195 00:13:20,990 --> 00:13:31,100 So and so what happened is generally this is minus 128, then minus 127, 126 and 127. 196 00:13:31,820 --> 00:13:40,730 So when you are standing here and if you do plus one, 127 plus one, so you will reach here. 197 00:13:43,200 --> 00:13:48,390 Okay, so you are standing at 127, and if you look plus one, you will reach here. 198 00:13:48,750 --> 00:13:50,400 This thing is called wrap around. 199 00:13:52,190 --> 00:13:52,460 Rep. 200 00:13:53,490 --> 00:13:53,910 Around. 201 00:13:57,540 --> 00:14:03,100 OK, so one 27 plus one is minus 128. 202 00:14:03,960 --> 00:14:11,850 Similarly went on to say one plus two is minus 127, went on the seven plus three and it goes to minus 203 00:14:11,850 --> 00:14:12,690 126. 204 00:14:13,320 --> 00:14:15,510 So in this case, this will lose 130. 205 00:14:16,740 --> 00:14:21,000 So the character corresponding to 130 is getting stored in S.H.. 206 00:14:21,240 --> 00:14:25,510 And that character is mapped with minus 126. 207 00:14:25,920 --> 00:14:26,150 OK. 208 00:14:27,690 --> 00:14:32,190 So, for example, if you ride can H is it goes to 127. 209 00:14:32,790 --> 00:14:38,730 So the character corresponding to 127 is stored in variable C h. 210 00:14:40,040 --> 00:14:47,420 And then if you do see H equals C, H plus one, that is 127 plus one, which will be close to minus 211 00:14:47,420 --> 00:14:49,430 128 due to wrap around. 212 00:14:50,370 --> 00:14:55,940 So minus went on there, the correct corresponding to minus 128 will be stored in variable C h. 213 00:14:56,360 --> 00:14:58,660 And if you print C, H. 214 00:14:59,360 --> 00:15:03,530 So that correctively blueprinted which is mapped to minus 128. 215 00:15:05,390 --> 00:15:08,660 So this wrap around things happens with another diaper as well. 216 00:15:09,080 --> 00:15:11,990 For example, I told you that the range of integers. 217 00:15:13,190 --> 00:15:20,090 Is from minus two to the power 31 to that about her division minus one. 218 00:15:20,120 --> 00:15:21,390 So this was the range of. 219 00:15:23,160 --> 00:15:25,620 So actually, this thing is called into Max. 220 00:15:29,310 --> 00:15:30,990 And this thing is called Anderman. 221 00:15:33,820 --> 00:15:35,800 So here I am having Anderman. 222 00:15:37,080 --> 00:15:38,610 And you have intermix here. 223 00:15:44,700 --> 00:15:49,770 So if we will add plus one to the endemics, you will reach Intiman. 224 00:15:51,200 --> 00:15:53,070 OK, so this is a wrap around. 225 00:15:56,980 --> 00:15:58,170 And the bank says nothing. 226 00:15:58,290 --> 00:16:00,410 It is just good, it's about doing minus one. 227 00:16:00,720 --> 00:16:04,280 This value has been given some name and that name is in the banks. 228 00:16:04,380 --> 00:16:05,810 Similarly, in is nothing. 229 00:16:06,660 --> 00:16:08,940 It is minus two to the power 31. 230 00:16:09,270 --> 00:16:12,600 It is just Antoin is just the name of this value. 231 00:16:14,610 --> 00:16:17,580 OK, so now let's talk about explicit typecasting. 232 00:16:18,510 --> 00:16:21,750 So implicit typecasting was which was done automatically. 233 00:16:21,870 --> 00:16:23,010 We are not doing anything. 234 00:16:23,280 --> 00:16:25,260 It is done automatically by the compiler. 235 00:16:26,220 --> 00:16:30,540 So I told you, remember this thing flawed. 236 00:16:31,320 --> 00:16:32,760 Then you have integers. 237 00:16:33,030 --> 00:16:34,290 Then you have characters. 238 00:16:34,380 --> 00:16:35,340 And then you have bull. 239 00:16:37,020 --> 00:16:38,400 So from lower to upper. 240 00:16:39,510 --> 00:16:40,740 From lower to upper. 241 00:16:43,880 --> 00:16:49,790 This is called implicit typecasting because these type conclusion are done automatically by the compiler. 242 00:16:50,180 --> 00:16:53,180 But what if I want to do the reverse? 243 00:16:54,050 --> 00:16:56,990 I want to convert integer to character. 244 00:16:57,770 --> 00:16:58,880 So we are doing the reverse. 245 00:16:59,330 --> 00:17:01,850 So this thing will be called explicit typecasting. 246 00:17:03,520 --> 00:17:05,770 OK, so let's see an example. 247 00:17:12,920 --> 00:17:14,610 So for explicit typecasting. 248 00:17:14,760 --> 00:17:15,560 What you will do. 249 00:17:17,650 --> 00:17:18,710 Commander Daoud also. 250 00:17:22,050 --> 00:17:28,240 So for explicit typecasting, what you will do, for example, you are having gay S.H.. 251 00:17:29,820 --> 00:17:32,970 It goes like character. 252 00:17:34,440 --> 00:17:41,640 Suppose you want to find you want to convert this character into integer. 253 00:17:41,660 --> 00:17:42,000 You will. 254 00:17:42,150 --> 00:17:42,750 What you will do. 255 00:17:42,780 --> 00:17:44,410 You will just write in. 256 00:17:45,430 --> 00:17:47,360 And then you will write to S.H.. 257 00:17:49,140 --> 00:17:51,690 So this thing is called explicit typecasting. 258 00:17:52,590 --> 00:17:55,380 So what is the value of variable? 259 00:17:55,390 --> 00:17:55,740 Well. 260 00:17:59,430 --> 00:18:01,650 It is nothing but 65. 261 00:18:02,170 --> 00:18:05,010 OK, so let's build and lemon. 262 00:18:08,450 --> 00:18:10,530 Sixty 65 is getting printed. 263 00:18:11,100 --> 00:18:11,330 OK. 264 00:18:11,730 --> 00:18:15,000 So this is called explicit typecasting. 265 00:18:15,240 --> 00:18:16,900 We are typecasting ourself. 266 00:18:20,610 --> 00:18:28,650 Let's take let's take one more example, for example, voodoo will be a true. 267 00:18:34,850 --> 00:18:37,640 And X equals. 268 00:18:41,010 --> 00:18:41,720 Typecast. 269 00:18:42,490 --> 00:18:42,860 B. 270 00:18:44,260 --> 00:18:46,810 And then you are printing the value of X. 271 00:18:46,960 --> 00:18:48,130 So what do I my output. 272 00:18:50,110 --> 00:18:51,220 My output will be one. 273 00:18:55,900 --> 00:18:57,020 So when is getting printed? 274 00:18:57,040 --> 00:18:57,540 Why, when? 275 00:18:58,090 --> 00:19:01,660 Because through means one false means zero simple. 276 00:19:03,340 --> 00:19:04,810 Now, let's see one more example. 277 00:19:08,320 --> 00:19:11,400 And way equals 70. 278 00:19:13,980 --> 00:19:14,440 S.H.. 279 00:19:15,880 --> 00:19:16,980 It was. 280 00:19:21,260 --> 00:19:25,380 Why and then you are printing C.H.. 281 00:19:26,060 --> 00:19:27,230 So where to live my output. 282 00:19:29,950 --> 00:19:32,160 So the value of variable Y is seventy. 283 00:19:32,210 --> 00:19:35,240 And then you'll come out doing that seven days into a character. 284 00:19:35,690 --> 00:19:38,030 So the character mapped with 70 will get printed. 285 00:19:41,290 --> 00:19:42,720 So there is an error in this line. 286 00:19:42,790 --> 00:19:43,840 Oh, so that it is. 287 00:19:43,960 --> 00:19:45,890 We have already declared the variable C.H.. 288 00:19:46,720 --> 00:19:49,480 So let's change the name ABC. 289 00:19:53,620 --> 00:19:57,970 A B.S., OK, so you can't have two variables with the same name. 290 00:20:02,550 --> 00:20:05,980 So their character maybe with the 70s Capital F.. 291 00:20:07,390 --> 00:20:10,170 OK, so what is the problem? 292 00:20:10,740 --> 00:20:12,270 What is the problem with typecasting? 293 00:20:12,420 --> 00:20:13,850 So the problem is very simple. 294 00:20:16,370 --> 00:20:19,460 Flawed and. 295 00:20:21,190 --> 00:20:21,600 Gad. 296 00:20:22,740 --> 00:20:30,810 And, Wolf, if you're going from lower to upper, if you're converting any lower into upper, in that 297 00:20:30,810 --> 00:20:32,220 case, we don't have any problem. 298 00:20:32,230 --> 00:20:34,800 For example, if you want to convert. 299 00:20:34,830 --> 00:20:38,430 If you want to typecast the character into Integer, what will happen? 300 00:20:38,460 --> 00:20:43,080 This is of one byte and then integer is of four bytes. 301 00:20:44,520 --> 00:20:49,190 So this one bite can easily be copied in this integer. 302 00:20:50,100 --> 00:20:56,580 But as soon as you try and reverse, for example, you want to convert integer in a character in the 303 00:20:56,580 --> 00:21:03,720 last example where there did something like this, also what we did and divide was 70 and. 304 00:21:04,770 --> 00:21:05,880 Can ABC. 305 00:21:08,580 --> 00:21:09,250 Care, right? 306 00:21:09,960 --> 00:21:11,280 So if you want to do this. 307 00:21:12,020 --> 00:21:13,350 So what are you doing? 308 00:21:16,180 --> 00:21:24,130 This is why four bites, and this is my character, just one bite and were destroyed, Windows doing 309 00:21:25,240 --> 00:21:27,530 it will copy only one bite. 310 00:21:30,030 --> 00:21:33,720 Into the character and all this data will be lost. 311 00:21:36,400 --> 00:21:40,400 OK, so in this case, my data is not lost because the variable. 312 00:21:40,510 --> 00:21:46,700 Well, because the variable Y is containing small value and 70 can be written in eight bytes. 313 00:21:46,820 --> 00:21:47,900 So this is Edwards. 314 00:21:49,430 --> 00:21:52,080 And the remaining is gurantee forwards. 315 00:21:53,080 --> 00:21:56,910 So 70 can be written in eight, which that's why there is no details. 316 00:21:57,320 --> 00:22:04,790 But if the number was very large, for example, let's say if the number was this and then if you typecast 317 00:22:04,850 --> 00:22:08,000 this integer into a character, then there will be a detailers. 318 00:22:09,220 --> 00:22:09,460 OK. 319 00:22:10,120 --> 00:22:14,080 So I hope you come to know what is implicit and explicit typecasting. 320 00:22:14,860 --> 00:22:17,710 Typecasting means which is done automatically by the compiler. 321 00:22:17,770 --> 00:22:29,740 For example, character Pless in Bajour is an integer integer divided by a flawed is a flawed and indeed 322 00:22:29,740 --> 00:22:33,190 the less flawed is flawed. 323 00:22:34,960 --> 00:22:39,830 Similarly, integer in character is an integer. 324 00:22:41,080 --> 00:22:41,370 Okay. 325 00:22:42,130 --> 00:22:43,060 And a character. 326 00:22:43,060 --> 00:22:45,040 Pless character is also an integer. 327 00:22:46,360 --> 00:22:50,640 In this case, that Abbadon possibility's there and an explicit typecasting. 328 00:22:50,650 --> 00:22:51,340 What will do? 329 00:22:51,910 --> 00:22:54,270 For example, you will write GABSI h. 330 00:22:54,430 --> 00:22:56,480 As it goes to typecast into character. 331 00:22:57,130 --> 00:23:01,990 And if let's say and Y equals 10, it will write something like this. 332 00:23:02,240 --> 00:23:04,180 Okay, so this is explicit. 333 00:23:06,880 --> 00:23:09,360 We are converging in this case. 334 00:23:09,420 --> 00:23:10,680 This is called implicit. 335 00:23:11,340 --> 00:23:13,350 It is done automatically by the compiler. 336 00:23:13,710 --> 00:23:16,530 And the last thing today that we learned is wrap around. 337 00:23:18,150 --> 00:23:25,530 OK, if you're standing at the maximum value and you will add blessin, you will reach the minimum value. 338 00:23:26,790 --> 00:23:28,830 OK, so this is it for this video. 339 00:23:29,040 --> 00:23:29,850 Thanks for watching.
