DAVID J. MALAN: In fact,
just this past week,

2
00:00:02,470 --> 00:00:07,080
I looked in my old CS50 binder, which
I still have from some 25 years ago,

3
00:00:07,080 --> 00:00:11,160
and took a photo of what was apparently
the very first program that I

4
00:00:11,160 --> 00:00:14,850
wrote and submitted and quickly
received minus two points on.

5
00:00:14,850 --> 00:00:16,770
But this is a program
that we'll soon see

6
00:00:16,770 --> 00:00:20,610
in the coming days that does
something quite simply like print

7
00:00:20,610 --> 00:00:22,988
"Hello CS50," in this
case, to the screen.

8
00:00:22,988 --> 00:00:24,780
And to be fair, I
technically hadn't really

9
00:00:24,780 --> 00:00:27,060
followed the directions, which is
why I lost those couple of points.

10
00:00:27,060 --> 00:00:30,369
But if you just look at this, especially
if you've never programmed before,

11
00:00:30,369 --> 00:00:32,369
you might have heard about
programming languages

12
00:00:32,369 --> 00:00:34,327
but you've never typed
something like this out,

13
00:00:34,327 --> 00:00:36,030
undoubtedly it's going to look cryptic.

14
00:00:36,030 --> 00:00:38,070
But unlike human
languages, frankly, which

15
00:00:38,070 --> 00:00:42,510
are a lot more sophisticated, a lot
more vocabulary, a lot more grammatical

16
00:00:42,510 --> 00:00:46,290
rules, programming-- once you start
to wrap your mind around what it is

17
00:00:46,290 --> 00:00:48,540
and how it works and what
these various languages are,

18
00:00:48,540 --> 00:00:50,910
it's so easy, you'll see,
after a few months of a class

19
00:00:50,910 --> 00:00:54,540
like this to start teaching yourself
subsequently other languages,

20
00:00:54,540 --> 00:00:58,160
as they may come in the
coming years as well.
