When should I use vectors in C++?

When should I use vectors in C++?

You should use vectors in C++ when you need a dynamic array that can grow or shrink in size, providing flexibility.

What are the advantages of using vectors over arrays?

Vectors offer automatic memory management, bounds checking, and built-in functions for easy manipulation, unlike static arrays.

Can you give me an example of using a vector?

Sure! Here's a simple example: std::vector<int> numbers = {1, 2, 3}; numbers.push_back(4); This adds 4 to the vector.

Are there any performance considerations I should be aware of?

Yes, while vectors are efficient for most operations, frequent resizing can lead to performance overhead. Reserve space if possible.
