When should I use a vector in C++11?

When should I use a vector in C++11?

You should use a vector in C++11 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, dynamic resizing, and built-in functions for easy manipulation, unlike static arrays.

Are there any performance considerations I should be aware of?

Yes, while vectors are generally efficient, frequent resizing can lead to performance overhead. It's best to reserve space if you know the size in advance.

Can I store different data types in a vector?

No, vectors in C++ are type-specific. If you need to store different types, consider using a vector of pointers or a variant type.

What about using vectors in multithreading?

Vectors are not thread-safe by default. You should use synchronization mechanisms like mutexes when accessing them from multiple threads.
