How does std::transform work in C++11?

Can you explain how std::transform works in C++11?

Sure! std::transform is a standard algorithm that applies a function to a range of elements and stores the result in another range.

What are the parameters for std::transform?

It takes two input iterators, an output iterator, and a unary or binary operation. The first two iterators define the range to transform.

Can you give me a simple example?

Of course! Here's a basic example: std::transform(vec.begin(), vec.end(), result.begin(), [](int x) { return x * 2; }); This doubles each element in vec.

What if I want to use a binary operation?

You can use two input ranges. For example: std::transform(vec1.begin(), vec1.end(), vec2.begin(), result.begin(), std::plus<int>()); This adds corresponding elements from vec1 and vec2.
