1 00:00:00,540 --> 00:00:02,650 Hello and welcome in this field you. 2 00:00:02,700 --> 00:00:10,820 I'm going to illustrate with some basic examples what output means in programming. 3 00:00:11,130 --> 00:00:22,620 What is an output and how pulled is basically anything that comes out of a computer after it has been 4 00:00:22,620 --> 00:00:24,210 processed. 5 00:00:24,240 --> 00:00:31,450 So a typical example or B this slide you are looking at on the screen the monitor. 6 00:00:31,500 --> 00:00:36,670 Here's an example of an output device that is used to. 7 00:00:36,690 --> 00:00:48,420 I'll put text on the screen to illustrate I want you to open up your web browser and typing in the address 8 00:00:48,420 --> 00:00:49,180 bar. 9 00:00:49,410 --> 00:00:52,520 About call on blank. 10 00:00:52,620 --> 00:01:01,980 And that will keep you this blank page once you open up the blank page just right click anywhere and 11 00:01:01,980 --> 00:01:03,590 click on inspect. 12 00:01:04,980 --> 00:01:09,160 And click on console and this console area. 13 00:01:09,160 --> 00:01:19,100 Here is where we are going to do some experimentation with output so I'm going to use some built in 14 00:01:19,430 --> 00:01:29,910 commands of functions that I've built in to javascript functions are bunch of code or computer state 15 00:01:29,910 --> 00:01:36,800 measures that do specific things so the functions are already been built in and then baked into the 16 00:01:37,250 --> 00:01:38,980 javascript programming language. 17 00:01:38,990 --> 00:01:42,000 We just have to call them to use them. 18 00:01:42,210 --> 00:01:50,160 So the first thing I wanted to warn to this play and I'll put here inside this area here. 19 00:01:50,300 --> 00:01:56,720 I want to write him a message so to do that I I'm going to use a command. 20 00:01:56,950 --> 00:02:01,760 Source and another function called the document. 21 00:02:02,810 --> 00:02:05,160 Right. 22 00:02:07,860 --> 00:02:17,100 And inside the parentheses is where you specify the message that you want to be displayed on the screen. 23 00:02:17,570 --> 00:02:21,290 So I want the message to be big. 24 00:02:21,530 --> 00:02:33,290 So I'm going to use and hate one element we've sent which is an hastey AML hedin tag so I'm one of two. 25 00:02:33,810 --> 00:02:34,430 Hello 26 00:02:36,880 --> 00:02:39,060 world. 27 00:02:40,730 --> 00:02:42,480 Exclamation mark. 28 00:02:44,440 --> 00:02:49,940 Close the hate one tag. 29 00:02:49,980 --> 00:02:51,520 All right. 30 00:02:52,260 --> 00:02:59,810 And they're that close the parent this is Apple the semicolon. 31 00:02:59,810 --> 00:03:04,590 So this here is a complete statement in Jabr scrip. 32 00:03:04,760 --> 00:03:13,850 So what I'm seeing here this right here is a method in OIF function that basically is going to write 33 00:03:14,150 --> 00:03:17,110 this message here to the coroner document. 34 00:03:17,120 --> 00:03:19,900 This here is a current document. 35 00:03:19,910 --> 00:03:23,530 So who's going to print out this message. 36 00:03:23,640 --> 00:03:26,630 A world there is an alcoholic then closing quote. 37 00:03:26,630 --> 00:03:31,230 Is it because they had text so you need to enclose text in quotes. 38 00:03:31,250 --> 00:03:33,310 So they refer to us as string. 39 00:03:33,590 --> 00:03:38,630 So if I press Enter NOW was displayed in this period. 40 00:03:38,780 --> 00:03:42,060 Hell you want to let me do that. 41 00:03:42,060 --> 00:03:45,530 So this here is an output. 42 00:03:45,710 --> 00:03:51,790 It's regarded as an output sore because a computer has taken used this method here. 43 00:03:51,800 --> 00:03:56,400 This command then printed this text on the screen. 44 00:03:56,420 --> 00:04:00,830 So this is an output from this action. 45 00:04:00,830 --> 00:04:03,290 The computer or the program took. 46 00:04:03,500 --> 00:04:04,940 Let's try another common. 47 00:04:04,940 --> 00:04:13,870 This is another command also is called an alert is used to display pop pop messages on the screen. 48 00:04:14,360 --> 00:04:22,310 So let me do a simple Mat's out of seven blocks. 49 00:04:22,580 --> 00:04:28,340 8 You always have to end it in semicolon. 50 00:04:28,550 --> 00:04:31,720 That indicates that this is a complete statement. 51 00:04:31,730 --> 00:04:34,770 And this Deadmen enter here what they do. 52 00:04:34,780 --> 00:04:43,220 This alert is it's a built in function in Javascript is used to display bop bop messages. 53 00:04:43,490 --> 00:04:51,110 So if I press enter it will give me an output displayed in a pop up message to give me the result of 54 00:04:51,110 --> 00:04:51,680 this too. 55 00:04:51,680 --> 00:04:57,970 So our press centre can see here's givin me me I'll put off 15. 56 00:04:58,220 --> 00:05:04,010 So is done this is done the calculation and generated an output which is 15. 57 00:05:04,010 --> 00:05:07,960 So this here is known as an alert bop bop box. 58 00:05:08,120 --> 00:05:12,940 So that again Sunday sample off an output I can do one more. 59 00:05:12,950 --> 00:05:17,280 I can display a message here in a console this era. 60 00:05:17,280 --> 00:05:21,430 Here's a console so I can do console lock. 61 00:05:21,500 --> 00:05:30,700 This is another method or another function consider log and inside the parentheses. 62 00:05:31,400 --> 00:05:34,820 I can display a message and see 63 00:05:37,150 --> 00:05:41,220 that just do a similar message just say yo. 64 00:05:42,260 --> 00:05:48,810 Okay do surrounded by quotes because it's a text. 65 00:05:48,900 --> 00:05:55,290 You always have to enclose text in either single quotes or double quote. 66 00:05:55,300 --> 00:05:57,410 But you can't mix the quotes. 67 00:05:57,530 --> 00:06:00,700 You can't have a single quote here and then a double quote here. 68 00:06:00,710 --> 00:06:02,270 The quotes must match. 69 00:06:02,480 --> 00:06:10,990 So if I press enter to print out you'll on this console you can see here's printed out your console 70 00:06:11,000 --> 00:06:11,390 to the. 71 00:06:11,390 --> 00:06:13,450 This is an output. 72 00:06:13,550 --> 00:06:23,690 This here is an output so thus some basic examples or art puts an output is basically the outcome of 73 00:06:23,840 --> 00:06:27,710 the results that you've asked the computer to do. 74 00:06:27,710 --> 00:06:29,820 So you tell the computer to do something. 75 00:06:29,830 --> 00:06:33,390 He's done it and then he gives you back the results. 76 00:06:33,470 --> 00:06:37,430 So it is a result that is known as the output. 77 00:06:37,430 --> 00:06:47,590 I hope this video has helped to make you understand what he output or an output is in computer programming. 78 00:06:47,930 --> 00:06:49,190 Thank you for watching. 79 00:06:49,190 --> 00:06:50,200 Bye for now.
