These are just some hello world programs.
They've all been manually tested to run. That's the point of hello world programs. Sometimes getting a programming language running as far as "hello world" is half the battle of starting to use it.
- C : hello.c
- Python 3 : hello.py
- Java : HelloTemplate.java
- shell : hellos.sh (gets everyone to say hello, compatible with bash)
- D : hello.d
