WEBVTT 00:00.680 --> 00:05.800 Now let's get started with manipulating several elements in our array here. 00:05.810 --> 00:09.440 So in order to manipulate it, we need to get an index number. 00:09.440 --> 00:15.740 So array two here in this case, array two, the second index is eight seven. 00:16.130 --> 00:22.130 As you can see here, we will make the index of 2 to 50 here. 00:22.340 --> 00:26.300 And also we will also make the. 00:27.180 --> 00:28.950 We will also see that the third array. 00:29.310 --> 00:30.720 So my array. 00:31.530 --> 00:33.270 Uh, the third. 00:33.660 --> 00:35.070 And here, let's make it. 00:37.470 --> 00:38.100 70? 00:38.140 --> 00:38.360 Yes. 00:38.430 --> 00:40.410 75 or 73. 00:42.130 --> 00:43.450 And now. 00:44.380 --> 00:50.800 What we will doing here is that we are deleting here. 00:53.480 --> 01:00.620 And actually after that, let's actually create our code again, write it like that here, see out the 01:00.620 --> 01:02.060 new array elements. 01:03.230 --> 01:05.480 New array elements. 01:05.510 --> 01:06.590 Elements here. 01:06.590 --> 01:08.570 And it's going to be the. 01:09.240 --> 01:10.530 And line. 01:11.280 --> 01:14.280 And we will do we will write the same code. 01:14.310 --> 01:15.330 Again here. 01:15.330 --> 01:19.950 So we will compare this, uh, this race here. 01:19.950 --> 01:21.660 So we will compare. 01:22.290 --> 01:26.850 Uh, the result and output differences between these codes. 01:26.850 --> 01:28.260 So, uh, after manipulating. 01:28.290 --> 01:30.990 Of course, here, after manipulating our code. 01:31.380 --> 01:34.020 So now we're going to here. 01:39.830 --> 01:41.120 So now we're going to. 01:43.790 --> 01:45.170 Paste this code here again. 01:45.170 --> 01:47.810 So these are this is the same output. 01:49.790 --> 01:50.360 Here. 01:50.480 --> 01:51.890 This is the same output. 01:52.130 --> 01:57.070 And here, actually, before running, let's actually let me explain this. 01:57.080 --> 02:04.520 So this code we see that initializing an array is simple and this is the dome by defining the array 02:04.520 --> 02:05.210 data type. 02:05.210 --> 02:09.440 So the arrays name here, race name. 02:10.300 --> 02:11.050 Follow it. 02:12.310 --> 02:16.610 By a couple of score bracelets here. 02:16.630 --> 02:23.240 And as you can see here in this case, it's this the couple of square braces here. 02:23.260 --> 02:26.350 So let's actually let me write it again. 02:26.350 --> 02:33.550 And as you can see here, uh, initializing array is simple and defining the array type is more simpler 02:33.550 --> 02:33.970 here. 02:33.970 --> 02:40.480 So we need in order to access these arrays, we just need to use the array types here. 02:40.810 --> 02:49.630 Let me actually use the width narrower here and a bit narrower to here, so. 02:50.750 --> 02:51.530 So. 02:52.380 --> 02:53.250 In this code. 02:53.280 --> 02:58.050 Our array name is my array that we created here. 02:58.080 --> 02:59.160 My array. 03:00.220 --> 03:09.250 So we can access each element by using its index here, the three, two and etcetera. 03:10.670 --> 03:16.430 So in the code we print each element by iterating. 03:17.970 --> 03:25.950 By iterating and accessing the element value using the array and E here. 03:25.950 --> 03:28.020 So E is incrementing. 03:28.020 --> 03:36.300 So it starts from zero and the second loop goes one, two, three, four. 03:36.300 --> 03:45.240 And after being e being four, we are checking that the size of array is no size of E is no longer less 03:45.240 --> 03:47.840 than our array size. 03:47.850 --> 03:51.210 Then after that we are breaking the loop. 03:51.210 --> 03:57.990 So you learned about loops in previous lectures, so I will not return to the loops again. 03:58.860 --> 04:06.060 But if you don't remember the loops well you can check the previous lectures here and then come again 04:06.060 --> 04:06.720 here. 04:07.770 --> 04:12.270 So let's continue our array here. 04:15.230 --> 04:18.320 So actually, let's delete this using the rubber. 