Constructors and Destructors

Initializing Objects Properly

class Person {
public:
    string name;
    int    age;

    // Constructor — runs automatically when object is created
    Person(string n, int a) : name(n), age(a) {}

    string greet() {
        return "Hi, I'm " + name + " (" + to_string(age) + ")";
    }

    // Destructor — runs when object is destroyed
    ~Person() {
        // clean up resources here (files, memory, etc.)
    }
};

Person p("Alice", 30);     // constructor called
cout << p.greet();         // Hi, I'm Alice (30)
// p's destructor runs when p goes out of scope

Member initializer list — preferred

Person(string n, int a) : name(n), age(a) {}
// More efficient than assigning inside the body

Your Task

Create a BankAccount class with constructor (string owner, double balance), and methods:

• void deposit(double amount)
• bool withdraw(double amount) — returns false if insufficient funds
• double getBalance()
