便携式意味着它将在许多平台上编译。
要实现这一目标,您需要某种标准。
ANSI / ISO C标准为C
程序创建了一种可移植性。
Posix是另一种标准。如果没有Posix
假设,它可以标准化一些附加的
标准。
http://en.wikipedia.org/wiki/POSIX
没有这样的作为Windows C的东西。有些C编译器在Windows上运行
。 Mingw海湾合作委员会,微软和英特尔都制作了不错的C编译器
for Windows。

便携式C是否比posix C快。
我的意思是说便携式C是否直接转换为汇编
语言....避免任何中间转换? ??

便携式C是否与posix C一样快。
便携性和速度没有真正的联系。

通常,最好的优化器会在几次传递中处理文件。
what is the difference between portable C, posix C and windows C ???

To accomplish this, you need some kind of a standard.
The ANSI/ISO C standard creates one kind of portability for C
programs.
Posix is another kind of standard. It allows some additional
fascilities to be standardized that will not work without the Posix
assumption.

There is no such thing as Windows C. There are C compilers that run
on Windows. Mingw GCC, Microsoft and Intel all make nice C compilers
for Windows.

HTHDoes portable C is as faster as posix C.
I mean to say that does portable C is converted directly to assembly
language....avoiding any intermediate conversion ???

Does portable C is as faster as posix C.Portability and speed have no real connection.
I mean to say that does portable C is converted directly to assembly
language....avoiding any intermediate conversion ???Generally, the best optimizers process the file in several passes.
