• default initialization

• uniform initialization C++ uniform initialization (introduced in C++11) is the use of curly braces {} to initialize variables, objects, and containers, providing a consistent, unified syntax across all types.

Braced-Init-List Syntax (Introduced in C++11):

T object{arg1, arg2};

Technically called direct-list-initialization. It is more consistent than parentheses and solves several issues:

• Prevents Narrowing: Braces do not allow implicit narrowing conversions (e.g., double to int), making it safer.
• Solves Ambiguity: Braces cannot be mistaken for a function declaration, avoiding the most vexing parse.
• Initializes Containers: Allows direct construction of containers like std::vector with a list of values.

Разница с std::initializer_list

• braced-init-list: Это синтаксис (фигурные скобки и значения внутри), сам по себе не имеет типа.
• std::initializer_list: Это тип стандартной библиотеки, который компилятор автоматически создает, когда видит список внутри фигурных скобок, если целевой объект ожидает этот тип.
