1 00:00:01,220 --> 00:00:02,750 Hey, guys, what's up? 2 00:00:03,320 --> 00:00:07,500 So today was all one more interesting problem with the help of for loop. 3 00:00:08,600 --> 00:00:10,700 OK, so the problem treatment is very easy. 4 00:00:11,000 --> 00:00:14,990 We have to find it or the power be, but without using power function. 5 00:00:15,350 --> 00:00:16,880 So this is power function. 6 00:00:17,500 --> 00:00:17,700 OK. 7 00:00:18,260 --> 00:00:21,260 So we will not do this power function with the help of for loop. 8 00:00:21,560 --> 00:00:22,480 We have to find it. 9 00:00:22,550 --> 00:00:23,950 The power be OK. 10 00:00:24,290 --> 00:00:25,310 So we all know it. 11 00:00:25,340 --> 00:00:27,740 The power B is the same as E. 12 00:00:27,780 --> 00:00:28,790 Multiply A. 13 00:00:28,850 --> 00:00:29,810 Multiply A. 14 00:00:29,870 --> 00:00:31,730 Multiply A how many times. 15 00:00:31,940 --> 00:00:32,660 B times. 16 00:00:34,030 --> 00:00:34,260 OK. 17 00:00:34,520 --> 00:00:37,310 For example, if you want to calculate to do the power five. 18 00:00:37,430 --> 00:00:38,150 What do you do. 19 00:00:38,620 --> 00:00:41,420 Do do do do do do do. 20 00:00:41,450 --> 00:00:43,880 In total that is thirty two. 21 00:00:44,270 --> 00:00:44,480 OK. 22 00:00:44,750 --> 00:00:47,210 So eight of the power B is something like this. 23 00:00:48,020 --> 00:00:48,890 So what do we do. 24 00:00:49,130 --> 00:00:54,090 We will run a loop with time and we will run a loop B times and each time what I will do. 25 00:00:54,110 --> 00:00:55,490 I will take a variable answer. 26 00:00:55,850 --> 00:00:57,620 So answer equals answer. 27 00:00:57,740 --> 00:00:58,430 Multiply. 28 00:00:59,930 --> 00:01:00,180 OK. 29 00:01:00,410 --> 00:01:02,150 So this we have to do. 30 00:01:02,750 --> 00:01:06,830 I will take a variable answer and answer it cause I say multiply by a. 31 00:01:07,370 --> 00:01:10,790 So just like some we have initialized the same equals zero. 32 00:01:11,030 --> 00:01:13,660 So here I will initialize my answer to one. 33 00:01:14,210 --> 00:01:16,160 Otherwise my output will be wrong. 34 00:01:16,340 --> 00:01:16,570 OK. 35 00:01:16,640 --> 00:01:18,680 So we have to initialize answer equals one. 36 00:01:19,040 --> 00:01:21,920 Just like we have initialized some equals zero. 37 00:01:22,590 --> 00:01:22,760 OK. 38 00:01:23,240 --> 00:01:23,920 So let's see. 39 00:01:26,130 --> 00:01:28,470 So I'm naming this file as forward. 40 00:01:29,840 --> 00:01:35,990 So far, dard cpv father dard cbb. 41 00:01:53,010 --> 00:01:55,470 OK, so let's stick to the Moataz input. 42 00:01:56,010 --> 00:01:57,660 So and A and B, other two numbers. 43 00:01:57,900 --> 00:02:00,710 He was able to give us the value of A and B.. 44 00:02:01,940 --> 00:02:02,160 OK. 45 00:02:02,580 --> 00:02:04,680 So we have something called power function. 46 00:02:05,010 --> 00:02:10,770 So A C out, B or W and buildable will take two numbers. 47 00:02:11,010 --> 00:02:12,780 E to the power B. 48 00:02:16,440 --> 00:02:17,570 OK, so. 49 00:02:22,490 --> 00:02:25,430 So this power function is an event function. 50 00:02:25,520 --> 00:02:31,260 It will take two numbers as input and it will give me our protest to the power of the power. 51 00:02:32,290 --> 00:02:32,570 OK. 52 00:02:33,050 --> 00:02:34,580 So this is inbuilt function. 53 00:02:36,840 --> 00:02:39,040 Now, this function has been defined. 54 00:02:39,460 --> 00:02:47,440 This function is defined in a high-Profile call, C met just like seen in C out are defined in this 55 00:02:47,440 --> 00:02:47,830 file. 56 00:02:48,610 --> 00:02:50,770 So a scene in C are defined in this way. 57 00:02:50,860 --> 00:02:52,240 So we included this file. 58 00:02:53,650 --> 00:02:57,040 So similarly, power is defined in a file called C Met. 59 00:02:57,070 --> 00:03:00,730 The functionality of power function is written in a file called See Met. 60 00:03:01,090 --> 00:03:06,820 So if we want to use Buhr W function power function in our code, we have to include this file. 61 00:03:07,450 --> 00:03:08,750 So let us include this file. 62 00:03:09,470 --> 00:03:11,410 But the vice compiler will show us at it. 63 00:03:11,830 --> 00:03:16,510 So let's see the compiler showing me error that he don't know what dispute W. 64 00:03:17,600 --> 00:03:21,610 So let us include the C math file. 65 00:03:21,680 --> 00:03:24,380 So include C Matt. 66 00:03:31,380 --> 00:03:33,140 Now, the compiler is not being error. 