What are some common C++ OOP templates?

Can you explain what C++ OOP templates are?

C++ OOP templates allow you to create classes and functions that can operate with any data type, promoting code reusability.

Can you give me an example of a simple class template?

Sure! Here's a simple class template for a pair of values:

template <typename T>
class Pair {
private:
    T first, second;
public:
    Pair(T a, T b) : first(a), second(b) {}
    T getFirst() { return first; }
    T getSecond() { return second; }
};

How do I use this Pair class template?

You can create a Pair object like this:

Pair<int> intPair(1, 2);
cout << intPair.getFirst(); // Outputs 1

What are the benefits of using templates in C++?

Templates enhance code reusability, type safety, and can lead to more efficient code by allowing the compiler to optimize for specific types.
