Hello world!

In C, this is said as

#include <stdio.h>

int main() {
   printf("Hello World!");
   return 0;
}

In Python, this is more concisely said as

print('Hello World!')

This is a traditional greeting to novice coders from textbook writers and tutorial bloggers. There is nothing wrong with textbooks or tutorials, but there are many of them already. Hence, let this one not be another one, but do take the greeting as it is in its most literal sense.

Here is the first post of this blog.

Hello.

World.
