ISO的原因;警告 [英] Reason for ISO ; warning
问题描述
[警告] ISO C不允许在功能之外额外添加'';''
int n ;;
int main（无效）
{
....
}
任何人都要关心我为什么ISO C不允许这样做，但
显然是ANSI c99吗？

int n ;;
这是一个对象定义，
后跟一个看似空的陈述。
int main（void）
{
...
任何人都在关心为什么ISO C不允许这样做，
语句只允许在函数定义中。
但显然ANSI c99呢？
我不太了解C99。

任何人都可以告诉我为什么ISO C不允许这样做，
这是语法。我认为你的意思是C90，因为......
但显然ANSI c99呢？
....这里你的意思是ISO C99。 ANSI没有批准修订后的标准，直到
2000，所以它是ANSI C2000，或者，如果你愿意的话，ANSI C00。
我没有不知道C99中的某个功能允许执行代码。
C& V？

对象的外部定义是可执行代码。

[Warning] ISO C does not allow extra '';'' outside of a function
int n;;
int main(void)
{
....
}
Anyone care to enlighten me as to why ISO C does not allow this, but
apparently ANSI c99 does?

That''s an object definition,
followed by what looks like an empty statement.
int main(void)
{
...
}
Anyone care to enlighten me as to why ISO C does not allow this,
Statements are only allowed inside of function definitions.
but apparently ANSI c99 does?
I don''t know so much about C99.

Anyone care to enlighten me as to why ISO C does not allow this,
It''s the grammar. I presume you mean C90, because...
but apparently ANSI c99 does?
....here you mean ISO C99. ANSI didn''t ratify the revised Standard until
2000, so it''s ANSI C2000 or, if you prefer, ANSI C00.
I wasn''t aware that executable code was allowed outside a function in C99.
C&V?

External definitions of objects are executable code.
