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 '#' hyash 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 "clear" command 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 '#' hyash 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'.
