What are some real-world uses of template programming?

Template programming is widely used in C++ for creating generic and reusable code. It allows developers to write functions and classes that work with any data type.

Can you give me an example of a template in C++?

Sure! A common example is a template function for sorting an array. You can define a template function like this:

template <typename T>
void sort(T arr[], int size) {
    // Sorting logic here
}

This function can sort arrays of any type, such as integers or strings.

What are the benefits of using template programming?

The main benefits include code reusability, type safety, and reduced code duplication. It also allows for more flexible and maintainable code.

Are there any downsides to using templates?

Yes, some downsides include increased compilation times and potential code bloat, as templates can generate multiple versions of the same function for different types.
