What are some examples of dynamic arrays in different programming languages?

Dynamic arrays are data structures that can grow and shrink in size. In languages like Python, you can use lists, while in C++, you can use vectors. Would you like to see specific code examples?

Yes, please provide examples in Python and C++.

In Python, you can create a dynamic array like this:

my_list = []
my_list.append(1)
my_list.append(2)

In C++, you can use vectors:

#include <vector>
std::vector<int> myVector;
myVector.push_back(1);
myVector.push_back(2);

What about Java and JavaScript?

In Java, you can use ArrayList:

import java.util.ArrayList;
ArrayList<Integer> myList = new ArrayList<>();
myList.add(1);
myList.add(2);

In JavaScript, arrays are dynamic by default:

let myArray = [];
myArray.push(1);
myArray.push(2);
