Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 00:00:00,270 --> 00:00:01,620 All right, welcome back, guys. 2 00:00:01,650 --> 00:00:03,780 So in this video, we are going through, right? 3 00:00:04,030 --> 00:00:08,820 Simple example, a simple example for a function in C programming language. 4 00:00:08,940 --> 00:00:14,970 So these functions should basically be some reading function that only does the Toli does. 5 00:00:14,970 --> 00:00:22,230 It's just a reading function, reading function that all he does is simply running some print F commands. 6 00:00:22,380 --> 00:00:23,610 And this function. 7 00:00:23,640 --> 00:00:28,840 All he does is simply to to do what's to, let's say, printing. 8 00:00:28,890 --> 00:00:29,580 Hello. 9 00:00:29,880 --> 00:00:31,830 This will be printed out on the first line. 10 00:00:32,160 --> 00:00:33,990 And the second line we will have. 11 00:00:34,290 --> 00:00:38,790 Welcome to the best course ever. 12 00:00:38,910 --> 00:00:42,690 Right ever in C programming. 13 00:00:42,750 --> 00:00:44,520 Programming language. 14 00:00:44,640 --> 00:00:46,320 This will be the second line. 15 00:00:46,710 --> 00:00:52,380 And on the third line, our function will bring something like a good luck message. 16 00:00:52,880 --> 00:00:53,280 All right. 17 00:00:53,310 --> 00:00:58,470 So all these function will do is simply to run, to execute, to print on the screen. 18 00:00:58,800 --> 00:01:02,340 These three lines of information. 19 00:01:02,600 --> 00:01:06,010 So the function is going to be with no parameters. 20 00:01:06,030 --> 00:01:07,440 It will not get. 21 00:01:07,470 --> 00:01:09,780 It will not expect to receive any parameters. 22 00:01:09,810 --> 00:01:11,580 And it will not return anything. 23 00:01:11,880 --> 00:01:15,270 It will simply be like a guy that you just call him. 24 00:01:15,390 --> 00:01:17,310 You don't pass him anything. 25 00:01:17,730 --> 00:01:22,170 And also, you do not expect to receive anything in return. 26 00:01:22,320 --> 00:01:23,490 You simply call him. 27 00:01:23,520 --> 00:01:26,280 And all he does is to print something to the screen. 28 00:01:26,280 --> 00:01:32,880 And you know that once this guy is over with his task, that, you know, its task is simply to bring 29 00:01:32,880 --> 00:01:34,350 something to your screen. 30 00:01:34,840 --> 00:01:36,990 What once he's done with these tasks. 31 00:01:37,130 --> 00:01:39,150 You can move on to the next commands. 32 00:01:39,270 --> 00:01:43,260 So let's see how our signature for this function will look like. 33 00:01:43,290 --> 00:01:43,670 All right. 34 00:01:43,680 --> 00:01:48,000 So first of all, we know that this function will not return anything. 35 00:01:48,120 --> 00:01:54,960 So the type of the function we said previously is going to be of not an integer, not a double, not 36 00:01:54,960 --> 00:01:57,840 a double, not a char or nothing like that. 37 00:01:58,020 --> 00:02:04,770 The type of the function is going to be specified as Avoid the Void says that we will not expect to 38 00:02:04,770 --> 00:02:09,420 receive anything in return are once the function has been. 39 00:02:10,350 --> 00:02:12,930 As it has ran all of its commands. 40 00:02:13,050 --> 00:02:17,280 And then we are going to to specify the function name. 41 00:02:17,280 --> 00:02:19,430 So we will go like preened. 42 00:02:19,470 --> 00:02:20,060 Let's go. 43 00:02:20,070 --> 00:02:21,270 Preened readings. 44 00:02:21,540 --> 00:02:21,770 Right. 45 00:02:21,900 --> 00:02:23,010 Print reading. 46 00:02:23,100 --> 00:02:24,280 Let's say print greetings. 47 00:02:24,290 --> 00:02:25,140 Bring greetings. 48 00:02:25,200 --> 00:02:25,620 All right. 