How to Implement the Solution

At long last, here's Hello World in C*.

As we can see, Hello World in C* looks similar to C. That said, C* is a superset of C, so this shouldn't be too much of a surprise. At any rate, let's dig in.

Unlike C, there is no include statement. As far as I can tell, the language does not actually have an include statement or header files. Somehow, the compiler know where to pull the definition for standard libraries.

Next, we have our usual main function declaration which serves as the drop in function for our program. We should be used to seeing this convention since it's common in the popular industrial languages like C++ and Java.

Finally, we make a call to println which is a special print function that outputs the specified string with a newline character. Of course, all we're going to pass to it is the "Hello, World!" string. And, that's it!

How to Run the Solution

The compiler source can be found in the C* GitHub repository. To build it, just follow the build from source instructions for your particular OS. Once, you've built the compiler, download a copy of the Hello World in C* sample. Then, build and run the program like this:

cx -o hello-world hello-world.cx
./hello-world
