View 2D Vector C++

View 2D Vector C++. In c++, vectors are called dynamic arrays that have the capability to automatically resize itself when an item is inserted or removed, with its storage being controlled automatically by the container. Assuming you are familiar with a normal vector in c++, with the help of an example we demonstrate how a 2d vector differs from a normal vector below:

I'a trying to implement an algorithm, i want to input element by the user into 2d vector so that i have an element like this:

While (!is.eof ()) { is >> item; 1 , 1 , 1 , 1 1 , 1 , 1 , 1 1 , 1 , 1 , 1 1 , 1 , 1 , 1 1 , 1 , 1 , 1. Submitted by includehelp, on june 16, 2019 2d vector in c++ stl. I also tried the following code but i didn't get any help:
