An example of an AI chatbot conversation about STL vector sizes in C++.
What is the size of STL vectors in C++?
The size of an STL vector in C++ can be determined using the size() method, which returns the number of elements.
Does the size include the capacity of the vector?
No, the size() method returns the number of elements currently in the vector, while capacity() returns the total number of elements the vector can hold without reallocating.
How can I increase the size of a vector?
You can increase the size of a vector by using the resize() method, which allows you to specify the new size.
What happens if I resize a vector to a smaller size?
If you resize a vector to a smaller size, it will remove elements from the end of the vector to match the new size.
