Uniform initialization
Uniform initialization is C++ syntax that uses braces to initialize objects and values.
Learn C++ by Example
Brace initialization is C++ initialization syntax that uses braces to initialize objects and values.
- How it is used
- Uses brace syntax to initialize scalars, containers, random-number objects, and algorithm data consistently.
- How deep it goes
- Explains syntax, initializer-list behavior, constructor differences, and narrowing prevention, while deferring initialization's more complicated edge cases.
- Examples
- Demonstrates scalar initialization, vector construction, Pascal's triangle rows, and random prime generation.
- What you can do after
- Apply it via C++11-or-later brace syntax to initialize values and containers while detecting narrowing conversions.

100 C++ Mistakes and How to Avoid Them
Uniform initialization is C++ initialization syntax using braces that provides consistent initialization semantics and rejects narrowing conversions.
- How it is used
- Applies braces to simplify initialization and make C++ code more consistent and maintainable.
- How deep it goes
- Defines the syntax, explains its benefits, and demonstrates containers and variables, but does not detail language-resolution rules.
- Examples
- Demonstrates vector construction, count initialization, and braced defaults for Complex data members.
- What you can do after
- Apply it to initialize variables, containers, and complex objects while avoiding silent narrowing conversions.