04:19.320 --> 04:21.900 Here now. 04:24.450 --> 04:31.440 Uh, we also manipulate the value of indexes the two and three by using. 04:31.440 --> 04:32.130 Actually, it's. 04:32.190 --> 04:40.230 Yeah, we are manipulating the value of indexes by using the two and three here, as you can see here. 04:40.350 --> 04:44.820 So we are assigning 2 to 50. 04:44.820 --> 04:52.050 So the second index, second index goes to 50 here and actually see that. 04:52.080 --> 04:54.030 So second index here. 04:54.120 --> 04:56.670 The second thing, what's the second index here? 04:56.700 --> 04:57.600 87. 04:57.600 --> 05:02.250 So 87 the index to new value is going to be. 05:03.780 --> 05:04.290 What? 05:04.290 --> 05:05.940 The 50 here? 05:05.940 --> 05:06.630 50. 05:08.360 --> 05:10.680 The new value is 50. 05:10.700 --> 05:14.420 And also we are assigning index 3 to 7. 05:14.450 --> 05:16.480 Actually, it's not like that. 05:16.490 --> 05:24.010 It's it's like here we are assigning 50 to index two, we are assigning 73 to index three. 05:24.020 --> 05:27.470 So in this case it's going to be the index. 05:27.470 --> 05:28.250 Two is going to be. 05:30.060 --> 05:30.840 Here. 05:31.440 --> 05:33.870 Index two is going to be 50. 05:34.590 --> 05:36.690 So this is the new value index. 05:36.690 --> 05:42.660 Two is going to be 50 and index three is going to be. 05:43.750 --> 05:51.340 73 here and index three is going to be 73. 05:52.450 --> 05:54.760 73. 05:56.970 --> 05:57.660 Here. 05:58.530 --> 06:03.750 So, uh, the if a build and run this application, let's, uh. 06:03.750 --> 06:08.670 So this was our previous compilation and the result. 06:09.360 --> 06:10.740 Let's use the earth. 06:10.770 --> 06:12.030 All of this here. 06:14.630 --> 06:17.990 And here, let's run it again. 06:18.470 --> 06:21.230 Compile it again and run it again here. 06:21.230 --> 06:22.940 And as you can see here. 06:23.680 --> 06:25.720 The first element goes like this. 06:25.930 --> 06:26.740 25. 06:26.770 --> 06:27.700 21. 06:27.730 --> 06:28.210 Yes. 06:28.240 --> 06:28.870 Is 21. 06:28.870 --> 06:30.820 We didn't do anything to 21. 06:30.850 --> 06:34.960 The first zero index we have the. 06:36.260 --> 06:41.270 Actually, yeah, we have this 47 and as you can see, it goes the usual. 06:41.300 --> 06:51.950 The was the same with the 21, 20 and 47, 21, 47 And here we also have 87. 06:52.160 --> 06:53.720 This was the previous ones here. 06:53.720 --> 06:55.610 So these are all the same. 06:58.390 --> 06:59.470 This is all the same. 06:59.470 --> 07:05.140 And as you can see here, after that, 87 here is changing. 07:05.410 --> 07:09.670 We are manipulating, uh, the index, uh, the value of our array. 07:09.670 --> 07:12.820 And as you can see, it is seven goes the. 07:14.610 --> 07:15.720 250. 07:15.750 --> 07:19.410 And as you can see here, the new value is 50. 07:20.460 --> 07:21.300 So we don't need that. 07:21.510 --> 07:28.770 And the 6969 here changed its value to 73. 07:28.770 --> 07:32.310 And as you can see here, it's 50 and 73. 07:32.310 --> 07:38.790 And about the 35 here, it's the same again. 07:38.880 --> 07:41.760 So there's an interesting fact about arrays here. 07:41.760 --> 07:45.180 So we can access the arrays element using a pointer. 07:45.180 --> 07:51.210 So as you may know, a pointer is a variable that holds the address instead of the value. 07:52.000 --> 07:52.630 So. 07:52.630 --> 07:59.590 And since we have, uh, learned earlier that each element in array has its own address, as you can 07:59.590 --> 08:00.550 see here. 08:01.450 --> 08:05.500 Uh, we can access each element, each arrays element using its address. 08:05.650 --> 08:10.510 So we can also use the pointer to, uh, as an array. 08:10.510 --> 08:15.280 So we'll, you will learn this in next lecture. 08:15.280 --> 08:15.990 So I'm waiting you in. 08:16.010 --> 08:16.510 Next lecture.
