00:00:00,690 --> 00:00:02,530
SPEAKER: CS50 starts
in Scratch, of course,

3
00:00:02,530 --> 00:00:05,820
to give students a taste of what you
can do with programming, especially

4
00:00:05,820 --> 00:00:09,160
without the distraction of syntax
like parentheses and semicolons,

5
00:00:09,160 --> 00:00:09,760
and the like.

6
00:00:09,760 --> 00:00:12,060
But we then focus
quite a few weeks on C,

7
00:00:12,060 --> 00:00:14,670
an older, more traditional
text-based language

8
00:00:14,670 --> 00:00:17,310
that really gives students a
sense of how computers and how

9
00:00:17,310 --> 00:00:19,320
programs work from the bottom up.

10
00:00:19,320 --> 00:00:22,440
But it's a language in which it's
very time consuming, if not difficult,

11
00:00:22,440 --> 00:00:23,820
to solve certain problems.

12
00:00:23,820 --> 00:00:27,930
And so we eventually introduce languages
like Python, which are higher level, so

13
00:00:27,930 --> 00:00:31,020
to speak, that make it much
easier to solve certain problems,

14
00:00:31,020 --> 00:00:33,120
but they take for granted
that you do hopefully

15
00:00:33,120 --> 00:00:36,950
understand what's going
on underneath the hood.

16
00:00:36,950 --> 00:00:41,000
