In C++, you can use the std::array container to store a fixed-size collection of objects. One convenient way to initialize an std::array is by using uniform initialization syntax. This makes the code more concise and readable.

Uniform initialization allows you to initialize objects using curly braces {}. This syntax can also be used to initialize the elements of an std::array of std::classes.

Consider the following example where we have an std::array of std::string objects:

#include <array>
#include <string>

int main() {
    std::array<std::string, 3> names{"Alice", "Bob", "Charlie"};
    
    // Accessing and printing the elements of the array
    for (const auto& name : names) {
        std::cout << name << std::endl;
    }
    return 0;
}

In the above code, we are initializing an std::array named names of type std::string with three elements. The elements are initialized using uniform initialization syntax, where each element is enclosed within curly braces {}.

After initializing the std::array, we can access and print each element using a range-based for loop.

Output:

Alice
Bob
Charlie

Uniform initialization also works for more complex classes. Consider the following example where we have an std::array of a custom Person class:

#include <array>
#include <string>

class Person {
public:
    Person(std::string name, int age) : name_(name), age_(age) {}
    
    std::string getName() const { return name_; }
    int getAge() const { return age_; }
    
private:
    std::string name_;
    int age_;
};

int main() {
    std::array<Person, 2> people{{"Alice", 25}, {"Bob", 30}};
    
    // Accessing and printing the elements of the array
    for (const auto& person : people) {
        std::cout << "Name: " << person.getName() << ", Age: " << person.getAge() << std::endl;
    }
    return 0;
}

In the above code, we define a Person class with a name and age as member variables. The Person class has a constructor to initialize these variables. We then create an std::array named people of type Person, and initialize its elements using uniform initialization syntax.

We can access and print the elements of the array using a range-based for loop, and calling the appropriate member functions of the Person class.

Output:

Name: Alice, Age: 25
Name: Bob, Age: 30

Using uniform initialization for initializing std::array of std::classes helps to make the code more concise, readable, and easily maintainable.