49 00:02:25,890 --> 00:02:27,390 So this is the functions name. 50 00:02:27,420 --> 00:02:28,080 This is what. 51 00:02:28,350 --> 00:02:29,100 The function. 52 00:02:29,360 --> 00:02:29,900 The function. 53 00:02:29,900 --> 00:02:31,800 Stipe and this is the function name. 54 00:02:31,950 --> 00:02:36,710 And now we know that the function will not expect to get any parameters. 55 00:02:36,780 --> 00:02:40,740 So we'll just use empty parentheses here. 56 00:02:40,980 --> 00:02:43,860 And we will not specify anything in this. 57 00:02:43,930 --> 00:02:46,410 Are borage so far or signature? 58 00:02:46,560 --> 00:02:52,140 So now what we've created is a simple function that for now it does not has anything. 59 00:02:52,140 --> 00:02:53,480 It does not contain anything. 60 00:02:53,820 --> 00:02:56,310 And what we would like to do next. 61 00:02:56,340 --> 00:02:58,280 This is specified the function body. 62 00:02:58,290 --> 00:03:00,450 So it will go with these curly brackets. 63 00:03:00,600 --> 00:03:07,080 And now everything that is going to be between these curly brackets is going to be a part of these preening 64 00:03:07,620 --> 00:03:09,560 print greetings function. 65 00:03:09,990 --> 00:03:13,580 So we are going to specify the first print of command. 66 00:03:13,620 --> 00:03:15,420 So it's just like hello. 67 00:03:16,380 --> 00:03:17,100 And a backslash. 68 00:03:17,100 --> 00:03:23,400 And at the end, although we could just use all of these attacks to print it out in just one print of 69 00:03:23,400 --> 00:03:29,190 command by specifying that the correct places the backslash and we are going to divided the three print 70 00:03:29,190 --> 00:03:30,840 of command commands. 71 00:03:30,930 --> 00:03:34,200 So it will be just more nice for us to see. 72 00:03:34,320 --> 00:03:39,780 So for the second print F line, we are going to use Spring Springtown and we are going let's just copy 73 00:03:39,780 --> 00:03:43,400 and paste this line, going to base it here. 74 00:03:43,440 --> 00:03:45,890 So backslash n at the end, semicolon. 75 00:03:46,260 --> 00:03:47,460 And there you go. 76 00:03:47,790 --> 00:03:56,300 So now now we are going to use also the third line, which is just a print half good, large message. 77 00:03:57,400 --> 00:03:58,680 The last message. 78 00:03:58,710 --> 00:04:00,240 And that's it. 79 00:04:00,440 --> 00:04:01,970 This should be like this. 80 00:04:02,090 --> 00:04:03,220 It looks nice, right? 81 00:04:03,650 --> 00:04:08,400 And now what I want us to do is to understand what we can see here. 82 00:04:08,430 --> 00:04:14,400 So once again, what we've done right now, we didn't run these function. 83 00:04:14,490 --> 00:04:17,250 We just created a template of a function. 84 00:04:17,310 --> 00:04:19,110 We just created the function itself. 85 00:04:19,380 --> 00:04:20,620 It's not being run. 86 00:04:20,970 --> 00:04:27,810 If we just if if we even build and run this program right now, these messages are not going to be seen 87 00:04:27,810 --> 00:04:28,590 on your screen. 88 00:04:29,010 --> 00:04:30,170 So you may even try it. 89 00:04:30,210 --> 00:04:30,990 Let's do it. 90 00:04:31,050 --> 00:04:31,560 Let's go. 91 00:04:31,560 --> 00:04:33,370 Like we're running it. 92 00:04:33,390 --> 00:04:36,510 And you can see that nothing nothing happens, right? 93 00:04:36,720 --> 00:04:38,180 Because we run the INS. 94 00:04:38,190 --> 00:04:38,440 Me. 95 00:04:38,520 --> 00:04:39,720 This is the entry point. 96 00:04:40,020 --> 00:04:42,270 We run this command, return zero. 97 00:04:42,420 --> 00:04:46,380 We actually do not do anything here in this main function. 98 00:04:46,660 --> 00:04:47,550 And that's it. 99 00:04:48,000 --> 00:04:50,310 So we simply created some guy. 100 00:04:50,340 --> 00:04:57,750 Let's say that he his name is print greetings and he does not expect to receive anything. 