More C++ Ranges Please - Roi Barkan - CppCon 2023

Discover how to leverage the C++ ranges library to simplify complex problem-solving, break down systems into manageable layers, and combine components to achieve efficient solutions.

Key takeaways

So, breaking down a system into different layers can help reduce complexity and allow for easier maintenance.
Ranks can be thought of as dimensions or lengths of sequences, and understanding these ranks can help with problem-solving.
The ranges library in C++ provides many useful algorithms and data structures for working with sequences and ranges.
Thinking about libraries as building blocks can help with problem-solving and make it easier to combine different components together.
The idea of “going and catching rabbits” - or looking at other people’s code and trying to abstract it - can be a useful way to generate ideas and learn from others.
When designing APIs, it’s important to think about the preconditions and postconditions of different functions and algorithms.
The use of regular and algebraic data types can help simplify code and make it more maintainable.
The ranges library has the advantage of being able to take ideas from other languages and incorporate them into the standard.
There are many places where you can go to find ideas and solutions to problems, and it’s worth taking the time to explore and learn from others.
When writing code, it’s important to think about the problem you’re trying to solve and what kind of algorithm or data structure you need to use to solve it.
The idea of “permutation” - or rearranging a sequence of elements - can be a useful concept in problem-solving.
The ranges library provides many different algorithms and data structures for working with sequences and ranges, and understanding these different components can help with problem-solving.
When designing libraries, it’s important to think about the API and how different components will be used together.
There are many different ways to solve a given problem, and it’s worth exploring different approaches to find the one that works best.
The idea of “ranks” - or dimensions or lengths of sequences - can be a useful concept in problem-solving.
The use of projections can help simplify code and make it more maintainable.
The idea of “value semantics” - or the concept that objects have a specific value - can be a useful concept in problem-solving.
When writing code, it’s important to think about the problem you’re trying to solve and what kind of algorithm or data structure you need to use to solve it.
The ranges library provides many different algorithms and data structures for working with sequences and ranges, and understanding these different components can help with problem-solving.
