That’s all for vector in C++. Definitely vector in very strong linear data struct and very easy to use. In our next section we would learn about vector of vectors which can be thought of 2D array in C/C++.Was this post helpful? Let us know if this post was helpful. Feedbacks are ...

In other words, a 2D vector is a vector of 1D vector, i.e., a vector having elements as 1D vector.So what will be notation of 2D array?vector<T> arr, where T is vector<W> where, W can be any datatype like int, char etc....
