WEBVTT 00:00.600 --> 00:06.660 So now let's actually start implementing hangman. 00:06.780 --> 00:10.880 So start with step 1 and mean here. 00:11.150 --> 00:12.870 So we have 00:15.840 --> 00:20.160 here is going to do exactly what we did with number gassers. 00:20.160 --> 00:31.850 While I want to play again don't have those functions yet but we make them in. 00:32.200 --> 00:33.070 OK. 00:33.310 --> 00:34.460 That is our step. 00:34.480 --> 00:39.110 One of our top down design right here. 00:40.040 --> 00:43.350 So do it again. 00:43.360 --> 00:47.960 While I want to play again just like we had with number Yassar. 00:48.320 --> 00:54.130 So let's though or declare those functions top here. 00:55.930 --> 01:11.940 What do you say with the name and would want to play an. 01:12.110 --> 01:13.180 There you go. 01:13.730 --> 01:22.240 So next thing I want to do is want to define plaguing 01:26.310 --> 01:27.150 k. 01:27.300 --> 01:28.040 Phew. 01:29.150 --> 01:36.180 Remember what we need to do is have the get the secret phrase make the hidden phrase right. 01:36.180 --> 01:41.040 The one that dashes in and set the number of guesses left and so on. 01:41.090 --> 01:45.320 So let's do this do these three steps first. 01:45.860 --> 01:56.010 So going to need some kind of a C string for the secret where secret phrase 01:58.580 --> 02:07.970 that and it's going to be an array because Raffa read this from the user or from the player self. 02:08.030 --> 02:14.310 So I need to have some kind of like Max link. 02:14.580 --> 02:16.510 It's great. 02:16.960 --> 02:18.480 Us. 02:18.690 --> 02:25.220 And again to set it to some some number do too much just make it long enough. 02:25.610 --> 02:26.810 Why. 02:29.570 --> 02:29.820 CH 02:32.860 --> 02:36.660 reas this way. 02:36.960 --> 02:46.980 And we're also going to have a C string but this is going to be a character pointer to the hidden phrase 02:46.990 --> 02:53.430 because we're going to make this from heap memory. 02:54.470 --> 02:55.620 So with that. 02:55.650 --> 02:57.540 And we have 03:00.900 --> 03:07.620 in this number of guess it's life. 03:08.300 --> 03:14.580 And we are we make this into a constant and smacks 03:16.770 --> 03:19.280 guess's. 03:19.590 --> 03:20.980 Six is 03:34.870 --> 03:45.530 simple so far so we just all we've done is made the variables that we need so we need to actually get 03:45.530 --> 03:51.570 the secret phrase and make the hidden phrase and so on. 03:51.570 --> 03:54.080 So let's do that. 03:54.090 --> 03:57.270 So say 04:01.620 --> 04:10.550 secret or sorry get secret phrase 04:14.800 --> 04:18.960 this and will pass in the secret phrase 04:21.840 --> 04:24.060 and the wink. 04:24.340 --> 04:31.360 Or the maximum number of characters you know great great. 04:31.630 --> 04:32.290 This 04:35.310 --> 04:35.910 care. 04:36.250 --> 04:45.440 So this function will be exactly the same as what we did in the dynamic memory practice. 04:46.060 --> 04:49.780 So are at least very similar. 04:51.950 --> 04:54.530 So let's rate this once. 04:58.920 --> 05:05.230 You're point to it's not going to turn anything right because we're passing in a an array so that will 05:05.230 --> 05:09.900 actually change the array rates raise is passed by reference. 05:09.940 --> 05:16.770 So we're going to change this phrase by adding all the characters in here. 05:17.300 --> 05:21.720 So it's phrase 05:24.930 --> 05:32.180 phrased like this and we're passing a character. 05:33.320 --> 05:33.790 Ray 05:36.850 --> 05:44.150 is this and passed back the maximum way. 05:45.050 --> 05:48.440 Max link back 05:52.360 --> 05:54.410 to find it here 05:59.360 --> 06:00.450 right now. 06:00.930 --> 06:04.920 Yes it's phrase 06:14.800 --> 06:19.570 XBLA. 06:19.700 --> 06:19.960 Hey 06:26.720 --> 06:34.370 And essentially all we're going to do is exactly what we did before 06:37.210 --> 06:40.310 say bhool aliar. 06:40.400 --> 06:40.660 Right. 