Ranges API
The C++ ranges API is a standard-library facility providing ranges, views, adaptors, and algorithms for processing sequences without explicit iterator pairs.
Learn C++ by Example
<ranges> is the C++ standard library header that declares ranges, views, and range adaptors.
- How it is used
- Uses views and adaptors to filter or transform containers while avoiding manual iterator tracking.
- How deep it goes
- Demonstrates drop_while, filter, pipe chaining, and validation, but does not develop adaptor internals.
- Examples
- Shows vector filtering, dropping values below three, checking nonnegative rows, and comparing iterator-based removal.
- What you can do after
- Apply it via std::views to compose readable filtering and skipping operations over containers.
100 C++ Mistakes and How to Avoid Them
The C++ ranges API is a standard-library interface for applying algorithms to ranges of elements without requiring explicit iterator pairs.
- How it is used
- Simplifies standard-library algorithm calls when sorting collections such as students.
- How deep it goes
- Explains direct range passing and readability benefits, but stops short of surveying the API or its implementation.
- Examples
- Uses student sorting by GPA as the concrete ranges example.
- What you can do after
- Apply it via the C++ standard library by supplying a container and comparison function instead of iterator pairs.
