How do I use the std::sort algorithm in C++11?

To use std::sort in C++11, include the <algorithm> header and call std::sort with the range of elements you want to sort.

Can you show me a code example?

Sure! Here's a simple example:

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

int main() {
    std::vector<int> vec = {5, 2, 9, 1, 5, 6};
    std::sort(vec.begin(), vec.end());
    for (int n : vec) {
        std::cout << n << ' ';
    }
    return 0;
}

What if I want to sort in descending order?

You can use a custom comparator. For descending order, you can do:

std::sort(vec.begin(), vec.end(), std::greater<int>());