06:40.670 --> 06:44.710 Just like regular input. 06:46.550 --> 06:47.890 This do 06:51.450 --> 06:57.390 while there's failure which should seem all too familiar. 06:59.690 --> 07:01.940 An failure 07:04.990 --> 07:09.650 to false. 07:09.900 --> 07:10.890 Out. 07:12.360 --> 07:23.690 These enter the Secret Ch phrase we're not using the functions we had we made before in the erate practice. 07:24.040 --> 07:29.210 But we will not for this one anyway but we will be using it. 07:30.460 --> 07:37.920 Get ch as it is and the maximum 07:41.840 --> 07:44.860 Just like we had in the practice day. 07:45.050 --> 07:48.930 If you fail rate 07:53.120 --> 08:03.420 then we should it's clear C nor in need 08:06.740 --> 08:11.130 our constants appear. 08:11.440 --> 08:18.750 Nor are as many and just enough 08:21.290 --> 08:21.730 are 08:24.520 --> 08:25.760 char's this 08:31.810 --> 08:42.350 and once actually have a number constant that's going to be like an integer constants going to be a 08:43.710 --> 08:45.220 star constant. 08:45.770 --> 08:50.600 It's going to be the inputs air string when you use that 08:55.620 --> 08:57.410 input error. 08:58.720 --> 09:01.720 Please try again. 09:03.500 --> 09:06.950 You can also have césarine constants too. 09:06.960 --> 09:13.460 So it doesn't have to be just integers or floats or anything like that can actually have this small 09:16.310 --> 09:18.730 in space. 09:18.800 --> 09:19.250 It's 09:22.040 --> 09:22.480 here. 09:22.480 --> 09:31.980 String all this and we failed here in this case write failure. 09:32.040 --> 09:33.170 It's true. 09:36.920 --> 09:39.750 Otherwise. 09:40.590 --> 09:43.010 So what happened. 09:43.130 --> 09:49.590 What would happen if the length of what the input zero. 09:49.860 --> 09:50.160 Right. 09:50.160 --> 09:53.350 So what if they said Please enter a phrase. 09:53.370 --> 09:55.630 But then they just press enter. 09:55.930 --> 09:58.030 And this would still work. 09:58.110 --> 10:00.650 However it would be there would be nothing. 10:00.660 --> 10:04.760 So we want to make sure that doesn't happen. 10:04.770 --> 10:13.260 So we're going to actually get the length of this phrase and check to see if it's zero and if it is 10:13.680 --> 10:21.150 then we're going to print out something and then make sure they do it again. 10:21.570 --> 10:26.000 So what some say to that. 10:26.020 --> 10:34.390 So for this I need this string to be able to get the link that says doing this. 10:34.720 --> 10:44.650 There And here we're going to say have the link. 10:45.270 --> 10:52.180 All right here a link to us for Lion 10:56.320 --> 11:01.210 of secret is 11:04.020 --> 11:15.610 this and so if the link is zero then we're going to output. 11:16.100 --> 11:23.070 Just put something directly here so I'm not going to say it's an input air I'm going to say you must 11:24.920 --> 11:30.560 enter a word that's longer 0 do it's 11:33.230 --> 11:34.120 Please try 11:37.640 --> 11:40.990 this. 11:41.000 --> 11:44.090 And this was failure to this case 11:54.480 --> 11:55.350 and 12:00.920 --> 12:04.720 we should also pass back the link of the secret phrase actually. 12:04.730 --> 12:06.830 So let's actually change this. 12:07.200 --> 12:07.560 It 12:11.640 --> 12:15.350 or know how long it is not to do this every time. 12:16.840 --> 12:18.910 It's just that. 12:19.950 --> 12:20.500 Turn the 12:24.040 --> 12:25.870 we know it has to be greater than zero. 12:25.880 --> 12:29.510 Otherwise it will be looped again. 12:29.570 --> 12:34.820 So that's this one so we need a variable for the length. 12:37.410 --> 12:38.150 Here 12:41.830 --> 12:49.790 secret phrase length is get that from here. 12:51.590 --> 12:55.470 So next we should. 12:55.850 --> 13:05.030 One thing you want to do is actually paste in the functions we made from the array lecture or from the 13:05.030 --> 13:06.230 array practice lecture. 13:06.230 --> 13:18.180 So we had that those two functions called Get character and use these already have them in my clipboard. 