How can I modify collections in C++?

In C++, you can modify collections like vectors, lists, and maps using various methods. What specific collection are you interested in?

I'm interested in vectors. How do I add and remove elements?

To add elements to a vector, you can use the push_back() method. To remove elements, you can use pop_back() or the erase() method. Would you like examples?

Yes, please provide examples for both adding and removing elements.

Sure! To add an element: myVector.push_back(10); and to remove the last element: myVector.pop_back();. For removing a specific element, use myVector.erase(myVector.begin() + index); where index is the position of the element.

Thanks! What about sorting a vector?

You can sort a vector using the std::sort() function from the <algorithm> header. Just call std::sort(myVector.begin(), myVector.end()); to sort it in ascending order.
