What is the difference between function templates and class templates in C++?

What is the difference between function templates and class templates in C++?

Function templates allow you to create a generic function that can operate on different data types, while class templates enable you to define a blueprint for a class that can also work with different data types.

Can you give me an example of each?

Sure! A function template might look like this: template <typename T> T add(T a, T b) { return a + b; }. A class template could be: template <typename T> class Box { T value; public: Box(T v) : value(v) {} };.

When would I use one over the other?

Use function templates when you need a reusable function for various types, and class templates when you want to create a generic class that can handle different types of data.

Are there any limitations to using templates?

Yes, templates can lead to code bloat if overused, and debugging template errors can be more complex due to their generic nature.
