c - C中常量的奇怪声明

Question

我真的不明白这里有什么区别

const int a = 1;
int const a = 1;

我知道常量是什么，但上面的例子让我很困惑。

Answer 1

没有区别。两者相同。

n1570 草案:6.7.2 类型说明符:

Type specifiers are void, char, short, int, long, float, double, signed, unsigned, _Bool, _Complex, <struct-or-union-specifier>, <enum-specifier>, and <typedef-name>.

At least one type specifier shall be given in the declaration specifiers in each declaration, and in the specifier-qualifier list in each struct declaration and type name. Each list of type specifiers shall be one of the following multisets (delimited by commas, when there is more than one multiset per item); the type specifiers may occur in any order₁, possibly intermixed with the other declaration specifiers.
