1 00:00:01,540 --> 00:00:09,130 OK, so now we are back to A.J. and our quote from the Variables Lecture, we have a list of data that 2 00:00:09,130 --> 00:00:12,070 we will use and create variables based on that. 3 00:00:12,700 --> 00:00:13,150 All right. 4 00:00:13,150 --> 00:00:14,410 Let's jump right into that. 5 00:00:15,040 --> 00:00:16,870 So let's start with bitts. 6 00:00:17,500 --> 00:00:22,700 Before that, the laid line we created in the last lecture, this one. 7 00:00:23,440 --> 00:00:27,380 So the first one was the number of seats, which was five, I guess. 8 00:00:27,820 --> 00:00:37,210 So as I showed you in the variables lesson data type, variable name equals value and a semicolon at 9 00:00:37,210 --> 00:00:38,020 the end of the line. 10 00:00:38,710 --> 00:00:40,210 So Boyte. 11 00:00:42,210 --> 00:00:55,210 Number of seats and as you can see, I'm using Camil case here equals five and a semicolon. 12 00:00:55,770 --> 00:00:56,680 So that's it. 13 00:00:56,920 --> 00:00:57,730 It is easy. 14 00:00:57,870 --> 00:01:01,070 Let's define other variables to a tip. 15 00:01:01,320 --> 00:01:09,300 It is really easy to duplicate lines with Control Plasty or Almac Command plus DB, but you can use 16 00:01:09,300 --> 00:01:10,740 copy paste here to. 17 00:01:11,950 --> 00:01:23,080 OK, three bite type attributes were on the side, so control plasty and hand number of those. 18 00:01:25,600 --> 00:01:27,340 It was three. 19 00:01:29,910 --> 00:01:33,210 And number of vehicle owners. 20 00:01:38,510 --> 00:01:39,350 Which was one. 21 00:01:41,370 --> 00:01:43,080 And emmissions taka. 22 00:01:45,430 --> 00:01:49,370 Changing the name mission sticker. 23 00:01:50,470 --> 00:01:58,470 It was for now, let's move on to shorts, only thing is changing here is the day to type. 24 00:01:58,480 --> 00:02:03,760 So first, short power. 25 00:02:05,660 --> 00:02:16,400 Equals three hundred and sixty two and a semicolon, you can use power or power in kilowatts as variable 26 00:02:16,400 --> 00:02:18,900 name, it is really up to you. 27 00:02:19,760 --> 00:02:21,910 The next one is horsepower. 28 00:02:21,920 --> 00:02:28,240 So doubling this line, horse power with uppercase. 29 00:02:28,250 --> 00:02:35,690 And it was four hundred and ninety two then CO2 emission. 30 00:02:35,870 --> 00:02:43,970 In case of CO2, we can use numbers in the variable name, but you can also use letters so you can type 31 00:02:43,970 --> 00:02:44,750 in two. 32 00:02:45,410 --> 00:02:46,910 It's really up to you again. 33 00:02:47,240 --> 00:02:48,290 Both correct. 34 00:02:48,500 --> 00:02:51,050 So doubling this line and here. 35 00:02:52,680 --> 00:03:07,740 CO2 emission equals and it was 333 and last shorthair cubic capacity, so doubling this line again, 36 00:03:08,550 --> 00:03:11,310 deleting this part. 37 00:03:15,760 --> 00:03:27,910 And it was six thousand four hundred seventeen, OK, in the end, we had price and mileage, so here 38 00:03:28,420 --> 00:03:38,440 and price equals twenty nine thousand nine hundred and ninety nine and a semicolon and doubling the 39 00:03:38,450 --> 00:03:41,980 Seline mileage. 40 00:03:42,590 --> 00:03:50,470 And it was for thirteen thousand nine hundred and ninety nine. 41 00:03:51,690 --> 00:03:58,080 That's it here, we're going to add an extra thing, we are going to create a long for registration 42 00:03:58,080 --> 00:04:07,770 number when you start creating long and the beginning is the same, so long registration 43 00:04:09,510 --> 00:04:17,320 number equals a lot of numbers and a semicolon. 44 00:04:17,700 --> 00:04:22,350 So when you're finished with adding some extra numbers and a semicolon, you realize that something 45 00:04:22,350 --> 00:04:22,980 is not OK. 46 00:04:23,430 --> 00:04:31,440 The problem here is that when you create a long you have to add an hour to the end, uppercase or lowercase, 47 00:04:31,440 --> 00:04:32,580 you can use both. 48 00:04:32,700 --> 00:04:39,020 But I recommend you to use uppercase because lowercase l looks very similar to one. 49 00:04:39,600 --> 00:04:43,980 So adding an hour here will remove this threat underline. 50 00:04:44,910 --> 00:04:45,550 That's it. 51 00:04:45,810 --> 00:04:51,600 So the reason why we have to add Al, to the long numbers will be explained later. 52 00:04:51,750 --> 00:04:59,070 For now, I can say that the full data type for whole numbers as end and for floating point numbers 53 00:04:59,070 --> 00:05:02,110 is double in case of long and float. 