I have a text file containing the following information:

# Map

# Small islands with treasure in the NW corner and start in the SE corner.

M

5

o$...

oo...

#..o.

..oo.

....@

I want to read in the file but want to ignore the comments at the top (they begin with #). There can be infinite amount of comments. I want to store the letter (M) in a char variable, and the number as the map size. The following characters represent a treasure map, and I want to read that into a vector of vectors. How should the code look to accomplish this? I am writing the code in C++.
