To initialize a std::deque using uniform initialization, you can make use of the brace initialization syntax {} introduced in C++11. Here’s an example:
std::deque<int> myDeque = {1, 2, 3, 4, 5}; // Initialize with values 1, 2, 3, 4, 5
In the above code snippet, we declare a std::deque called myDeque and initialize it with the values 1, 2, 3, 4, and 5 using uniform initialization syntax. This initializes the std::deque with the provided elements in sequential order.
Uniform initialization not only allows you to initialize the std::deque with explicit values but also works for initializing with default values or empty initialization:
std::deque<int> emptyDeque{}; // Initialize an empty deque
std::deque<std::string> defaultInitializedDeque(5); // Initialize deque with five default-constructed elements
In the first example, an empty std::deque called emptyDeque is initialized using the empty curly braces {}.
In the second example, a std::deque called defaultInitializedDeque is initialized with five default-constructed elements. The size of the deque is specified within the parentheses, and each element is default-initialized.
Uniform initialization improves code clarity and allows for consistent initialization syntax across different types of initialization. It is a modern and preferred method of initializing containers, including std::deque, in C++. Embrace this feature to make your code more readable and maintainable.
