217 00:11:39,290 --> 00:11:40,940 It will take an input. 218 00:11:41,420 --> 00:11:43,670 It will take an integer who's a square. 219 00:11:43,880 --> 00:11:44,890 We have to find. 220 00:11:45,800 --> 00:11:49,670 So it will take an integer, let's say, and a. 221 00:11:50,120 --> 00:11:52,400 And we have to find the square of a. 222 00:11:55,300 --> 00:12:01,030 So end answer equals a multiply by a. 223 00:12:02,790 --> 00:12:03,050 OK. 224 00:12:03,440 --> 00:12:07,800 And after calculating the answer, we have to return this answer. 225 00:12:11,180 --> 00:12:14,330 Now, from the mean I will call squared function. 226 00:12:15,500 --> 00:12:18,300 So the vogue of the main was to find the square of a number. 227 00:12:18,650 --> 00:12:20,810 And for that we have made a function. 228 00:12:21,590 --> 00:12:23,110 So we'll take input. 229 00:12:23,600 --> 00:12:25,030 Who's number, who's a square? 230 00:12:25,040 --> 00:12:25,910 We want to find out. 231 00:12:26,360 --> 00:12:27,290 Suppose the number is. 232 00:12:27,320 --> 00:12:29,400 And I want to find this square off. 233 00:12:29,510 --> 00:12:31,820 And so I will call function. 234 00:12:32,280 --> 00:12:34,010 Pasquier function pick. 235 00:12:34,130 --> 00:12:37,370 And as input and find the square of this number. 236 00:12:37,400 --> 00:12:40,970 And this function will return me an integer value. 237 00:12:41,090 --> 00:12:43,340 Which is the square of the given number. 238 00:12:43,880 --> 00:12:48,830 So since this function is returning something, I will have to start it. 239 00:12:49,550 --> 00:12:53,650 So end let's say B into B equals this. 240 00:12:54,520 --> 00:12:54,750 OK. 241 00:12:54,860 --> 00:12:55,410 Why end. 242 00:12:55,550 --> 00:12:57,350 Because this function is returning. 243 00:12:57,740 --> 00:12:58,070 And. 244 00:13:00,050 --> 00:13:05,290 And finally, I can see out be OK. 245 00:13:05,810 --> 00:13:08,930 So we call this thing as a return type. 246 00:13:10,020 --> 00:13:12,660 So this is a done type. 247 00:13:13,520 --> 00:13:15,160 I am returning and deja here. 248 00:13:15,980 --> 00:13:18,750 We call this thing as name of dysfunction. 249 00:13:19,500 --> 00:13:20,700 So this thing is called. 250 00:13:21,620 --> 00:13:24,680 Name of function. 251 00:13:27,300 --> 00:13:34,440 Now, the values that it is taking is called arguments, the values which in my afunction will take 252 00:13:34,440 --> 00:13:35,160 as input. 253 00:13:35,340 --> 00:13:38,820 I've called arguments or against, say, barometer's. 254 00:13:43,400 --> 00:13:47,800 So this thing is called calling the function, we are calling the function square. 255 00:13:47,860 --> 00:13:50,900 And so this is calling function. 256 00:13:53,830 --> 00:13:54,120 OK. 257 00:13:54,480 --> 00:14:06,900 And this whole thing is called this whole thing is called definition of function and definition of function. 258 00:14:09,760 --> 00:14:11,870 OK, so have you noticed one thing? 259 00:14:15,290 --> 00:14:20,090 So if I want to call a function, that function was defined above. 260 00:14:22,100 --> 00:14:26,300 Similarly here, I want to call it a function. 261 00:14:26,630 --> 00:14:29,780 So add function was defined above mean. 262 00:14:31,550 --> 00:14:37,550 And similarly here, if I want to find the square, if I want to call a function square, so squared 263 00:14:37,550 --> 00:14:41,180 function is defined above the mean. 264 00:14:43,150 --> 00:14:50,080 So village to an important result that if our function, if a function. 265 00:14:50,290 --> 00:14:59,260 Let's call this function as a safe, a function vaunt to call it a function, wants to call and enter 266 00:14:59,260 --> 00:15:12,010 function B in a function, wants to call other function B, then B must be declared above A. 267 00:15:14,340 --> 00:15:18,400 Above function a otherwise, what will happen?
