Objects

In C++, an object is an instance of a class that encapsulates data and functionality pertaining to that data.

Suppose a class named MyClass was created, so now it can be used to create objects.

To create an object of MyClass, specify the class name, followed by the object name.

City nyc;      // Used the City class to create an object named nyc
City shanghai; // Used the City class to create an object named shanghai

To access the class attributes, use the dot syntax (.) on the object:

Create an object called myObj and access the attributes:

class MyClass {
  public:
    int myNum;
    std::string myString;
};

int main() {
  // Create an object of MyClass
  MyClass myObj;

  // Access attributes and set values
  myObj.myNum = 15;
  myObj.myString = "Some text";

  // Print attribute values
  std::cout << myObj.myNum << "\n";
  std::cout << myObj.myString;

  return 0;
}
