Programming is telling your computer how
to do something.
Large tasks must be broken up into smaller
tasks, which must be broken up into still
smaller tasks, down until you get to the
most basic tasks that you don’t have to
describe, the tasks your computer already
knows how to do. (These are really basic
things such as arithmetic or display-ing
some text on your screen.)

Matz's philosophy
(Yukihiro Matsumoto – the
creator of Ruby)
Ruby is designed to make
programmers happy
public class HelloWorld {
public static void main(String []args) {
System.out.println("Hello World");
} // close main
} // close class
#include <iostream>
#include <string>
using namespace std;
int main(){
cout << "Hello World" << endl;
return 0;
} // close main
puts ' Hello World'
Ruby program is short
A program is not built;
it is grown.
Avoid duplication
(DRY rule: Don’t Repeat
Yourself)
