i want create in main "list" in this way:

int main(){
        Node list;
 }

and not in this way:

int main(){
        Node list = {1,2,NULL};
    }

    }Node = {1,2,NULL};

error C2513: 'Node' : no variable declared before '='

Answer 1

您不能在C中为结构成员提供预定义的值。请使用类似构造函数的函数或类似构造函数的宏。

Answer 2

The typedef (or struct) "statement" defines a type, not an object.

Types have no value. It only makes sense to speak of values in relation to objects.

Objects do not have a default value (other than 0 when they're implicitly initialized).

So you can't do what you want.