54 00:05:02,490 --> 00:05:06,250 We have to tell Jova the exact data type of the number. 55 00:05:06,570 --> 00:05:12,210 It's a bit simplified, but don't worry, I will make it all clear so we are almost done. 56 00:05:12,480 --> 00:05:19,650 Let's define floating point numbers so we have three float values combined, urban and exurban fuel 57 00:05:19,650 --> 00:05:20,390 consumption. 58 00:05:20,730 --> 00:05:35,340 So here float fuel consumption combined equals and it was fifteen point five. 59 00:05:35,730 --> 00:05:42,820 And we have to add an F here and a Samwick on the next one as urban. 60 00:05:43,500 --> 00:05:56,630 So removing this combined and replacing with urban and changing the number to twenty one point four 61 00:05:57,210 --> 00:06:00,340 and one more the extra urban. 62 00:06:00,480 --> 00:06:09,720 So adding extra hair and changing this wire to thirteen point six. 63 00:06:10,840 --> 00:06:16,570 So as you can see, I changed the order of the words, the reason is that this way it is easier to read 64 00:06:16,570 --> 00:06:20,160 and see that the variables are connected to each other. 65 00:06:21,170 --> 00:06:28,970 OK, I know we didn't have double on the website, but let's define one, we are still the precise average 66 00:06:28,970 --> 00:06:30,010 fuel consumption. 67 00:06:30,290 --> 00:06:41,300 So here double fuel consumption, size average. 68 00:06:43,030 --> 00:06:48,970 Equals and 15 points and a lot of random numbers. 69 00:06:50,940 --> 00:06:58,590 And a semicolon, we can manipulate the number and define how many times we would like to multiply or 70 00:06:58,590 --> 00:07:06,070 divide it with ten to do that, let's put an E and a number to the end of the number. 71 00:07:06,480 --> 00:07:13,300 So adding E one and dividing the number with ten. 72 00:07:14,220 --> 00:07:21,960 So this way, one point five will give us the same number and doing it the opposite way. 73 00:07:22,470 --> 00:07:25,410 Just adding a negative here. 74 00:07:27,070 --> 00:07:29,080 We still have the same number. 75 00:07:29,500 --> 00:07:33,640 OK, now leave it as it is just to prove that this works properly. 76 00:07:34,180 --> 00:07:35,260 OK, just a side note. 77 00:07:35,410 --> 00:07:38,290 It works only with double and float. 78 00:07:38,710 --> 00:07:41,910 Now, let's move on to more variables left. 79 00:07:41,920 --> 00:07:44,070 One is Boolean is damaged. 80 00:07:44,620 --> 00:07:45,790 So here. 81 00:07:47,610 --> 00:08:02,280 Bullion is damaged, equals two and a CHA for energy efficiency. 82 00:08:04,660 --> 00:08:05,410 Category. 83 00:08:08,230 --> 00:08:10,510 Equals simple court. 84 00:08:11,390 --> 00:08:18,230 And in a simple code, while Dodge Challenger is not the best in saving the environment and I think 85 00:08:18,230 --> 00:08:24,560 the worst level is, gee, so I will give it a G here and a semicolon. 86 00:08:24,830 --> 00:08:31,430 OK, so finally we defined all our variables and as you can see, all of them are gray because they 87 00:08:31,430 --> 00:08:35,020 are not used anywhere, but it will change very soon. 88 00:08:35,330 --> 00:08:37,760 So in a new line here. 89 00:08:39,600 --> 00:08:47,280 Start typing in system that Baudot Branton or use as or your team and hit enter, I'm going to go that 90 00:08:47,280 --> 00:08:47,520 way. 91 00:08:47,520 --> 00:08:55,940 So s o u t and one prints a string to system that out appears and it is selected, hit, enter. 92 00:08:56,250 --> 00:08:59,940 And now as you can see, it is replaced with system that Outbrain time. 93 00:09:00,690 --> 00:09:05,040 So double codes here 2000 18. 94 00:09:06,320 --> 00:09:06,920 Dorje. 95 00:09:08,350 --> 00:09:19,120 Challenger, SRT, three hundred and ninety two, so doubling this line. 96 00:09:20,340 --> 00:09:25,710 And instead of this text, let's replace it with price. 97 00:09:27,150 --> 00:09:35,610 Colin Espace and Euro Mark, you can also add it to the end of the text, I will show you how and here 98 00:09:35,790 --> 00:09:45,030 after the double cotes plus and just stop and the variable name price and when it appears hit, enter. 99 00:09:45,720 --> 00:09:46,780 OK, that's it. 100 00:09:47,190 --> 00:09:52,390 Now, as you can see, prices here and price here is not great anymore. 101 00:09:52,830 --> 00:10:01,170 You can also add another tax to the end of this by using plus again, double quotes and you can type 102 00:10:01,170 --> 00:10:05,580 in euro if you cannot find the euro key on your keyboard. 