Overriding in multiple inheritance

Question

If I have the following contracts:

contract A {
   function _delegate() internal virtual {
      //some code
   }
}

contract B is A {
   //some code not including _delegate()
}

contract C is B {
   function _delegate() internal override {
      //some code
   }
}

..and if I deploy Contract C and call _delegate(), which code will run? The one from Contract A or from Contract C?

Answer 1

In Contract A: You have the initial _delegate() function.

In Contract B: _delegate() function is inherited, from Contract A.

In Contract C: _delegate() function is inherited, from Contract B, which inherited that function from Contract A.

However, in Contract C you are overriding _delegate() function, so that code will be the valid one.

Answering your question: If you deploy Contract C and call _delegate(), you will get //some code from Contract C.