101 00:04:57,780 --> 00:04:59,370 No parameter is specified. 102 00:05:00,060 --> 00:05:04,560 And we will call him, we will not expect that he will return something. 103 00:05:04,770 --> 00:05:11,050 But all he all he does is simply to run these three print F comments, to print some information to 104 00:05:11,050 --> 00:05:11,580 the screen. 105 00:05:11,800 --> 00:05:13,590 And what interests us here. 106 00:05:13,650 --> 00:05:14,010 Right. 107 00:05:14,080 --> 00:05:15,810 We we created this function. 108 00:05:15,840 --> 00:05:17,910 We want to call this function. 109 00:05:17,910 --> 00:05:20,520 Want to rohn's these functions somehow. 110 00:05:20,640 --> 00:05:28,170 So for that, we're going to come back here at the end main function and we know that we can call every 111 00:05:28,170 --> 00:05:29,670 function by its name. 112 00:05:29,670 --> 00:05:30,020 Right. 113 00:05:30,030 --> 00:05:31,260 And the name is print. 114 00:05:31,310 --> 00:05:31,890 Greetings. 115 00:05:31,920 --> 00:05:34,620 So let's try to write down print. 116 00:05:35,280 --> 00:05:36,210 Greetings. 117 00:05:36,240 --> 00:05:37,740 Print greetings. 118 00:05:38,300 --> 00:05:39,030 Write print. 119 00:05:39,060 --> 00:05:39,750 Greetings. 120 00:05:40,440 --> 00:05:45,450 And we specify VMT parenthesis here and just semicolon at the end. 121 00:05:45,540 --> 00:05:47,960 So let's see what happens in this kit. 122 00:05:48,050 --> 00:05:50,910 In this case, let's build and run it. 123 00:05:51,080 --> 00:05:51,390 Oh. 124 00:05:51,420 --> 00:05:52,020 And there you go. 125 00:05:52,030 --> 00:05:55,290 You can see that all of the message was printed on the screen. 126 00:05:55,290 --> 00:05:58,630 The Hello, the welcome to the best chorusing C programming language. 127 00:05:59,040 --> 00:06:00,270 And a good luck message. 128 00:06:00,390 --> 00:06:04,350 So basically all the information of these function was printed out. 129 00:06:04,890 --> 00:06:06,780 So let's see what happened here. 130 00:06:06,810 --> 00:06:09,660 We, first of all, came to the entry point to the main. 131 00:06:10,300 --> 00:06:14,190 Then we started to execute the there these function body. 132 00:06:14,190 --> 00:06:14,450 Right. 133 00:06:14,460 --> 00:06:17,250 The first command and then the second and the third one and so on. 134 00:06:17,550 --> 00:06:25,320 So when we when we saw these print greetings, we know that you can see it in the red, that once you 135 00:06:25,320 --> 00:06:29,410 write the functions name, you are going to execute this function. 136 00:06:29,430 --> 00:06:33,120 We know that the function does not expect to receive any parameters. 137 00:06:33,180 --> 00:06:37,120 So we do not send to these function any arguments. 138 00:06:37,140 --> 00:06:37,350 Right. 139 00:06:37,370 --> 00:06:42,900 You send arguments and the function receive it as the parameters and also the function does not return 140 00:06:42,900 --> 00:06:43,350 anything. 141 00:06:43,590 --> 00:06:45,360 So we just called the function. 142 00:06:45,360 --> 00:06:50,250 We say, hey, print greetings guy, do your job and print everything to the screen. 143 00:06:50,610 --> 00:06:51,600 And there you go. 144 00:06:51,630 --> 00:06:54,660 So this is this command is the first one to be executed. 145 00:06:54,960 --> 00:06:56,550 And then you go like this. 146 00:06:56,550 --> 00:06:57,620 You print these line. 147 00:06:57,940 --> 00:06:58,700 Then this line. 148 00:06:58,740 --> 00:06:59,490 Then this line. 149 00:06:59,790 --> 00:07:03,930 Then you come for the next to the last line in this function. 150 00:07:04,410 --> 00:07:12,270 And once the function is done, running all of its commands, you are going to come back here, here, 151 00:07:12,690 --> 00:07:16,500 and you are going to proceed with this function. 