Revision as of 17:07, 18 September 2015

Time Narration
00:01 Hello Everybody.
00:03 Welcome to this tutorial on Control Execution in KTurtle.
00:10 In this tutorial, we will learn
00:13 * 'while' loop and
00:15 * 'for' loop.
00:17 To record this tutorial, I am using:
  • Ubuntu Linux OS Version 12.04
  • KTurtle version 0.8.1 beta.
00:32 We assume that you have basic working knowledge of Kturtle.
00:38 If not, for relevant tutorials, please visit our website:

http://spoken-tutorial.org

00:45 Let's open a new KTurtle Application.
00:48 Click on Dash home.
00:50 In the Search bar, type: "KTurtle".
00:53 Click on the option. KTurtle Application opens.
00:59 Let me first explain about what is control execution.
01:05 'Control execution' is controlling the flow of a program.
01:10 Different conditions are used to control program execution.
01:16 Loop is a block of code executed repeatedly till a certain condition is satisfied.
01:25 E.g. “while” loop and “for” loop.
01:30 Let's begin the tutorial with “while” loop.
01:34 In the “while” loop, the code inside the loop repeats till boolean evaluates to false.
01:42 Let me explain the structure of “while” loop.

while loop condition { 

do something

with loop increment variable }

01:56 I already have the code in a text editor.
01:59 Let me copy the program from text editor and paste it into KTurtle editor.
02:07 Please pause the tutorial here and type the program into your KTurtle editor.
02:13 Resume the tutorial after typing the program
02:18 Let me zoom into the program text, it may possibly be a little blurred.
02:25 Let me explain the code.
02:27 '#' sign comments a line written after it.
02:32 It means, this line will not be executed while running the program.
02:38 reset command sets “Turtle” to its default position.
02:43 $x=0 initializes the value of variable 'x' to zero.
02:52 Message in a program is given within double quotes after the keyword message " ",

“message” command takes “string” as input.

03:04 It shows a pop-up dialog box containing text from the string.
03:11 while $x<30 checks the “while” condition,
03:17 $x=$x+3 increments the value of variable $x by 3.
03:27 fontsize 15 sets the font-size used by print command.
03:35 fontsize takes number as input, set in pixels.
03:42 forward 20 commands “Turtle” to move 20 steps forward on the canvas.
03:52 print $x displays the value of variable 'x' on the canvas.
04:01 Let me click on the “Run” button to run the program.
04:05 A message dialog box pops up. Let me click OK.
04:11 Multiples of 3, from 3 to 30, are displayed on the canvas.
04:17 “Turtle” moves 20 steps forward on the canvas.
04:22 Let's next work with “for” loop.
04:26 “for” loop is a counting loop.
04:29 Every time the code inside “for” loop is executed,
04:34 variable value is incremented till it reaches the end value.
04:41 Let me explain the structure of “for” loop.
04:46 for variable = start number to end number { Statement}
04:55 Let me clear the current program.
04:59 Let me type clearcommand and run to clean the canvas.
05:05 Let me copy the program from text editor and paste it into 'KTurtle editor'.
05:14 Please pause the tutorial here and type the program into your KTurtle editor.
05:20 Resume the tutorial after typing the program.
05:25 Let me zoom into the program text, it may possibly be a little blurred.
05:32 Let me explain the program.
05:34 '#' sign comments a line written after it.
05:39 reset command sets “Turtle” to its default position.
05:44 $r=0 initializes the value of variable 'r' to zero.
05:52 for $x= 1 to 15 checks “for” condition from 1 to 15.
06:01 $r=$x*($x+1)/2 calculates the value of variable 'r'.
06:12 fontsize 18 sets the font size used by print command.
06:19 print $r displays the value of variable 'r' on the canvas.
06:26 forward 15 commands Turtle to moves 15 steps forward on the canvas.
06:34 go 10,250 commands Turtle to go 10 pixels from left of canvas and 250 pixels from top of canvas.
06:48 “Turtle” displays all print commands without any time gap.
06:54 “Wait 2” command makes Turtle to “wait” for 2 seconds before executing next command.
07:04 “print” command displays the string within double quotes and also displays variable '$r'.
07:13 Let me click on the “ Run” button to run the program.
07:17 A series of sum of first 15 natural numbers and "Sum of first 15 natural numbers" are displayed on the canvas.
07:27 Turtle moves 15 steps forward on the canvas.
07:32 With this, we come to the end of this tutorial.
07:37 Let us summarize.
07:40 In this tutorial we have learned to use
07:44 “while”' loop and “for” loop.
07:47 As an assignment, I would like you to write programs to evaluate-
07:54 * Multiples of 2 using “while” loop.
07:58 *Multiplication table of a number using “for” loop.
08:03 Watch the video available at this URL:

http://spoken-tutorial.org/What_is_a_Spoken-Tutorial

08:08 It summarizes the Spoken Tutorial project.
08:12 If you do not have good bandwidth, you can download and watch it.
08:17 The Spoken Tutorial Project team:
08:20 * Conducts workshops using spoken tutorials.
08:23 * Gives certificates to those who pass an online test.
08:27 For more details, please write to:
