1 00:00:00,060 --> 00:00:06,240 So now let's try to consider this example to understand more on the week to year, we will be predominantly 2 00:00:06,240 --> 00:00:13,020 focusing on local and global variable and how to analyze them, you know, variable. 3 00:00:13,650 --> 00:00:16,820 OK, so let's discuss diet, right? 4 00:00:16,830 --> 00:00:23,150 So our hardware design just consists of a simple block design that we've been using from the beginning. 5 00:00:23,160 --> 00:00:24,910 We have not modified, right? 6 00:00:24,930 --> 00:00:30,390 So we have just done the modification, and this course says that you have certain functions been added. 7 00:00:30,450 --> 00:00:34,410 OK, so we could test the global as well as local variable rate. 8 00:00:34,410 --> 00:00:38,640 So we have one global variable, which we name as a global and initialized to one. 9 00:00:39,450 --> 00:00:41,930 We have one function at 13. 10 00:00:41,940 --> 00:00:46,530 So this will take over Cuba and it will simply add 13 to its value. 11 00:00:46,850 --> 00:00:51,270 So here we have Tim, which is a local variable to act or did function. 12 00:00:51,270 --> 00:00:54,480 Similarly, we have a square, but this will take a variable. 13 00:00:54,570 --> 00:00:59,190 OK, and then will simply multiply it within globe right now here. 14 00:00:59,220 --> 00:01:04,020 Square them is the local variable for this function, right when we consider the main function. 15 00:01:04,620 --> 00:01:08,090 So mean also consist of four variable we have count. 16 00:01:08,190 --> 00:01:15,720 I add 13 odd squares, so our 13 basically store the result, which is written by this function. 17 00:01:15,810 --> 00:01:16,170 OK. 18 00:01:16,620 --> 00:01:23,220 So this basically written an intent that is the temporally similarly odd squares to the result written 19 00:01:23,220 --> 00:01:24,030 by this function. 20 00:01:24,260 --> 00:01:29,910 Right now, first we are performing twenty five nutrition and we are updating the values of count day 21 00:01:29,910 --> 00:01:34,110 and the result of this count we are feeding two at thirteen. 22 00:01:34,650 --> 00:01:35,010 OK. 23 00:01:35,130 --> 00:01:40,950 So this will basically add thirteen turistas and then it will be storing it in an audit. 24 00:01:41,190 --> 00:01:46,590 And finally, this value we are reading over here, OK, which will basically multiply it with the global 25 00:01:46,590 --> 00:01:46,980 variable. 26 00:01:46,980 --> 00:01:48,210 And that is here. 27 00:01:48,240 --> 00:01:49,830 And finally, we are printing, right? 28 00:01:49,860 --> 00:01:54,360 So if we execute this, could we do able to see it as a test event? 29 00:01:54,570 --> 00:02:00,720 Right now, we switch to a debug perspective so that we analyse an entire thing, right? 30 00:02:00,720 --> 00:02:03,900 So first you try to add every right. 31 00:02:03,900 --> 00:02:11,970 So we'll just be adding a breakpoint over here because we predominantly focus on local and global ready, 32 00:02:11,970 --> 00:02:19,050 but we will not be any losing what happened in and far look OK because we we already know how far loop 33 00:02:19,050 --> 00:02:19,500 is looking. 34 00:02:19,740 --> 00:02:21,330 So let me just double click over here. 35 00:02:21,690 --> 00:02:29,840 So here we have our breakpoint right now, ri right click on our debug folder never gets launched on 36 00:02:29,970 --> 00:02:30,620 hard right. 37 00:02:30,630 --> 00:02:35,850 So this will ask whether you want to relaunch or debug session, as well as whether we want to switch 38 00:02:35,850 --> 00:02:37,200 to or debug perspective. 39 00:02:37,200 --> 00:02:40,650 So we'll just click OK, OK, now this will. 40 00:02:41,570 --> 00:02:49,370 Take us right to if you just take the call, it will take us to the point where we have added a breakpoint, 41 00:02:49,370 --> 00:02:49,550 right? 42 00:02:49,600 --> 00:02:51,170 So here we have a beat by. 43 00:02:51,590 --> 00:02:58,310 And to this point you will see various variables which are local two and mean function, right? 44 00:02:58,640 --> 00:03:01,610 So we are inside the main function that is what we're executing. 45 00:03:01,610 --> 00:03:06,260 So all the variables which are local to a main function could be analyzed over here. 46 00:03:06,470 --> 00:03:11,000 And then variable view to you have a count, which is first local variable. 47 00:03:11,300 --> 00:03:15,530 Then we have an eye on address 13 and square. 48 00:03:15,590 --> 00:03:15,870 OK. 49 00:03:15,890 --> 00:03:23,450 And the point where we have added a big point to this point, we have the values for them as this rate. 50 00:03:23,450 --> 00:03:27,890 So since far look is entirely executed to count whether it is three. 51 00:03:28,760 --> 00:03:29,100 OK. 52 00:03:29,330 --> 00:03:31,040 And I count should be twenty five. 53 00:03:31,070 --> 00:03:31,260 Right. 54 00:03:31,280 --> 00:03:36,560 So this represent iterations and added in our square should be initialized to zero. 55 00:03:36,560 --> 00:03:40,850 And whenever we see an update that is highlighted with any look on the right. 56 00:03:40,850 --> 00:03:46,420 So we would see all the local variables are being updated at hand to all of them are highlighted with 57 00:03:46,790 --> 00:03:51,290 a local right now to go inside the function. 58 00:03:51,320 --> 00:03:55,160 Now this basically suggests since we are local, we are inside the main function. 