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 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 | Hereelse 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 | Lets run again. |
04.40 | A message dialog box pops up .Let me click OK. |
04.44 | Lets 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 draws an equilateral triangle on the canvas |