152 00:07:16,680 --> 00:07:17,070 All right. 153 00:07:17,100 --> 00:07:20,580 Within my next line with line number 19. 154 00:07:20,670 --> 00:07:26,970 And very you go you basically will the return zero in your program is overeats complete. 155 00:07:27,060 --> 00:07:33,660 So I hope this makes sounds how you create a function function of type void that does not supposed to 156 00:07:33,660 --> 00:07:34,860 return anything. 157 00:07:35,010 --> 00:07:36,050 No parameters. 158 00:07:36,210 --> 00:07:40,560 You call this function here and basically let's listen and see. 159 00:07:40,560 --> 00:07:41,860 Let's add another align. 160 00:07:41,880 --> 00:07:44,280 Let's say pretend to have an. 161 00:07:44,550 --> 00:07:45,420 Hello. 162 00:07:46,950 --> 00:07:50,310 Let's say hello to this program. 163 00:07:51,470 --> 00:07:57,020 I'm writing from from main function. 164 00:07:57,380 --> 00:07:57,700 Okay. 165 00:07:57,990 --> 00:08:01,950 So this message is going to be printed out from the main function. 166 00:08:02,040 --> 00:08:07,680 And once it's printed out, we are going to call these function or print readings function. 167 00:08:08,010 --> 00:08:10,110 All of its commands are going to be executed. 168 00:08:10,350 --> 00:08:15,720 And then we are going to come back here and say, let's say just just that you will see the difference 169 00:08:15,720 --> 00:08:16,800 in how the flow goes. 170 00:08:18,240 --> 00:08:22,050 Now, I am after the function. 171 00:08:23,160 --> 00:08:24,420 Also at main. 172 00:08:24,720 --> 00:08:26,480 Also at Main. 173 00:08:26,750 --> 00:08:27,020 Okay. 174 00:08:27,660 --> 00:08:31,560 And we will add a backslash and the and the semicolon at the end. 175 00:08:31,710 --> 00:08:34,860 So now if we build and run it, let's see what happens. 176 00:08:34,950 --> 00:08:35,370 All right. 177 00:08:35,490 --> 00:08:37,440 Oh, we have the message here. 178 00:08:37,440 --> 00:08:37,680 Why. 179 00:08:37,680 --> 00:08:38,690 What is the problem? 180 00:08:38,830 --> 00:08:40,650 I got a semicolon in the end. 181 00:08:40,980 --> 00:08:42,180 Don't forget a semicolon. 182 00:08:42,330 --> 00:08:45,210 Otherwise, bad things may happen. 183 00:08:45,300 --> 00:08:46,500 So let's run it. 184 00:08:46,710 --> 00:08:47,560 And there you go. 185 00:08:47,580 --> 00:08:52,140 You can see that the first message is hello, this hello to this program. 186 00:08:52,140 --> 00:08:53,940 I'm writing from main function. 187 00:08:54,300 --> 00:08:59,730 And once in these messages printed out all the functional body of the print. 188 00:08:59,760 --> 00:09:00,230 Greetings. 189 00:09:00,760 --> 00:09:02,950 I am of the print greetings. 190 00:09:03,420 --> 00:09:05,190 Function is being executed. 191 00:09:05,580 --> 00:09:09,410 And then we have it was like one, two and good luck. 192 00:09:09,510 --> 00:09:11,910 Oh, I didn't specify backslash and at this function. 193 00:09:12,210 --> 00:09:13,260 Let me see. 194 00:09:13,270 --> 00:09:13,940 Let me check out. 195 00:09:14,670 --> 00:09:15,390 There you go. 196 00:09:15,420 --> 00:09:20,790 You should also specify because Lashan and once these functions is over, we are going to proceed with 197 00:09:20,790 --> 00:09:24,330 this line after all of these lines were printed out on the screen. 198 00:09:24,400 --> 00:09:27,810 Who so this this was not so easy. 199 00:09:27,840 --> 00:09:33,450 But I think you've got the idea we create a function and then we can call this function. 200 00:09:33,600 --> 00:09:36,510 So this is it, for example, number one. 201 00:09:36,780 --> 00:09:40,050 And let us proceed with the second example. 16032
