According to C++ rules, if the programmer doesn't provide any constructor, then the compiler implicitly defines a default constructor. Therefore, option C is correct. Options A and D are incorrect because even if the class doesn't have data members or already has a default constructor defined, the compiler will still define a default constructor if none are explicitly defined by the programmer. Option B is also incorrect because there is no such feature or syntax in C++ that specifies the compiler to create a default constructor.
