What is the C++11 std::transform function?

Can you explain what the std::transform function in C++11 does?

Sure! The std::transform function applies a given function to a range of elements and stores the result in another range.

How do I use std::transform with a lambda function?

You can use it like this: std::transform(begin, end, output, [](const auto& elem) { return elem * 2; }); This doubles each element.

What are the parameters for std::transform?

It takes two input iterators (begin and end), an output iterator, and a unary operation (or binary operation for two ranges).

Can std::transform work with different input and output types?

Yes, it can! Just ensure that the output iterator can accept the type returned by the operation.
