What are some real-world examples of encapsulation in C++?

Encapsulation in C++ is about bundling data and methods that operate on that data within a class. A real-world example is a bank account class that encapsulates account details and methods like deposit and withdraw.

Can you explain how encapsulation improves code security?

Certainly! Encapsulation restricts direct access to some of an object's components, which helps prevent unintended interference and misuse of the data. This is achieved by using access specifiers like private and protected.

Are there any specific industries where encapsulation is particularly useful?

Yes, encapsulation is particularly useful in industries like finance, healthcare, and software development, where data integrity and security are crucial.

Can you give me a code example of encapsulation in C++?

Sure! Here's a simple example:

class BankAccount {
private:
    double balance;
public:
    BankAccount() : balance(0) {}
    void deposit(double amount) { balance += amount; }
    void withdraw(double amount) { if (amount <= balance) balance -= amount; }
    double getBalance() { return balance; }
};
