I’m coding in C++ and I’m in need for a dynamic data storage, like ArrayList in C# or Java.
Can anyone help me with that? I’m not sure what to use.
Thanks!

You are looking for
std::vector. You can read here about it (scroll down on that page to view a description of its functions).Vectors have constant-time lookup. Insertion/removal is fast at the end of a vector, but (as the link I posted explains in more detail) is slower otherwise. Additionally, vectors have to be resized as you store additional data in them, so it is worth looking into
reserve(this is like ArrayLists’ensureCapacity). Note that this resizing is automatic –reserveis there only for performance reasons.
