Website to Demonstrate Skills

So, I'm looking for a good web hosting service (free preferably) where I can demonstrate my programming skills. I would like one where I can have programs written in C/C++, Java, and C# run from and communicate with the client host. If it ended up being something like how geocities was a long time go, then it would look like that would be impossible.

So, I would like to find a web hosting service that would give me as much freedom as I would have as if I ran these applications on my own computer.

You can definitely find such web hosts just you have to search for good web hosts on the net, read their reviews and can opt their services with the specifications you want.
