How do I use structs in C++?

In C++, a struct is a user-defined data type that allows you to group variables of different types together. You can define a struct like this:

struct Person {
    std::string name;
    int age;
};

You can then create an instance of the struct and access its members.

Can you show me an example of creating and using a struct?

Sure! Here's an example:

struct Person {
    std::string name;
    int age;
};

int main() {
    Person person1;
    person1.name = "Alice";
    person1.age = 30;

    std::cout << person1.name << " is " << person1.age << " years old.";
    return 0;
}

What are the differences between structs and classes in C++?

The main difference is that members of a struct are public by default, while members of a class are private by default. Additionally, structs are typically used for plain data structures, while classes are used for more complex data types with methods.
