Question

如何在Brainfuck中使用循环打印1到10的数字？这可能吗？
我正在寻找这个问题的解决方案。

Answer 1

++++++++++++++++++++++++++++++++++++++++++++++++ Let address 0 be the digit we want to print, starting with '0'
>++++++++++ Let address 1 be our newline character
>+++++++++ Let address 2 be our counter, starting at 9 
[
  - Decrement the counter
  <<+. Increment the digit we want to print and print it
  >. Print the newline
  > Make sure we're at the counter again before we loop back
]

<< Move back to address 0
--------. Make address 0 '1'
-. Make address 0 '0'

为了在BrainF**k中编程，假装每个程序（即使是简单的程序）都需要从布局开始。

这方面的伪代码如下所示：

Generate the character '0'
Move left and generate '\n'
Move left and generate the counter (10 numbers in this case)
Loop: Get back to the character '0', print it, increment it to '1', go to the newline, print it, go to the counter, and decrement it. End it when the counter is 0
Generate '1' and print it
Generate '0' and print it

然而，最后两个步骤可以简化为：

Go back to the digit '9'
Decrement it until '1' and print
Decrement it until '0' and print

这样可以节省大量时间和 字节 字符。

要生成字符“0”，需要生成整数48（因为它是ASCII值）。要做到这一点，你可以去Esolangs的BF常量。查找数字48，我们发现 -[

到目前为止，我们的程序是-[

接下来，向左移动并生成\n（换行符）。我们可以使用

到目前为止，我们的程序是-[

然后，向左移动并生成计数器。我们希望计数器为10，以打印从0到9的数字<代码>

到目前为止，我们的程序是-[

之后，启动循环[。转到'0'

到目前为止，我们的程序是-[

最后，转到'9'

程序完成了。

+++++++++++++++++++++++++++++++++++++++++++++++++  Cell 0 to '1'
>++++++++++  cell 1 to '\n'
>+++++++++  cell 2 to 9 as counter
[  Print numbers 1 to 9
<<  Data pointer to cell 0
.+  Print and increment cell 0
>.  Data pointer to cell 1 and print the newline
>-  Data pointer to cell 2 and decrement counter
]  Loop till counter is 0
+++++++++  Set cell 2 to 9
[  Set cell 0 to '1'
<<-  Data pointer to cell 0 and decrement
>>-  Data pointer to cell 2 and decrement counter
]  Loop till counter is 0
<<.  Data pointer to cell 0 and print '1'
-.   Decrement cell 0 and print '0'
>.   Data pointer to cell 1 and print newline