13:18.490 --> 13:23.640 So we had these ones of good character which you could have a prompt in error. 13:23.650 --> 13:27.890 These are directly from that array lecture. 13:28.240 --> 13:30.930 I didn't change them in any way. 13:30.970 --> 13:38.230 So if you remember this you can get them at the prompt in the air and it checks to see if it's an alpha 13:38.320 --> 13:39.870 you need to. 13:40.640 --> 13:43.990 And also check to see if it's lower case. 13:46.130 --> 13:52.610 Well this won't really matter too much after we fix this so. 13:53.130 --> 13:58.270 And he could also give the give it's some valid input too. 13:58.410 --> 14:00.140 And like what. 14:00.340 --> 14:08.560 OK so let's we have to include CC type because otherwise it will work clewed 14:10.940 --> 14:15.230 type this way. 14:15.900 --> 14:19.710 And this is just so we have it and can use it. 14:19.710 --> 14:24.050 So for the next one is 14:27.000 --> 14:36.980 hidden word so are hidden phrase hidden phrase because to say make hidden. 14:38.550 --> 14:41.070 We're going to pass the secret phrase 14:43.480 --> 14:50.310 and the secret free. 14:50.420 --> 14:55.650 And this is why I have the secret phrase like just as for this function. 14:56.000 --> 15:02.600 So it's copy this and declare it of 15:08.540 --> 15:15.070 and this will pass back a character pointer of the new memory that we make. 15:16.040 --> 15:20.640 So this would be Comte's shore star 15:24.320 --> 15:25.160 and 15:30.250 --> 15:32.050 it's this 15:40.300 --> 15:44.370 and put it it's and these will be the last. 15:44.570 --> 15:45.890 It's right here. 15:47.270 --> 15:48.780 Make hidden free. 15:48.790 --> 15:49.160 It's 15:53.140 --> 15:53.950 so 15:57.470 --> 15:59.070 do it is. 15:59.300 --> 16:03.950 Let's take a look at the key phrase here. 16:03.960 --> 16:04.170 Right. 16:04.160 --> 16:12.500 So making news E-string given the length of the phrase and then set all the dashes this should exclude 16:12.510 --> 16:14.510 actually the 16:17.740 --> 16:18.780 spaces. 16:18.850 --> 16:21.300 So we haven't taken that into account. 16:21.430 --> 16:26.000 We will in the function itself so this 16:29.370 --> 16:47.910 char star also a hidden phrase called new char secret phrase link was one always plus one seed in all 16:47.920 --> 16:50.500 character. 16:50.730 --> 16:56.520 So it's wrong. 16:56.640 --> 17:09.130 So for int i zero I's less than Lenk secret reads like 17:12.220 --> 17:15.260 Spross. 17:15.460 --> 17:32.360 And so if the secret were a secret phrase is not equal to a space then we will set the hidden or hidden 17:34.440 --> 17:42.000 spell phrase hidden phrase of will be the dash and 17:45.360 --> 17:51.250 otherwise if it is then we'll just kind of set it to be the same thing as in phrase. 17:51.350 --> 17:51.630 I 17:56.500 --> 18:06.460 just say dash or space here Gaelic that and again remember didn't phrase 18:11.320 --> 18:13.650 of the last one. 18:13.780 --> 18:14.380 The secret 18:17.440 --> 18:23.040 fragrance link should be 18:26.780 --> 18:27.700 the null character. 18:27.750 --> 18:28.170 Remember 18:32.880 --> 18:42.410 turn the hidden phrase and in fact in the game you should do instead is a pointer right. 18:47.040 --> 18:47.340 Point 18:50.590 --> 18:52.400 like that because we own it. 18:52.400 --> 18:57.130 So play game owns the hidden phrase memory. 18:57.650 --> 19:07.250 So you have to remember this so we know that we we as in play game has to delete it later. 19:09.090 --> 19:11.190 So what's next. 19:11.220 --> 19:28.080 So now that we have all of that we shifted to rob the poor to using the number of guesses left and the 19:28.080 --> 19:32.050 hidden phrase. 19:32.720 --> 19:41.920 So you're saying Gironde board and we're going to use 19:46.470 --> 19:49.200 yes is laugh. 19:50.560 --> 19:54.580 And you'll see why raising a number of guests is left his second and the 19:57.840 --> 19:58.670 pointer 20:01.190 --> 20:06.180 phrase. 