How can I perform advanced operations on std::vector in C++?

How can I perform advanced operations on std::vector in C++?

You can perform advanced operations like sorting, searching, and modifying elements using various STL algorithms. What specific operation are you interested in?

Can you show me how to sort a vector of integers?

Sure! You can use the std::sort function from the <algorithm> header. Here's an example:

#include <vector>
#include <algorithm>

std::vector<int> vec = {5, 2, 9, 1, 5, 6};
std::sort(vec.begin(), vec.end());

This will sort the vector in ascending order.

What if I want to sort it in descending order?

You can use a custom comparator with std::sort. Here's how:

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

This will sort the vector in descending order.

Are there any other operations I should know about?

Yes! You can also use operations like std::reverse, std::unique, and std::accumulate for various tasks. Let me know if you want examples!
