回复 216# kzl0629
我本想对付你这等级的货色就可以不用打开pdf，败给你脸皮厚度了。
算了，你要贴我就贴。
ISO C11
Clause 4(N1570)
5 A strictly conforming program shall use only those features of the language and library
specified in this International Standard.3) It shall not produce output dependent on any
unspecified, undefined, or implementation-defined behavior, and shall not exceed any
minimum implementation limit.
6 The two forms of conforming implementation are hosted and freestanding. A conforming
hosted implementation shall accept any strictly conforming program. A conforming
freestanding implementation shall accept any strictly conforming program in which the ∗
use of the features specified in the library clause (clause 7) is confined to the contents of
the standard headers <float.h>, <iso646.h>, <limits.h>, <stdalign.h>,
<stdarg.h>, <stdbool.h>, <stddef.h>, <stdint.h>, and
<stdnoreturn.h>. A conforming implementation may have extensions (including
additional library functions), provided they do not alter the behavior of any strictly
conforming program.4)
7 A conforming program is one that is acceptable to a conforming implementation.5)
8 An implementation shall be accompanied by a document that defines all implementation-defined
and locale-specific characteristics and all extensions.
3) A strictly conforming program can use conditional features (see 6.10.8.3) provided the use is guarded
by an appropriate conditional inclusion preprocessing directive using the related macro. For example:
#ifdef _ _STDC_IEC_559_ _ /* FE_UPWARD defined */
/* ... */
fesetround(FE_UPWARD);
/* ... */
#endif
4) This implies that a conforming implementation reserves no identifiers other than those explicitly
reserved in this International Standard.
5) Strictly conforming programs are intended to be maximally portable among conforming
implementations. Conforming programs may depend upon nonportable features of a conforming
implementation.
吃饭去了。
等你的读后感。别给我说看不懂中心思想。
