文本到二进制 [英] text to binary
问题描述
如何将通过键盘输入的文本转换为二进制格式？
我应该先将文本的每个字母转换为ASCII然后
binary ???
这种方法是否正确？请指教。
非常感谢。
问候，
Raghu
how do i convert a text entered through keyboard into a binary format?
Should I first convert each letter of the text to ASCII and then
binary???
Is this method correct? Please advise.
Thanks a lot.
Regards,
Raghu

C并不保证你是一个键盘。大概你的意思是标准输入
stream。
C doesn''t guarantee you a keyboard. Presumably you mean the standard input
stream.
变成二进制格式？
into a binary format?
您想要哪种二进制格式？
Which binary format would you like?

您需要更加具体地了解输入的性质以及相应输出的所需特性。

You need to be a lot more specific about the nature of your input and the
desired characteristics of the corresponding output.

我的意思是通过使用scanf语句，如果我给短信（包括
只有空格而不是特殊字符）可以转换成二进制1'的
和0'。
希望现在我很清楚
Richard Heathfield写道：
I mean by using scanf statement if i give the text message (including
only spaces not special characters) can that be converted to binary 1''s
and 0''s.
Hope now i''m clear

否。短语二进制文件在C语言的背景下，这是一个非常糟糕且误导性的选择。二进制文件是CR和LF在外部介质（文件）和RAM中具有相同编码的文件。所谓的
" text"当文件被读取或写入时，文件在< CR>< LFor< LF>< CRand''\ n''之间静默转换。 （注意''n''具有与
LF相同的ASCII编码。）
什么是ASCII？这是一个正式的定义，如果你愿意，可以在拉丁字母表中的某些字形 - 和二进制代码之间进行映射。如果二进制文件没有被滥用，那么它已经是一个二进制文件。应始终保存一个完全由ASCII字符组成的
的文件，并将其作为非二进制文件检索到
。关于总是的常见警告这是一个很麻烦的词。
如果这让你感到困惑，那么在google群组上进行搜索，你会发现
较旧的帖子讨论这个问题..
No. The phrase "binary file" in the context of the C language was a very
poor and misleading choice. A binary file is one in which CR and LF have
the same encoding in an external medium (file) and in RAM. A so-called
"text" file silently transforms between <CR><LFor <LF><CRand ''\n'' when
the file is read or written. (Note that ''n'' has the same ASCII encoding as
LF.)
What is ASCII? It is a formal definition, mapping if you like, between
certain glyphs in the latin alphabet -mostly - and a binary code. It already
*is* a binary file, if the word binary is not misused. A file that consists
entirely of ASCII characters should always be saved and
retrieved as a non-binary file. With the usual caveats about "always" being
a troublesome word.
If this leaves you confused, do a search on google groups, you will find
older posts discussing this problem..
