“空对”的含义括号？ [英] meaning of "empty pair" of parenthesis ?
问题描述
这是来自Steve Summit C的笔记：
空的括号表示我们的主函数接受
没有参数，也就是说，没有参数调用函数时，传入的任何信息都需要传递给b
。 [1]
我想，一个空对括号表示函数可以采用
无限数量的参数

this is from Steve Summit C notes:
The empty pair of parentheses indicates that our main function accepts
no arguments, that is, there isn''t any information which needs to be
passed in when the function is called. [1]
i think, an "empty pair" of parenthesis means a function can take
unlimited number of arguments

不在C定义中它不会。也不在声明中。

Not in a C definition it doesn''t. Nor in a declaration.

史蒂夫是正确的。 （更确切地说，我们的主函数不接受
参数。但这是一个很好的观点。）
Steve is correct. (More precisely, our main function accepts no
parameters. But it''s a fine point.)
i think，anempty对"括号意味着一个函数可以采取
无限数量的参数
i think, an "empty pair" of parenthesis means a function can take

但史蒂夫只是解释了它的含义！你有什么理由相信史蒂夫错了？

But Steve just explained what it means! What grounds do you have for
believing that Steve is wrong?

考虑：
void foo（）;
void bar（void）;
void baz（）{}
foo是一个需要的函数一个未指定数量的参数。 bar和
baz都是零参数的函数。看到差异？
（这并不是很有意义，因为它是C的历史神器。
C ++更加理智;如果你学会了C ++规则，认为它们是C规则，
你会非常困惑.C ++不是C.）

Consider:
void foo();
void bar(void);
void baz() {}
foo is a function that takes an unspecified number of arguments. bar and
baz are both functions that take zero arguments. See the differences?
(This doesn''t make perfect sense because it''s a historical artifact of C.
C++ is much saner; if you learned the C++ rules thinking they were C rules,
you''ll be very confused. C++ is not C.)
