Access to class members

[jewameb621]

To access class members, the `.` (dot) and `->` (arrow) operators are used for objects and pointers to objects, respectively.

```cpp
obj.myField = 10; // Assign a value to the field
obj.printValue(); // Call the
``` method

Inheritance and Polymorph

Example of inheritance afghanistan telegram data and polymorphism:

```cpp
class Animal {
public:
virtual void speak() {
cout << "Animal makes a sound" << endl;
}
};

class Dog : public Animal {
public:
void speak() override {
cout << "A dog barks" << endl;
}
};

class Cat : public Animal {
public:
void speak() override {
cout << "A cat meows" << endl;
}
};

int main() {
Animal animals[] = {new Dog(), new Cat()};
for (int i = 0; i < 2; i++) {
animals->speak(); // Calling the speak method using polymorphism
delete animals;
}
return 0;
}
```

In this example, the `Dog` and `Cat` classes inherit from the `Animal` base class, and they override the `speak` method. When using polymorphism, calling the `speak` method through a base class pointer calls the appropriate version of the method on each object.

Conclusion


This is just the beginning of your journey into object-oriented programming in C++. OOP provides powerful tools for creating complex and structured programs, and with the right knowledge and practice, you can create high-quality software. Learn the basics, practice, and experiment - these are the key steps to mastering C++ and OOP.
