What are some use cases for std::vector in C++?
std::vector is commonly used for dynamic arrays, where the size can change during runtime. It's great for storing collections of data.
Can you give me an example of when to use std::vector?
Sure! If you're building a list of user inputs that can grow or shrink, std::vector is perfect because it manages memory automatically.
What are the advantages of using std::vector over arrays?
std::vector offers dynamic sizing, automatic memory management, and built-in functions for easy manipulation, unlike static arrays.
Are there any performance considerations I should be aware of?
Yes, while std::vector is efficient, frequent resizing can lead to performance hits. It's best to reserve space if you know the size in advance.