67 00:03:33,560 --> 00:03:37,040 For example, I want to find proof of the power faith allowed for this study. 68 00:03:37,820 --> 00:03:38,090 OK. 69 00:03:38,570 --> 00:03:41,690 So now let us do the same thing with the help of for loop. 70 00:03:42,050 --> 00:03:45,050 So initially, my answer will be one by one. 71 00:03:45,320 --> 00:03:50,660 If you log initialize as I will contain garbage, will you and your output will be wrong. 72 00:03:51,380 --> 00:03:53,960 So four and I equals one. 73 00:03:53,990 --> 00:03:57,290 How many times I have to run this loop, I have to run this loop b times. 74 00:03:58,880 --> 00:04:02,930 And what I will do, I will do answer equals answer. 75 00:04:03,110 --> 00:04:05,240 Multiply by E. 76 00:04:06,090 --> 00:04:06,380 OK. 77 00:04:07,040 --> 00:04:09,980 And finally I will see. 78 00:04:09,980 --> 00:04:12,500 I would answer. 79 00:04:13,130 --> 00:04:17,000 So this is all that we have to do to solve this easy problem. 80 00:04:17,920 --> 00:04:21,290 Now let's see whether our logic is correct or not. 81 00:04:23,680 --> 00:04:28,700 So I want to find the power five, so it had to do and I do to. 82 00:04:29,380 --> 00:04:32,740 So this 3DO is given by this board function. 83 00:04:32,770 --> 00:04:35,190 The second thing, too, is our answer. 84 00:04:36,850 --> 00:04:37,600 One more time. 85 00:04:39,990 --> 00:04:41,400 So I want to find. 86 00:04:42,730 --> 00:04:44,060 Tale to the power it. 87 00:04:46,610 --> 00:04:49,070 So my answer is correct. 88 00:04:49,190 --> 00:04:49,490 OK. 89 00:04:50,180 --> 00:04:51,870 So a court is correct. 90 00:04:52,460 --> 00:04:57,340 If you want to implement this question with the help of via loop, what do you do? 91 00:04:58,160 --> 00:04:58,940 You will write. 92 00:05:01,030 --> 00:05:03,770 First you racialize and I equals one. 93 00:05:04,530 --> 00:05:09,570 Then you will write the condition while I is less than articles to be. 94 00:05:10,560 --> 00:05:12,030 Then you will write. 95 00:05:12,150 --> 00:05:12,630 I'm sorry. 96 00:05:12,760 --> 00:05:17,940 Was answer multiply by a and then you will write I. 97 00:05:18,120 --> 00:05:19,230 Plus plus. 98 00:05:20,010 --> 00:05:21,690 So this is my initialization. 99 00:05:22,170 --> 00:05:23,850 This is my initialization. 100 00:05:24,720 --> 00:05:26,040 This is my condition. 101 00:05:26,220 --> 00:05:27,510 This is my condition. 102 00:05:28,020 --> 00:05:28,930 This is updated. 103 00:05:29,130 --> 00:05:30,840 And similarly, this is update. 104 00:05:31,990 --> 00:05:32,220 OK. 105 00:05:32,850 --> 00:05:38,160 So again, the principle behind the for loop and the way I look working is exactly same. 106 00:05:39,680 --> 00:05:42,860 So if you have any doubt in this question, you can ask me. 107 00:05:43,130 --> 00:05:43,360 OK. 108 00:05:43,790 --> 00:05:44,940 So inside see malfunction. 109 00:05:45,110 --> 00:05:53,000 We also have many functions like see out a security squirty means find these squirrelled. 110 00:05:53,090 --> 00:05:59,130 For example, I want to find this greater Delfi and Lexia, Brent and Lahn also. 111 00:05:59,480 --> 00:06:01,800 So I want to find us greater Duffy Eskew. 112 00:06:01,800 --> 00:06:03,710 Our dysfunction will give me the square root of it. 113 00:06:03,800 --> 00:06:06,350 And it is also defined in our defined called See Matt. 114 00:06:10,600 --> 00:06:13,040 So let's say the value of it is nine. 115 00:06:13,570 --> 00:06:16,900 And I want to find and let's say the value of B is for. 116 00:06:19,700 --> 00:06:20,630 Okay, so. 117 00:06:24,530 --> 00:06:26,330 So squared off, nine is three. 118 00:06:26,420 --> 00:06:28,160 And this is nine to the power for. 119 00:06:30,490 --> 00:06:31,030 OK, guys. 120 00:06:31,330 --> 00:06:32,880 So this is it for this video. 121 00:06:32,920 --> 00:06:34,660 If you have any doubt, feel free to ask. 122 00:06:34,750 --> 00:06:35,400 Thank you.
