What are structs and templates in C++?

Can you explain what structs are in C++?

Sure! Structs in C++ are user-defined data types that group related variables together. They are similar to classes but default to public access.

How do I define a struct?

You can define a struct using the struct keyword followed by the struct name and its members. For example: struct Person { std::string name; int age; };

What about templates? How do they work?

Templates in C++ allow you to create functions or classes that can operate with any data type. You define a template using the template keyword.

Can you give me an example of a template function?

Certainly! Here's a simple example: template <typename T> T add(T a, T b) { return a + b; } This function can add two values of any type.
