Time Narration
00:01 Hello and welcome to the spoken tutorial on Question Glues in KTurtle.
00:08 In this tutorial, we will learn the following question glues and, not.
00:16 To record this tutorial, I am using:

Ubuntu Linux OS version 12.04 KTurtle version 0.8.1 beta.

00:29 We assume that you have basic working knowledge of KTurtle and “if-else” statement in KTurtle.
00:39 If not, for relevant tutorials, please visit our website:

http://spoken-tutorial.org

00:46 Before proceeding, let me explain about question glue words.
00:51 Question glue words enable us to glue small questions into one big question.
01:00 “and”, “or” and “not” are some glue words. Glue words are used together with 'if-else' conditions.
01:11 Let's open a new KTurtle Application.
01:15 Click on Dash home.
01:18 In the Search bar, type: "kturtle"
01:22 and click on the option.
01:24 Let's begin the tutorial with glue word "and".
01:28 I already have a program in a text-editor.
01:33 Let me copy the code from the text editor and paste it into KTurtle editor.
01:40 Please pause the tutorial here and type the program into your KTurtle editor.
01:46 Resume the tutorial after typing the program.
01:50 Let me zoom into the program text.
01:52 It may possibly be a little blurred.
01:56 Let's look at the code.
01:59 reset command sets Turtle to its default position.
02:04 Message in a program is given within double quotes after the keyword "message" .
02:10 “message” command takes string as input.
02:14 It shows a pop-up dialog-box containing text from the string and also generates a beep for non-null strings.
02:24 $a, $b and $c are variables that store user input.
02:30 “ask” command prompts for user input, to be stored in variables.
02:36 if(($a+$b>$c) and ($b+$c>$a) and ($c+$a>$b), checks the “if” condition.
02:49 When the two questions glued with “and” are true, result is true.
02:55 'if(($a != $b) and ($b != $c) and ($c != $a)) checks the "if" condition.
03:05 when 'if' condition above is true, control moves into nested if block.
03:12 It checks whether sides of triangle are unequal.
03:17 fontsize 18 sets the font-size used by print command.
03:22 go 10,100 commands Turtle to go 10 pixels from left of canvas and 100 pixels from top of canvas.
03:35 print command displays the string after checking the 'if' condition.
03:41 'else' command checks else condition when 'if' condition in the block is false.
03:48 'print' command displays the string after checking the else condition.
03:54 'else' command checks the final condition.
03:57 Here, else is checked only when above conditions are false.
04:03 print command displays the string after checking the 'else' condition. I will run the code to check all the conditions.
04:12 Let's click on the Run button to run the program.
04:15 A message dialog-box pops-up. Let me click OK.
04:20 Let's enter 5 for length of AB and click OK,
04:25 8 for length of BC and click OK,
04:29 9 for length of AC and click OK.
04:33 “A scalene triangle” is displayed on the canvas.
04:37 Let's run again.
04:40 A message dialog-box pops up. Let me click OK.
04:44 Let's enter 5 for length of 'AB' and click OK, 6 for length of 'BC' and click OK, 6 for length of 'AC' and click OK.
04:58 “Not a scalene triangle” is displayed on the canvas.
05:02 Let's run again to check default condition.
05:06 A message dialog-box pops up. Let me click OK.
05:11 Let's enter 1 for length of 'AB' and click OK,
05:16 1 for length of 'BC' and click OK,
05:20 2 for length of 'AC' and click OK.
05:24 "Does not satisfy triangle's inequality" is displayed on the canvas.
05:30 Let's now clear this program. Let me type "clear" command and run. clear command cleans the canvas.
05:40 Let's next work with "not" condition.
05:43 Let me copy the program from the text-editor and paste it into KTurtle editor.
05:51 Please pause the tutorial here and type the program into your KTurtle editor.
05:56 Resume the tutorial after typing the program.
06:01 Let me zoom into the program text and explain the program.
06:05 reset command sets Turtle to default position.
06:09 $a, $b and $c are variables that store user input.
06:15 if not(($a==$b)and($b==$c)and ($c==$a)) checks the if not condition.
06:27 "not" is a special question glue-word. It inverses the logical state of its operand.
06:36 e.g. If the given condition is "true", "not" makes it "false"
06:42 and when the condition is false, the output will be true.
06:48 print command displays the string after checking the if not condition.
06:55 else command is executed when if condition is false.
07:01 print command displays the string after checking the else condition.
07:07 go 100,100 commands Turtle to go 100 pixels from left of canvas and 100 pixels from top of canvas.
07:20 repeat 3{turnright 120 forward 100} commands turtle to draw an equilateral triangle on the canvas.
07:32 Let me run the program to check all the conditions.
07:36 Press F5 key to run the code.
07:40 Enter 6 for length of AB and click OK.
07:45 Enter 5 for length of BC and click OK.
07:48 Enter 7 for length of AC and click OK.
07:54 “Triangle is not equilateral” is displayed on the canvas.
07:58 Let's run again. Let's enter 5 for length of AB and click OK,
08:05 5 for length of BC and click OK,
08:09 5 for length of AC and click OK.
08:13 “Triangle is equilateral” is displayed on the canvas. An equilateral triangle is drawn on the canvas.
08:21 With this we come to the end of this tutorial.
08:25 Let's summarize.
08:28 In this tutorial, we have learnt the question glues- "and", "not".
08:35 As an assignment, I would like you to write program to determine-
08:40 Angle concept for right angled triangle using question glue “or”
08:48 Structure of "if or" condition is:
08:51 if within brackets condition or within brackets condition or within brackets condition.
08:59 Within curly brackets do something
09:02 else within curly brackets do something.