59 00:03:55,160 --> 00:04:00,020 So all the local variables that we have an admin function are highlighted over here. 60 00:04:00,230 --> 00:04:06,860 But the variable, which are local to add 13 as well as square, had not been mentioned in very rich 61 00:04:06,860 --> 00:04:08,060 app that you could clearly see. 62 00:04:08,060 --> 00:04:11,720 We do not have any TAM or rescue temple here, right? 63 00:04:12,530 --> 00:04:15,350 So only the function in which we are. 64 00:04:16,310 --> 00:04:20,030 All the local variable will be highlighted right now. 65 00:04:20,180 --> 00:04:27,650 I pointed out I at 13 and here we have an eye 13 function, so let me just step inside this function. 66 00:04:27,680 --> 00:04:30,560 So the first option that will help is going inside. 67 00:04:30,560 --> 00:04:37,970 The function is stepping to make sure as soon as we had sipping do so, we are inside and at right vaccinés 68 00:04:37,970 --> 00:04:44,200 we are inside and at 13, you could see now all the local variables are highlighted, right? 69 00:04:44,240 --> 00:04:50,600 So you have an E who gave me to that argument that use every pass and say, given that we have this 70 00:04:50,630 --> 00:04:55,010 tip, great now since we are here, so it is not initialized yet. 71 00:04:55,400 --> 00:04:55,720 OK? 72 00:04:55,910 --> 00:05:01,670 So you could see the evaluate that is the value of a count variable after four for loop accretion companies, 73 00:05:01,670 --> 00:05:07,550 that is to be energy, OK, which has been updated and temp is yet to initialize so you can just click 74 00:05:07,550 --> 00:05:08,800 on step and do OK. 75 00:05:08,810 --> 00:05:11,690 So this will take us to the next statement. 76 00:05:11,780 --> 00:05:17,480 So E value is now zero, and since it is updated so you could see it is marked within an aluminum right, 77 00:05:17,480 --> 00:05:20,670 so you could argue one step and two. 78 00:05:20,750 --> 00:05:27,970 So this will take us to the next concert and then finally will be coming out of our activity. 79 00:05:28,040 --> 00:05:31,310 OK, so after we come out of an that you could now see? 80 00:05:32,330 --> 00:05:39,680 As we move on to the next function, OK, so I just 13 is updated to three one three and that is highlighted 81 00:05:40,090 --> 00:05:40,790 look right. 82 00:05:41,180 --> 00:05:45,650 So from here, you could clearly see if we step in to a function. 83 00:05:45,980 --> 00:05:52,100 OK, if you want to analyze the values of available which are local to certain function, then you need 84 00:05:52,100 --> 00:05:54,320 to mandatorily step in to a function. 85 00:05:54,620 --> 00:06:00,950 And then you could analyze the while right now, something interesting to observe over here is the only 86 00:06:00,950 --> 00:06:07,040 difference between the previous function that is at 39 squares in an act that we haven't utilized a 87 00:06:07,050 --> 00:06:08,120 global variable, right? 88 00:06:08,150 --> 00:06:12,320 But here you could really see we are utilizing a global rating, right? 89 00:06:12,560 --> 00:06:18,320 So if you just step inside the square function, let's see whether we will do an the global rating, 90 00:06:18,320 --> 00:06:18,630 right? 91 00:06:18,650 --> 00:06:21,830 So we will be utilizing step into. 92 00:06:22,400 --> 00:06:22,760 OK. 93 00:06:23,180 --> 00:06:29,900 So as we enter into the square function, you could see the variable which are local to square are been 94 00:06:30,140 --> 00:06:35,390 reflected in any area would be right to be happy and square 10, which have been added in. 95 00:06:35,390 --> 00:06:36,080 And they will be. 96 00:06:36,130 --> 00:06:40,760 But we are not seeing a global edible over here, right? 97 00:06:40,770 --> 00:06:41,090 So. 98 00:06:42,090 --> 00:06:43,020 Whenever we. 99 00:06:44,010 --> 00:06:49,710 I had a global variable inside the functions of the Ed Norton character, medically added into variable 100 00:06:49,710 --> 00:06:55,050 rate, so to analyze them the simplest strategies you will select and a variable. 101 00:06:55,330 --> 00:07:02,100 Right now we have selected it right click and then you have an option to add to watch expression. 102 00:07:02,550 --> 00:07:05,840 So we'll just be adding an expression and then click, OK. 103 00:07:05,880 --> 00:07:08,490 So here we just need to specify the name of the variable. 104 00:07:08,490 --> 00:07:09,180 Click OK. 105 00:07:09,510 --> 00:07:14,060 And then you could see that we have one more tab, which is either that is expression. 106 00:07:14,070 --> 00:07:18,890 OK, so the breakpoint highlight the specific position where we have had it every point. 107 00:07:19,260 --> 00:07:26,100 Variable indicator variables which are local to the specific function where we are in an expression 108 00:07:26,100 --> 00:07:29,550 is used to analyze the user defined expression. 109 00:07:29,700 --> 00:07:34,170 OK, so this may include the global variable right here. 110 00:07:34,440 --> 00:07:40,440 So global is not been included even when we are inside the square right now, if we just try to execute 111 00:07:40,440 --> 00:07:41,880 by utilizing step into. 112 00:07:42,630 --> 00:07:43,800 OK, so now. 113 00:07:44,740 --> 00:07:51,160 You could see the values of labor, so if you just updated the values of labor, you could actually 114 00:07:51,160 --> 00:07:53,160 reflect the changes you were here. 115 00:07:53,770 --> 00:07:54,040 Right? 116 00:07:54,700 --> 00:07:56,080 So this is the strategy. 117 00:07:56,080 --> 00:08:02,080 Then you want to analyze a user defined expression or a global view, but you need to take the help 118 00:08:02,080 --> 00:08:03,640 off and watch expression, right?