20:06.370 --> 20:07.320 Copy this 20:14.720 --> 20:19.810 peer to set it. 20:24.140 --> 20:32.490 And Sarber venture I think because we're just drawing stuff and there say in here and Charsadda Star 20:32.490 --> 20:34.020 year. 20:34.250 --> 20:43.460 And we don't need the link for this because then we could just use sterling césarine and probably don't 20:43.460 --> 20:45.220 want to change it either. 20:46.140 --> 20:47.040 All right. 20:47.090 --> 20:50.930 So you put Konst year. 20:51.810 --> 20:53.550 So this 21:06.490 --> 21:08.060 and it's 21:11.640 --> 21:12.210 your 21:15.740 --> 21:28.440 like that's so we didn't actually do a top down design for the DRob board at all but we should be able 21:28.440 --> 21:32.260 to easily figure this out right. 21:32.490 --> 21:38.590 So what we want to do is check to see how many guesses we have left. 21:39.600 --> 21:51.660 And then based on that we want to draw the gallows and the guy if there is if it's not six guesses say 21:52.380 --> 21:55.090 so what. 21:55.110 --> 22:03.210 Start doing that and we're going to use a switch statement actually and switch on the number of guesses 22:03.230 --> 22:03.720 lasht 22:08.720 --> 22:15.880 and for this case zero will be 22:19.280 --> 22:20.490 the break. 22:21.020 --> 22:21.600 OK. 22:21.670 --> 22:31.390 So caesura will be they have 0 guesses left so we should draw the entire Gallo's with the guy. 22:31.620 --> 22:36.910 So that so put a space in between. 22:36.920 --> 22:49.120 And there should be three dashes and two different signs that the whole copy what I'm doing. 22:49.160 --> 22:54.960 Hope you're following along anyway. 22:56.370 --> 22:58.270 It's boring to watch. 22:58.270 --> 22:58.680 I think 23:03.130 --> 23:08.820 so for the head to use an Oh. 23:09.150 --> 23:10.610 I don't know maybe a capital 23:13.970 --> 23:14.330 better 23:23.150 --> 23:33.630 body stick that and of course Actually since this is this is going to be the case where we're showing 23:33.690 --> 23:44.370 the whole body of the arm like here and then need two two dashes here because this is the escape character 23:44.430 --> 23:50.540 and we have to escape the arm so it'll actually look like this when it draws but you need to do it like 23:50.620 --> 23:52.310 that. 23:52.530 --> 23:54.900 Just like we have like Dash or slash. 23:54.900 --> 24:02.800 And for a new line we have to do slash slash slash for this backslash. 24:02.990 --> 24:03.260 So 24:09.740 --> 24:11.470 it's just this 24:14.070 --> 24:19.840 and slash slash leg. 24:21.920 --> 24:24.290 Dasch in Los 24:27.070 --> 24:30.290 dash OK. 24:30.410 --> 24:37.210 So we should be copying this whole thing and we have to do this for each case now. 24:37.260 --> 24:42.330 So Case 1 and will remove one part of it. 24:42.440 --> 24:48.990 So remove the leg in this case the leg will be the last thing you see. 24:51.900 --> 24:55.420 Case to 25:05.060 --> 25:06.320 move the 25:09.340 --> 25:16.930 speed the body and the hands her arms case three 25:24.410 --> 25:25.610 it will be 25:27.720 --> 25:32.710 the his left arm is gone. 25:32.910 --> 25:34.410 Here this 25:41.830 --> 25:43.140 is right here. 25:47.130 --> 25:49.580 The key is for 25:58.430 --> 26:05.060 he will remove his other arm which is body that 26:09.390 --> 26:12.570 and Caze five 26:28.470 --> 26:31.800 move the body. 26:31.820 --> 26:36.100 This is the head. 26:36.290 --> 26:37.920 He's 6 26:41.430 --> 26:42.030 ye 26:53.300 --> 26:55.000 yes the gallows 27:00.480 --> 27:02.550 so we understand what's happening here. 27:02.580 --> 27:09.190 We're just switching based off the number of guesses and then we're going to do the output for. 27:09.820 --> 27:13.300 For that value. 27:14.040 --> 27:22.590 That's really it and so it defaults. 27:22.840 --> 27:24.920 Deif all we have nothing. 27:29.710 --> 27:32.550 And we should also output
