What are the key features of C++11's standard algorithms?

Can you explain the key features of C++11's standard algorithms?

Sure! C++11 introduced several enhancements to the standard algorithms, including lambda expressions, which allow for inline function definitions, and the ability to use move semantics for better performance.

What are lambda expressions and how do they work in C++11?

Lambda expressions are a way to define anonymous functions directly in your code. They can capture variables from their surrounding scope and are often used for short, inline operations.

Can you give me an example of using a lambda expression with a standard algorithm?

Absolutely! For example, you can use std::sort with a lambda to sort a vector of integers in descending order like this: std::sort(vec.begin(), vec.end(), [](int a, int b) { return a > b; });.

What other improvements were made to the standard algorithms in C++11?

C++11 also added new algorithms like std::all_of, std::any_of, and std::none_of, which help in checking conditions across ranges more efficiently.
