Can you frame the question correctly? I don't understand what you meant by constructor being inherited? Do you mean to say syntactically or semantically.
Consider testing your hypotheses or resolving your questions by writing a small piece of code and checking the outcome. It's a good learning method. Code: #include<iostream> using std::cout; using std::endl; class parent { public: int x; parent () { cout << "\tThis is the parent constructor" << endl; x = 0; } }; class child: public parent { public: int x; }; class sibling: public parent { public: int x; sibling () { cout << "\tThis is the sibling constructor" << endl; x = 2; } }; int main() { cout << "Instantiating the child" << endl; child theKid; cout << "Instantiating the sibling" << endl;; sibling theBro; theKid.x = 4; cout << "Child x = " << theKid.x << endl; cout << "Sibling x = " << theBro.x << endl; return 0; }
