Arduino上的struct：function（）'未命名类型'

Question

I write a struct for variable and function, but is not work for me. I'm confused...

struct Array2 {
    int array[2] = {0, 1};
};

Array2 Digit2Arr2(int x) {
  Array2 v;
  if (x > 9) {
    int y;
    y=x/10; v.array[1]=x-(10*y); x=y;
    y=x/10; v.array[0]=x-(10*y); x=y;
  } else {
    v.array[0] = 0;
    v.array[1] = x;
  }
  return v;
}

'Array2' does not name a type

Highly recommend you read up on how to create structs.

Heres somewhere you can start:

Your syntax is wrong in the creation of the struct.

struct Array2 {
   int array[2] = {0, 1}; 
};
