1 00:00:00,910 --> 00:00:07,270 Hello and welcome to this annual lesson in which we are going to discuss main components of any floor 2 00:00:07,270 --> 00:00:10,590 charting now. 3 00:00:10,820 --> 00:00:16,310 As you can see we are drawing a floor chart you are using symbols. 4 00:00:16,310 --> 00:00:22,640 These are symbols that are widely known among programmers. 5 00:00:22,760 --> 00:00:29,430 So they are like stand ups and you have to know what each of these symbols mean. 6 00:00:29,450 --> 00:00:40,240 List south by this symbol this symbol is a floor line as you can see it's an arrow that has a direction 7 00:00:40,240 --> 00:00:41,530 from left to right. 8 00:00:41,530 --> 00:00:50,750 So this is the direction of flow a flow line is used to connect symbols and indicate the flow of logic 9 00:00:52,760 --> 00:00:55,290 while the second symbol is a terminal. 10 00:00:55,340 --> 00:00:58,820 As you can see this is a terminal. 11 00:00:58,820 --> 00:01:08,210 It's used to represent the beginning or soft and or the end of a task. 12 00:01:08,210 --> 00:01:15,860 So at the beginning of a task and at the end of that task you have to add this element and usually you 13 00:01:15,860 --> 00:01:17,120 will use them to solve. 14 00:01:17,120 --> 00:01:24,860 And in these tasks to indicate the start and end of these tasks we are going to see this in examples 15 00:01:25,270 --> 00:01:32,640 in the next section this symbol is used for input and output. 16 00:01:32,890 --> 00:01:40,910 It's mainly used for input and output operations such as reading and displaying values that are to be 17 00:01:40,910 --> 00:01:45,650 read or displayed are described inside this symbol. 18 00:01:45,710 --> 00:01:55,270 We are all going to write things here inside it to describe the data that we are going to read or simply. 19 00:01:55,470 --> 00:01:59,010 Now this is a processing symbol. 20 00:01:59,010 --> 00:02:01,980 It's one of the most commonly used symbols. 21 00:02:02,340 --> 00:02:13,590 It's used for any logic or comparison operations unlike the input output and processing symbols which 22 00:02:13,590 --> 00:02:25,980 have one in three and one exit this symbol is used for arithmetic and data manipulation operations. 23 00:02:25,980 --> 00:02:28,860 The instructions are listed inside this symbol. 24 00:02:28,860 --> 00:02:38,940 So if we are going to make a lot of mythical creation 1 let's say I equals one plus one 25 00:02:41,850 --> 00:02:45,910 this is an operation that can be done inside this symbol it's a rectangle. 26 00:02:46,080 --> 00:02:52,320 While this symbol is used to input and output so form to display a value we can write the Sibley 27 00:02:57,730 --> 00:03:00,860 let's say x x is a variable here. 28 00:03:00,880 --> 00:03:08,320 Now do the fourth or let's say the fifth symbol which which is that position symbol. 29 00:03:08,560 --> 00:03:17,380 It's used for any logic or comparison operations unlike the input output and processing symbols which 30 00:03:17,380 --> 00:03:25,890 have one in three and one exit flow line that decision symbol has one in three and two Exit Passes. 31 00:03:25,900 --> 00:03:30,130 So this terminal has one input and an output. 32 00:03:30,160 --> 00:03:41,610 This one also has one input and one output while this one has one input and two outputs. 33 00:03:41,740 --> 00:03:52,590 This is because this is a decision symbol so it will be either yes or through formal or false. 34 00:03:52,630 --> 00:03:59,530 So if the answer to this question that we are asking side this symbol is like if statement it is yes 35 00:03:59,650 --> 00:04:00,610 it will go here. 36 00:04:00,820 --> 00:04:02,200 If it's no it will go ahead. 37 00:04:03,470 --> 00:04:05,290 That's very simple and straightforward. 38 00:04:06,780 --> 00:04:12,910 Now these are the most commonly used symbols in floor charting. 39 00:04:13,000 --> 00:04:21,200 Now we want to make an example for that decision let's say x above 5. 