如上例所示, struct line 数据结构定义了一个int length变量和一个变长数组contents[0],这个struct line数据结构的大小只包含int类型的大小,不包含contents的大小,也就是**sizeof (struct line) = sizeof (int)**。 创建结构体对象时,可根据实际的需要指定这个可变长数组的长度,并分配相应的空间,如上述实例代码...
New in the C23 standard, the typeof operator is a unary operator that returns the type of an expression. It can be used in type declarations, type casts, type checks, and so on. It gets the type of a variable, function, or any C expression....
