At work, part of my job is to manage PBX (Private Branch Exchange) phone systems whenever the need arises. For those who don’t know what a PBX phone system is, think about your experience when calling a business.

If you’re interested you can read more about PBX here on Wikipedia.

During the last Fall semester I participated in CUNYCodes, a portfolio development program. The mission of CUNYCodes is to help create an environment for college students majoring in STEM related fields or are just interested in learning software development to work collaboratively and expose us to best practices and get a better insight to the industry. I had a great experience and the rest of my post is about what I would do if I could go back in time.

I’ve been working on implementing my own data structures for practice, and I decided I’d try to make my own std::array.

What caught me off-guard however was the size of the executable Hello World program below.
