How can I use C++11 std::vector for advanced data manipulation?

C++11's std::vector offers several advanced features like move semantics, initializer lists, and lambda functions. What specific manipulation are you interested in?

I'm interested in using lambda functions to sort a vector.

You can use the std::sort function along with a lambda expression. For example: std::sort(vec.begin(), vec.end(), [](int a, int b) { return a > b; }); This sorts the vector in descending order.

What about removing duplicates from a vector?

You can use std::unique in combination with std::erase to remove duplicates. First, sort the vector, then use std::unique to move duplicates to the end, and finally erase them.

Can you show me a complete example?

Sure! Here's a complete example:

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

int main() {
    std::vector<int> vec = {1, 2, 2, 3, 4, 4, 5};
    std::sort(vec.begin(), vec.end());
    auto last = std::unique(vec.begin(), vec.end());
    vec.erase(last, vec.end());
    for (int n : vec) std::cout << n << ' '; // Outputs: 1 2 3 4 5
}