40 00:04:21,500 --> 00:04:29,660 If yes it will go and execute something if no two will go and let's celebrate the process of input output 41 00:04:30,890 --> 00:04:38,230 and can go here we are going to have to explain this in a practical examples in the next section. 42 00:04:38,230 --> 00:04:40,720 But for now this is all what you need to do. 43 00:04:40,720 --> 00:04:43,360 This is the flow line indicating the flow of logic. 44 00:04:43,360 --> 00:04:45,820 This is false start and end of the task. 45 00:04:45,850 --> 00:04:48,640 This is to take inputs and simply outputs. 46 00:04:48,640 --> 00:04:53,630 This is for processing and this is for decision making. 47 00:04:53,710 --> 00:04:58,030 Let's move on to the next symbols. 48 00:04:58,030 --> 00:05:05,620 This circular symbol is a connector a connector is used to join different flow lines. 49 00:05:05,620 --> 00:05:14,050 So if we have four lines coming here and a flow line coming here along coming here we can join them 50 00:05:14,050 --> 00:05:21,200 using this connector symbol the next symbol is an off page connector. 51 00:05:21,490 --> 00:05:31,150 This symbol can be used when you have a very low flow chart and you are out of room in your page and 52 00:05:31,150 --> 00:05:37,660 you have to continue another page you must endure a first page flow line with this symbol. 53 00:05:37,660 --> 00:05:45,550 So it's used to indicate that the flow chart continues to a second page. 54 00:05:45,560 --> 00:05:50,840 Now let's move on to the predefined process symbol. 55 00:05:50,840 --> 00:05:59,480 As you can see it's a rectangle with two lines here and here it's used to represent a group of statements 56 00:05:59,510 --> 00:06:02,630 that perform one processing task. 57 00:06:02,720 --> 00:06:06,980 So it's like functions and programming. 58 00:06:06,980 --> 00:06:13,220 You can add multiple statement inside it and you can call them using this symbol predefined process 59 00:06:14,650 --> 00:06:22,240 the last symbol is annotation as you can see this symbol is used to provide additional information about 60 00:06:22,300 --> 00:06:24,480 another flowchart symbol. 61 00:06:24,610 --> 00:06:34,400 Let's say that we are here and we added X we can add the notation symbol here and say X is the temperature 62 00:06:34,820 --> 00:06:35,540 as example 63 00:06:41,170 --> 00:06:47,980 this is how we can use annotation to add information about other flow symbol. 64 00:06:48,040 --> 00:06:56,740 These are the main components of any flow chart thing and you have to know all of them because we are 65 00:06:56,740 --> 00:06:59,890 going to use them in the practical section. 66 00:06:59,890 --> 00:07:07,630 So I prefer that you take a paper pen on paper and write them down right what each of these means so 67 00:07:07,630 --> 00:07:12,820 that you can know what we are talking about in the practical example section. 68 00:07:12,880 --> 00:07:18,300 Let's take a quick look at all of them flow line to indicate the flow of logic. 69 00:07:18,370 --> 00:07:21,620 Terminal 4 start and end of a task. 70 00:07:21,670 --> 00:07:28,270 This is for input and output to the Sibley outputs and to take inputs. 71 00:07:28,270 --> 00:07:31,930 This is for processing for athletic operations. 72 00:07:31,930 --> 00:07:40,720 This is if you have a decision such as if statement and programming this to join multiple flow lines 73 00:07:40,930 --> 00:07:46,400 this to indicate that the flow chart continues in a second page. 74 00:07:46,480 --> 00:07:56,020 This is a pre-defined process symbol to enable you to add multiple tasks in one location and call it 75 00:07:56,020 --> 00:07:58,380 would evolve or whatever you want. 76 00:07:58,390 --> 00:08:04,940 This is a notation to this would be information about another flow chart symbol. 77 00:08:05,020 --> 00:08:08,220 I hope that you understand these symbols. 78 00:08:08,230 --> 00:08:13,050 If you have any question about any of them please ask and that you aren't able. 79 00:08:13,120 --> 00:08:15,280 Thanks for watching this lesson. 80 00:08:15,280 --> 00:08:16,540 See you next. 81 00:08:16,570 --> 00:08:18,480 This is coding Academy.
