An example of an AI chatbot conversation about C++ vector usage and examples.
What are some examples of using vectors in C++?
Vectors in C++ are dynamic arrays that can grow in size. For example, you can create a vector of integers like this: std::vector<int> numbers;.
Can you show me how to add elements to a vector?
Sure! You can add elements using the push_back method. For example: numbers.push_back(10); will add 10 to the end of the vector.
How do I access elements in a vector?
You can access elements using the index operator. For example, numbers[0] will give you the first element in the vector.
What about removing elements?
You can remove elements using the pop_back method to remove the last element, or erase to remove a specific element.
