What are constructors and templates in C++?

Constructors are special class functions that initialize objects. Templates allow functions and classes to operate with generic types.

Can you give me an example of a constructor?

Sure! Here's a simple example:

class MyClass {
public:
    MyClass() { // Constructor
        // Initialization code
    }
};

This constructor initializes an object of MyClass.

How do templates work in C++?

Templates enable you to write generic and reusable code. For example:

template <typename T>
T add(T a, T b) {
    return a + b;
}

This function can add two numbers of any type.

What are the benefits of using templates?

Templates promote code reusability and type safety, allowing you to write functions and classes that work with any data type.
