在printf()中转换为二进制 [英] conversion to binary in printf()
问题描述
我在printf格式字符串中意外键入%b而不是%d
并获得了该数字的二进制表示。是标准C
还是编译器扩展?

%b不是标准转换说明符。

它在lcc-win32编译系统中用于二进制表示
也许其他printfs也这样做。 />

这是一个扩展名。它不太可能是*编译器*扩展,
但是; printf是运行时库的一部分。这是一个重要的
区别;例如,gcc使用系统上可用的任何运行时库。

我们必须做点什么。这是事情。因此,我们必须这样做。
I accidentally typed %b instead of %d in a printf format string
and got a binary representation of the number. Is that standard C
or a compiler extension?

David Marsh a écrit :I accidentally typed %b instead of %d in a printf format string and got
a binary representation of the number. Is that standard C or a compiler
extension?It is used in the lcc-win32 compiler system for binary representation
Maybe other printfs do that too.

compiler extension?It''s an extension. It''s not likely to be a *compiler* extension,
though; printf is part of the runtime library. This is an important
distinction; gcc, for example, uses whatever runtime library is
available on the system.

We must do something. This is something. Therefore, we must do this.
