Two Dimensional vector assignment issues.

[ktmdude3]

Hello! I'm new to C++ and I have an interesting assignment for class that , honestly I have no clue where to start. We are working with two dimensional vectors for this assignment. One of the functions that I am supposed to write uses a two dimensional vector that has a set number of rows and columns that is received from standard input. However in the function we need to modify the 2d vector by adding borders around the set rows and columns. I'm not sure how to even start this so any help would be great to start this.

Thanks!
