  PRINT "Your guess was wrong. Try again! The correct answer was "; n;"."; 
ELSE
  GOTO Start
END IF

但我不确定你的特殊口味。

Answer 2

虽然它可以用更少的 GOTO 来编写，但这也应该有效：

[Start]
n=INT((RND*10)+1)
PRINT "I have thought of a number."
PRINT "Try to guess it!"
PRINT "Enter your guess."
INPUT g

[Right]
IF g=n THEN GOTO [Finish]

PRINT "Your guess was wrong. Try again. The correct answer was "; n;"."     
GOTO [Start]

[Finish]
PRINT "Well done! You guessed it."
END
