What are some examples of C++ OOP templates?

Can you give me some examples of C++ OOP templates?

Sure! C++ OOP templates allow you to create classes and functions that can operate with any data type. For example, a simple template for a stack class could look like this:

template <typename T>
class Stack {
private:
    std::vector<T> elements;
public:
    void push(const T& element) { elements.push_back(element); }
    void pop() { elements.pop_back(); }
    T top() const { return elements.back(); }
};

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

Templates promote code reusability and type safety. You can write a function or class once and use it with different data types without rewriting code.

Can you show me a more complex example?

Absolutely! Here's a template function for sorting an array:

template <typename T>
void sort(T arr[], int size) {
    std::sort(arr, arr + size);
}

This function can sort arrays of any type that supports comparison.

How do templates differ from regular functions?

Templates are defined with a placeholder type, allowing them to work with any data type, while regular functions are defined for specific types.
