43) How many parameters does a default constructor require? a. 1 b. 2 c. 0 d. 3

c. 0.

A default constructor is a constructor that can be called with no arguments. It is used to initialize the object's data members to default values. In C++, a default constructor can be defined without any parameters, like this:

class MyClass {
public:
    MyClass() {
        // constructor code here
    }
};

This constructor takes no parameters and initializes the object's data members to their default values.
