That article is from 2003. And yeah, i'm wondering too, why?

No, that was long time ago, before .NET

Not total copy :) printf != Console.Writeline. Although they do the same thing.

Teacher: Write "I will not make paper airplanes in the classroom" 50 times on the board. Student:

for(int counter = 0; counter <=50; counter++ )
{
Console.Writeline("I will not make paper airplanes in the classroom ");
}
