1 00:00:00,480 --> 00:00:02,910 Let's learn another important key term. 2 00:00:03,600 --> 00:00:05,340 Well, too, for that matter. 3 00:00:06,020 --> 00:00:10,040 One is expressions and the other one is statements. 4 00:00:10,220 --> 00:00:12,890 You're going to hear this a lot when talking to programmers. 5 00:00:12,890 --> 00:00:14,390 So what do they mean? 6 00:00:14,840 --> 00:00:15,740 Let's have a look. 7 00:00:16,190 --> 00:00:18,270 If we create a piece of code here. 8 00:00:18,290 --> 00:00:23,180 Let's just say IQ is 100, IQ has lowered. 9 00:00:23,510 --> 00:00:31,220 And then let's say user H is going to equal IQ divided by five. 10 00:00:32,049 --> 00:00:35,710 An expression, is this part of the code? 11 00:00:36,560 --> 00:00:41,690 It's a piece of code that produces a value. 12 00:00:42,110 --> 00:00:44,690 In our case, this produces a value, right? 13 00:00:44,690 --> 00:00:49,430 Because 100 divided by five is going to equal 20. 14 00:00:49,850 --> 00:00:57,800 So this is an expression, a statement, on the other hand, is an entire line of code. 15 00:00:57,860 --> 00:01:05,720 Not this entire thing, but an entire line of code that performs some sort of action in this case. 16 00:01:05,720 --> 00:01:07,400 What action are we performing? 17 00:01:07,850 --> 00:01:15,350 Well, the action is that we're calculating a 100 divided by five and then assigning that value to the 18 00:01:15,350 --> 00:01:17,140 variable user h. 19 00:01:17,510 --> 00:01:20,360 So this is an expression. 20 00:01:21,110 --> 00:01:23,360 This is a statement. 21 00:01:24,050 --> 00:01:26,990 And also this is another statement. 22 00:01:27,750 --> 00:01:33,570 So if you hear me mentioning these terms throughout the course, hopefully now you know what they mean. 23 00:01:34,200 --> 00:01:35,250 I'll see you the next one. 24 00:01:35,520 --> 00:01:36,120 Bye bye.
