Does the constructor of a struct initialize the fields to defaults?

class aa{

    public int j=8;
    int f;

    public aa() {
        f=99;
    }

}

struct  bb {

    public int v = 7;
    int l;

    public bb() {
        l = 88;
    }

}

I am kind of confused as I am learning about the structs.

let's say if I create an instance of class aa, is the field j initialized to 8 which is NOT done by the constructor ? and field f is first defaulted to 0, again NOT by the constructor and then initialized to 99 in a constructor

And let's say if I create an instance of struct bb, is the v initialized to 7 which is NOT done by the constructor? And field l is FIRST defaulted to 0 NOT but the constructor? And then initialized to 88 by the constructor

For both Class and Struct, the Inline initializer initializes the value then and there before the constructor is called.
public int j=8; // is not dependent on constructor.
When you create an object of Class or Struct with the new keyword then the constructor is called and for both class and struct, the constructor initializes all the uninitialized members to their default values or to the value you set inside the constructor. However, the initialized values using an inline initializer can also be overridden inside the constructor.
