Let’s say we have a struct defined as follows:
struct Person {
std::string name;
int age;
};
We can initialize a std::array
of Person
structs using uniform initialization as follows:
std::array<Person, 3> people = {{
{"Alice", 25},
{"Bob", 30},
{"Charlie", 35}
}};
In the above code example, we define a std::array
called people
that can store three Person
objects. Each object is initialized using a brace-enclosed list. The double braces {{ }}
are used to indicate initialization of the array, while the inner braces { }
are used for initializing each individual Person
struct.
You can add or modify the number of elements in the std::array
as needed, and provide the corresponding initializations for each struct.
Uniform initialization not only works with std::array
, but it is also supported for other container types and custom classes. This syntax provides a consistent and intuitive way to initialize objects in C++.
By using uniform initialization, you can make your code more concise and readable, especially when initializing complex data structures. It can help to improve code maintainability and reduce the chance of initialization errors.

In C++, you can initialize a `std::array` of structs using uniform initialization. Uniform initialization provides a concise and readable way to initialize objects.
