What are the differences between C++ standard algorithms?

Can you explain the differences between the C++ standard algorithms?

Sure! The C++ standard library provides a variety of algorithms, such as sort, find, and accumulate. Each serves different purposes.

What are the key differences between std::sort and std::stable_sort?

The key difference is that std::sort is not stable, meaning it may change the order of equal elements, while std::stable_sort preserves their order.

When should I use std::for_each instead of a range-based for loop?

Use std::for_each when you need to apply a function to each element in a collection, especially if the function is complex or requires additional parameters.

Can you give an example of using std::accumulate?

Certainly! std::accumulate can be used to sum up elements in a vector like this: std::accumulate(vec.begin(), vec.end(), 0);.

Are there performance differences between these algorithms?

Yes, performance can vary based on the algorithm's implementation and the data structure used. For example, std::sort is generally faster than std::stable_sort.
