How does c++ support multiple inheritance ?
C++ supports multiple inheritance, which means that a class can inherit properties from more than one base class. In order to implement multiple inheritance, C++ uses the following syntax:
class DerivedClass: accessSpecifier BaseClass1, accessSpecifier BaseClass2{ // class members and functions};
class DerivedClass: accessSpecifier BaseClass1, accessSpecifier BaseClass2
{
// class members and functions
};
In the above syntax, accessSpecifier refers to the access level of the base class, which can be either public, protected, or private.
accessSpecifier
public
protected
private
When a class is derived from multiple base classes, the class inherits all the properties of all the base classes. C++ resolves any naming conflicts that arise due to multiple inheritance by using the scope resolution operator.
It is important to note that wordle today multiple inheritance can lead to complex program designs and can also cause ambiguity issues. In order to avoid these issues, it is recommended to use multiple inheritance only when it is absolutely necessary.
C++ supports multiple inheritance by allowing a class to inherit from more than one base class. This is achieved using a comma-separated list of base classes in the class declaration. Example: #include using namespace std; class Base1 { public: void displayBase1() { cout << "Base1 function" << endl; } }; class Base2 { public: void displayBase2() { cout << "Base2 function" << endl; } }; class Derived : public Base1, public Base2 { public: void display() { displayBase1(); displayBase2(); } }; int main() { Derived obj; obj.display(); // Calls functions from both Base1 and Base2 return 0; }
Multiple Inheritance is a feature of C where a class can inherit from more than one classes. The constructors of inherited classes are called in the same order in which they are inherited. For example, in the following program, B's constructor is called before A's constructor.Reference : https://www.geeksforgeeks.org/multiple-inheritance-in-c/
