|-
|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
||Eg. '''“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'''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
||# 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 is 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
