Multiple inheritance allows a class to inherit from more than one base class. This feature can enhance code reusability and design flexibility. However, it introduces complexity, especially with the diamond problem. This occurs when two base classes have a common derived class. C++ addresses this issue through virtual inheritance.
Here’s an example:
“`cpp
#include
using namespace std;
class A { public: void display() { cout << "Class A" << endl; } };
class B { public: void show() { cout << "Class B" << endl; } };
class C : public A, public B {};
int main() {
C obj;
obj.display(); // Access method from Class A
obj.show(); // Access method from Class B
return 0;
}
```
In this code, class C inherits from both A and B. This allows access to methods from both base classes. Multiple inheritance can reduce code duplication and foster reusable designs. However, careful design is crucial to avoid confusion and maintainability issues.
In summary, multiple inheritance offers both advantages and challenges. Use it judiciously to ensure clarity and prevent ambiguity in your code.
