Lesson 2.1 Classes and Objects

• In C++, everything is associated with classes and objects, along with their attributes and methods
• In real life, a car can be considered an object with attributes like weight and color, and methods like drive and brake
• Attributes and methods in classes are essentially variables and functions that belong to the class, often referred to as "class members"
• A class is a user-defined data type that serves as a blueprint for creating objects
• To create a class in C++, use the class keyword
• Example:

  • Create a class named "MyClass" with attributes myNum (int variable) and myString (string variable)
• An object in C++ is created from a class
• To create an object of a class like MyClass, specify the class name followed by the object name
• To access class attributes (like myNum and myString), use the dot syntax (.) on the object
• Example:

  • Create an object named "myObj" and access its attributes
• In the provided code snippet:

  • An object of MyClass named myObj is created
  • The attributes myNum is set to 15 and myString is set to "Some text"
  • The attribute values are printed using cout
