I saw many examples of C++ uniform initialization, but not a single initialization like x and myStruct1 in the example.

struct MyStruct{
 int a;
 int b;
};

class MyClass {
 public:
  MyClass() : 
  x{},
  myStruct1{}
  {

  }

  int x;
  struct MyStruct myStruct1;
  struct MyStruct myStruct2 = {};

};

I know that myStruct2 init is valid.
Is myStruct1 initalization valid?

tnx
