Hello++

Hello++ or Hello Plus Plus is an improvement to the Hello programming language, created by Propeng on Sunday, the 14th of March, 2010 at about 6 PM GMT.

Hello++ will print out "Hello World" whenever it encounters 'h' or 'H'. It ignores all other characters silently.

Quine
Unlike the original Hello, it is possible to produce a Quine using Hello++.

Hello World

Compiler
There is a Hello++ compiler in C# here.

Interpreter
And you can't forget Zayne's interpreter. It's an improved version of his Hello interpreter i = input("Enter Command: ") if i != 'h': if i != 'H': print("") if i == 'H': print("Hello World") else: print("Hello World")
