What are some examples of std::transform in C++11?

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

Sure! std::transform is used to apply a function to a range of elements and store the result in another range.

Can you give me a simple example?

Of course! Here's a basic example: You can use std::transform to square each element in a vector.

How would the code look for that?

Here's a snippet:

#include <vector>
#include <algorithm>
#include <iostream>

int main() {
    std::vector<int> vec = {1, 2, 3, 4};
    std::vector<int> result(vec.size());
    std::transform(vec.begin(), vec.end(), result.begin(), [](int x) { return x * x; });
    for (int n : result) std::cout << n << ' '; // Outputs: 1 4 9 16
}
