How do I use lists in C++?

In C++, you can use the std::list from the Standard Template Library (STL). It allows for dynamic size and efficient insertions/deletions.

Can you show me a simple example of creating and using a list?

Sure! Here's a basic example:

#include <iostream>
#include <list>

int main() {
    std::list<int> myList;
    myList.push_back(10);
    myList.push_back(20);
    myList.push_back(30);

    for (int value : myList) {
        std::cout << value << " ";
    }
    return 0;
}

What are the advantages of using lists over arrays?

Lists provide dynamic sizing, easier insertions and deletions, and can store elements of different types if you use std::list<void*>. Arrays have fixed sizes and require manual memory management.

Are there any performance considerations I should be aware of?

Yes, lists have slower access times compared to arrays due to their linked structure. Use lists when you need frequent insertions/deletions, but prefer arrays for faster access.
