How do I use vectors in C++?
In C++, vectors are part of the Standard Template Library (STL). You can include the vector header and use them like arrays but with dynamic sizing.
Can you show me a simple example of declaring and initializing a vector?
Sure! You can declare a vector like this: std::vector<int> myVector;
and initialize it with values like this: std::vector<int> myVector = {1, 2, 3, 4};
.
How do I add elements to a vector after it's been created?
You can use the push_back()
method to add elements. For example: myVector.push_back(5);
will add 5 to the end of the vector.
What about removing elements?
To remove elements, you can use the pop_back()
method to remove the last element, or erase()
to remove a specific element.
