Advantages of Using Methods Instead of Free Functions
# Easier to maintain
   Methods keep related operations inside the class, making the program more organized and easier to update.
# Better data protection
   A method can control how the object's data is changed and prevent invalid changes.
# Simple to use
    Methods can be called using dot notation, such as account.deposit(100), which makes the code easy to read.
# Hides unnecessary details
    Users only need to know what a method does and how to call it. They don't need to understand all the code inside it.
# Keeps data and behaviour together
    A class can contain both the information about an object and the methods that work with that information.
# Can be reused with different objects
    Once a method is defined in a class, objects created from that class can use the same method.
# Allows rules to be enforced
    Methods can make sure that data is changed in a safe and valid way. For example, a withdraw() method could prevent a bank account from having a negative balance.
In short: methods are useful because they make code more organized,
reusable, easier to understand, and safer to manage, especially when working with objects and their data.
