Visual Cue Narration
00.01 Hello Everybody.
00.03 Welcome to this tutorial on Programming concepts in KTurtle.
00.08 In this tutorial, we will learn how to
00.12 Write a program in KTurtle
00.15 Use variables to store user input
00.18 Use print command to print on canvas
00.22 Comment a line
00.24 To record this tutorial, I am using,Ubuntu Linux OS Version 11.10. KTurtle version 0.8.1 beta.
00.37 We assume that you have basic working knowledge of KTurtle.
00.43 If not, for relevant tutorials, please visit our website, http://spoken-tutorial.org.
00.49 Before proceeding, we will discuss some basic information about KTurtle.
00.55 "Turtle" displayed on the canvas is called "sprite".
01.00 "Sprite" is a small image that moves around the screen.e.g. Cursor is a sprite.
01.10 "spritehide" command hides Turtle from canvas.
01.15 "spriteshow" command shows Turtle if it is hidden.
01.21 "clear" command cleans all drawings from canvas.
01.27 In KTurtle,
01.29 "$ " sign is a container of variables.
01.34 "*"(asterisk) is used for multiplication of two numbers.
01.41 "^"(caret) raises a power of the number.
01.45 "#"(hash) sign comments a line written after it.
01.50 "sqrt" is an inbuilt function to find square root of a number.
01.58 Let's open new KTurtle Application
02.02 Click on Dash home >> Media Apps.
02.07 Under Type, Choose Education and KTurtle.
02.13 KTurtle application opens.
02.20 We can also open KTurtle using terminal.
02.24 Press CTRL+ALT+T simultaneously to open the terminal.
02.30 Type KTurtle and press enter, KTurtle Application opens.
02.41 Let me type and explain the program code.
02.46 Let me zoom into the program text, it may possibly be a little blurred.
02.55 #program to find square of a number. enter টিপুন।
03.15 #program to find square of a number. Press enter
03.19 This means, this line will not be executed while running the program. Press enter.
03.29 reset
03.30 reset command sets Turtle to default position. Press enter.
03.38 $i= ask within double quotes enter a number for i and click OK.
03.58 "$i" is a variable to store user input.
04.03 “ask” command asks for user input to be stored in variable.press enter
04.11 “fontsize” space 28.
04.17 fontsize sets the font size used by print.
04.20 Fontsize takes number as input, set in pixels.
04.27 print $i*$i
04.36 print $i*$i calculates and prints square of a number. press enter.
04.45 spritehide
04.48 spritehide hides Turtle from canvas.
04.53 Let us Run the program now.
04.56 Click on the Run button on the toolbar to start execution of the code in the editor.
05.03 It shows a list of execution speeds.
05.07 Full speed(no highlighting and inspector)
05.10 Full speed,

slow, slower, slowest and step-by-step.

05.17 Let me run the code at slow speed.
05.21 An "input bar" appears
05.23 let's enter 15 for i and click OK
05.29 square of '15' = '225' is displayed on the canvas.
05.35 Let's now learn to find nth power of a number through a program.
05.42 I already have program in a text editor.
05.46 Let me copy the program from text editor and paste it into KTurtle editor.


05.56 Please pause the tutorial here and copy the program into your KTurtle editor.
06.03 Let me zoom into the program text.
06.07 Explain the program.
06.09 # sign comments a line written after it.
06.13 reset command sets Turtle to default position.
06.18 $i and $n are variables to store user input.
06.25 “ask” command asks for user input to be stored in variables.
06.31 fontsize 28 sets the font size used by print.
06.37 Fontsize takes number as input, set in pixels.
06.43 print ($i^$n) calculates & prints nth power of a number.
06.52 spritehide hides Turtle from canvas.
06.57 Let's run the program.
07.00 Let's enter '5' for i, and click OK
07.05 Let's enter '4' for n, and click OK. 5^4=625 is displayed on canvas.
07.18 Next, let's use inbuilt “sqrt” function in a program to find square root of a number.
07.27 Let me copy the code from editor and paste it into KTurtle's editor.


07.35 Please pause the tutorial here and copy the program into your KTurtle editor.
07.43 Let me zoom the program text it may possibly be a little blurred.
07.49 Let me explain the code.
07.52 # sign comments a line written after it .
07.57 reset command sets Turtle to default position.
08.02 $i is a variable to store user input.
08.07 fontsize 28 sets the font size used by print.
08.12 print sqrt $i prints square root of a number.
08.19 spritehide hides Turtle from canvas.
08.24 Let me run the program now.
08.28 Let's enter '169' for i, and click OK
08.34 square root of 169 = 13, is displayed on canvas.
08.39 Let's run again,
08.42 let's enter -169 for i and click OK.
08.49 If we enter negative number, output is 'nan' it means not a number.
08.56 As square root of negative number is not a real number.
09.02 let's next evaluate Cube root of a positive number through a program.
09.08 Let me copy the program from editor and paste it into KTurtle's editor.
09.19 Please pause the tutorial here and copy the program into your KTurtle editor.
09.25 Let me zoom into the program text it may possibly be a little blurred.
09.31 Let me explain the program.
09.35 # sign comments a line. Written after it.
09.38 Please note this is a single line comment.
09.42 Every comment must be preceeded by a # sign.
09.48 reset command sets the Turtle to default position.
09.53 $i and $C are variables to store user input.
09.59 $C=($i)^(1/3) calculates cube root of a number.
10.07 fontsize 28 sets the font size used by print.
10.13 print $C prints cube root of a number.
10.19 spritehide hides Turtle from canvas.
10.23 Let's Run the program
10.27 Let's enter 343 for i and click OK
10.34 cube root of 343 = 7 is be displayed on canvas.
10.40 With this we come to the end of this tutorial.
10.43 let us summarize.
10.46 In this tutorial, we have learnt
10.49 Programming concepts
10.52 Use of sqrt function
10.55 Use of print command
10.57 Using KTurtle editor and canvas.
11.02 As an assignment, I would like you to use basic programming commands to find ...
