Uniform initialization allows you to initialize an object using braces {}. When it comes to std::array, you can use uniform initialization to initialize the elements of the array directly at the time of declaration.

Here is an example of how to initialize a std::array of std::string using uniform initialization:

#include <array>
#include <string>

int main() {
    std::array<std::string, 3> myArray = { "Hello", "World", "!" };
    
    // Accessing elements of the array
    std::cout << myArray[0] << " " << myArray[1] << myArray[2] << std::endl;
    
    return 0;
}

In this code snippet, we declare a std::array called myArray of type std::string with a size of 3. We use the uniform initialization syntax {} to assign values to the elements of the array.

After initialization, we can access the elements of the array using the subscript operator []. In this case, we print the elements of the array, which yields the output: “Hello World!”.

The use of uniform initialization with std::array provides a clean and concise way to initialize the elements of the array at declaration. It avoids the need for explicit element-wise initialization, especially when dealing with larger arrays.

Overall, uniform initialization simplifies the process of initializing std::array objects and improves code readability. It is a useful feature to leverage when working with arrays in C++.
