# Objects

In C++, an object is an instance of a class. A class is a blueprint or template that defines the structure and behavior of objects. Objects are used to encapsulate data and functions (methods) that operate on that data. Here's an example of defining a class and creating objects in C++:

```cpp
#include <iostream>

// Define a simple class called "Person"
class Person {
public:
    // Constructor to initialize the object
    Person(std::string name, int age) : name_(name), age_(age) {}

    // Member function to display information about the person
    void DisplayInfo() {
        std::cout << "Name: " << name_ << ", Age: " << age_ << " years" << std::endl;
    }

private:
    // Private member variables
    std::string name_;
    int age_;
};

int main() {
    // Create objects of the Person class
    Person person1("Alice", 30);
    Person person2("Bob", 25);

    // Call member functions on objects
    person1.DisplayInfo();
    person2.DisplayInfo();

    return 0;
}
```

In the code above:

1. We define a class called `Person` with a constructor, a member function `DisplayInfo`, and private member variables `name_` and `age_`. The constructor initializes the object with a name and age.
2. In the `main` function, we create two objects, `person1` and `person2`, of the `Person` class using the constructor.
3. We then call the `DisplayInfo` member function on each object to display their information.

Objects encapsulate data (in this case, `name_` and `age_`) and the functions that operate on that data (e.g., `DisplayInfo`). Objects of the same class share the same methods but have their own unique data.
