How can I use advanced algorithms in C++?

You can leverage the C++ Standard Library's algorithms like std::sort, std::transform, and std::accumulate for efficient data manipulation.

Can you give me an example of using std::transform?

Sure! Here's a simple example: you can use std::transform to apply a function to each element in a vector. For instance, to square each element, you can do:

#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
}

What about using std::accumulate for summing elements?

Great question! You can use std::accumulate to sum elements in a container. Here's an example:

#include <vector>
#include <numeric>
#include <iostream>

int main() {
    std::vector<int> vec = {1, 2, 3, 4};
    int sum = std::accumulate(vec.begin(), vec.end(), 0);
    std::cout << "Sum: " << sum; // Outputs: Sum: 10
}