103 00:10:06,740 --> 00:10:09,290 OK, you know, I think this here. 104 00:10:10,220 --> 00:10:16,220 And now let's move on to the next one, which is mileage, so doubling this line again. 105 00:10:16,520 --> 00:10:22,650 And is the price going to have mileage and. 106 00:10:23,790 --> 00:10:32,190 Here, mileage plus double quotes and KM or Mars, it is really up to you. 107 00:10:32,820 --> 00:10:36,270 OK, now the next line is is damaged. 108 00:10:37,540 --> 00:10:46,600 So here they call is damaged, damaged 109 00:10:48,760 --> 00:10:58,210 corn, and here instead of milage and this text is damaged, registration number and cubic capacity 110 00:10:58,210 --> 00:10:59,690 will be the next. 111 00:10:59,710 --> 00:11:07,210 So here, registration, no registration number. 112 00:11:08,110 --> 00:11:13,300 And here, registration number is variable name. 113 00:11:13,930 --> 00:11:16,330 OK, now cubic capacity. 114 00:11:17,740 --> 00:11:24,930 So, yeah, cubic capacity here. 115 00:11:27,700 --> 00:11:33,610 Cubic capacity and plus double quotes and cesium. 116 00:11:34,510 --> 00:11:39,600 Now let's bring out power and horsepower in the same line. 117 00:11:39,850 --> 00:11:43,270 So here power. 118 00:11:48,170 --> 00:11:53,330 Power plus kilowatt. 119 00:11:54,620 --> 00:12:00,890 And they left parentheses here, plus the horsepower. 120 00:12:02,210 --> 00:12:14,600 Plus, double quotes and HP and they write parentheses like CO2 emission is the next, so violating 121 00:12:14,600 --> 00:12:25,370 this part here CO2 emission and leaving this part of the code. 122 00:12:27,370 --> 00:12:44,460 IBM's CO2 emission plus an eye is mission missing from the air and space and gram per kilometer. 123 00:12:44,890 --> 00:12:49,750 Now the emissions sticker and the energy efficiency category. 124 00:12:50,170 --> 00:12:56,950 So doubling this line here again and here and mission. 125 00:13:00,870 --> 00:13:01,260 Take. 126 00:13:04,690 --> 00:13:15,460 Emissions sticker and hair left Prentice's energy efficiency 127 00:13:17,170 --> 00:13:18,070 category. 128 00:13:21,080 --> 00:13:22,310 Lower case. 129 00:13:23,350 --> 00:13:23,950 Colin. 130 00:13:25,670 --> 00:13:34,970 And plus, an energy efficiency category, close and double quotes and right parentheses also, let's 131 00:13:34,970 --> 00:13:38,090 add a space here, too, and that's it. 132 00:13:39,510 --> 00:13:42,760 OK, now let's move on to the next line here. 133 00:13:43,170 --> 00:13:50,910 So the fuel consumption, so doubling this line and here. 134 00:13:52,540 --> 00:13:59,500 Combined fuel consumption. 135 00:14:01,120 --> 00:14:03,100 Colin Plus. 136 00:14:04,260 --> 00:14:12,330 Here, fuel consumption combined and the leaf in this part of the code. 137 00:14:13,960 --> 00:14:21,610 And here later, per 100 kilometers, the next three is going to be easy. 138 00:14:21,640 --> 00:14:31,840 So just simply doubling this line and instead of combined, we're going to use urban world and changing 139 00:14:31,840 --> 00:14:35,140 the variable name here to urban. 140 00:14:36,280 --> 00:14:39,850 Doubling this line, yeah, extra urban. 141 00:14:41,770 --> 00:14:44,260 And the text as well. 142 00:14:45,390 --> 00:14:45,640 Here, 143 00:14:48,610 --> 00:14:49,570 one more left. 144 00:14:54,160 --> 00:14:55,180 Pressors. 145 00:14:57,730 --> 00:15:02,170 Average fuel consumption here changing this. 146 00:15:04,210 --> 00:15:11,710 Precise average, so three more variables left to go, number of previous owners, number of those and 147 00:15:11,710 --> 00:15:12,640 a number of seats. 148 00:15:13,270 --> 00:15:14,590 So here. 149 00:15:15,570 --> 00:15:17,580 Bubbling face again. 150 00:15:19,650 --> 00:15:21,180 Anything this. 151 00:15:22,560 --> 00:15:24,370 Number of. 152 00:15:25,780 --> 00:15:28,810 Previous oh, those. 153 00:15:29,950 --> 00:15:35,890 And here, number of vehicle owners. 154 00:15:37,970 --> 00:15:41,210 Doubling this line number of. 155 00:15:43,910 --> 00:15:44,630 Those. 156 00:15:50,940 --> 00:15:57,120 And finally, number of seats. 157 00:16:00,610 --> 00:16:02,560 OK, so now we're done. 158 00:16:02,920 --> 00:16:08,560 Let's go to the Green Arrow up here and select Ron. 159 00:16:10,400 --> 00:16:16,430 So now you can see all the variables and the text we just tied in as an output here. 160 00:16:18,010 --> 00:16:19,460 I know it was a bit long. 161 00:16:19,810 --> 00:16:22,600 Feel free to pause the video and take a break. 162 00:16:22,600 --> 00:16:27,090 In the next lecture, I will show you how to convert a death type into another one. 163 00:16:27,840 --> 00:16:28,690 Save the.
