Title of script: Ruby Methods

Keywords: method,method syntax, return, video tutorial
Visual Cue | Narration |
Slide 1 | Welcome to the Spoken Tutorial on Ruby Methods. |
Slide 2
Learning Objective |
In this tutorial we will learn
|
Slide 3
System Requirement |
Here we are using
|
Slide 4
Pre-requisites |
To follow this tutorial you must have knowledge of using Terminal and Text editor in Linux. |
Slide 5
What is Methods |
Let us now start with an introduction to methods.
A Method is a self-contained program executing a specific task. Ruby method is very similar to functions in any other programming language. |
Slide 6
Method |
Method name should begin with a lowercase letter.
Methods should be defined before calling them. |
Slide 7
Syntax for Method |
Let us see the syntax for Method
def method_name(arguments) ruby code end OR def method_name () ruby code end
The arguments specify values that are passed to the method, to be processed. The ruby code section represents the body of the method that performs the processing. The method body is enclosed by this definition on the top and the word end at the bottom. This is called as method with arguments. |
Slide 7 | Another syntax for method is
The keyword def followed by the method name and an empty argument list.
And the word end that marks end of method This is called as method without arguments. |
Switch to the editor – gedit. | Let's see how to use a method.
I have already typed a program in the gedit editor. Let me open it. |
Point to the filename on the Title bar. | Please note that our filename is method-without-argument.rb
I have saved the file inside the rubyprogram folder. |
In this program we will calculate the sum of two numbers using method. | |
Let us go through the program. | |
Highlight $a=5 | Here we have declared a global variable a.
And we have initialized it by assigning value of 5. Global variable names are prefixed with a dollar sign ($). |
Global variables are accessible from anywhere in the Ruby program;
regardless of where they are declared. | |
Highlight def add() | Here we have declared a method called add without any arguments. |
Highlight print"Enter the second number:" | Here we ask the user to enter the second number. |
Highlight b=gets.to_i | User will enter the value. |
Highlight gets | gets method gets the input from the console but in a string format. |
Highlight to_i | So we need to convert it into integer, using to_i method. |
Highlight b | The converted value is then stored in the variable b .
b is a local variable. It is available only to the method inside which it is declared. |
Highlight sum=$a+b | Here we add the values of global variable a and variable b.
The result is then stored in variable sum. |
Highlight puts"Sum of#{ $a} & #{b} is #{sum}" | Then we print the sum. |
Highlight #{sum} | This shows a way of inserting a variable within a string.
Here the content of sum is returned as a string and is substituted into the outer string. |
Highlight end | end marks end of the method. |
There are two types of methods.
User-defined method - that is our add method. Pre-defined method - that is print, gets and to_i method. | |
Highlight add() | Here we call the add method.
The addition operation will be performed and the result will be printed. |
Click on Save. | Now let us click on Save.
This program will be saved in rubyprogram folder as mentioned earlier. Now let us execute the program. |
Press Ctrl+Alt+t
Switch to Terminal |
Open the terminal by pressing the Ctrl, Alt and T keys simultaneously.
A terminal window appears on your screen. |
To execute the program, we need to go to the subdirectory rubyprogram. | |
Type cd Desktop/rubyprogram<< Press Enter | So let's type cd space Desktop/rubyprogram and press Enter. |
Now Type ruby method-without-argument.rb <<Press Enter | Type ruby space method-without-argument.rb and press Enter |
Enter the second number is displayed.
I will enter value as 4. Type 4 and press Enter | |
Highlight Sum of two numbers 5 and 4 is 9 | We get the output as -
Sum of two numbers 5 and 4 is 9 |
Switch back to editor | Now let us see an example of method with arguments.
I have already typed this program in the gedit editor, let me open it. |
Point to the filename in the Title bar. | Please note that our filename is method-with-argument.rb
I have saved this file also inside the rubyprogram folder. |
Let us go through the program. | |
Highlight def add(a ,b) | Here we have declared a method called add.
a,b are the arguments of the method add. |
Highlight return a+b | Here the values of a and b are added.
And the sum is returned to the method call. |
Highlight end | end marks the end of method. |
Highlight puts"Enter the values of a and b"
a=gets.to_i b=gets.to_i |
Here we are asking the user for input.
User will enter the values of a and b. The values will be stored in variable a and variable b, respectively. |
Highlight c=add(a,b) | Here we call the add method
Then we pass the arguments as a and b. |
Highlight c | The value returned by the method add ,after performing the addition operation will be stored in c. |
Highlight puts"Sum of two number #{a} and #{b} is #{c}" | Here we print the sum which is store in c. |
Switch back to terminal
Type clear<<Press Enter |
Let's execute this code.
Go to the terminal. Let us first clear the terminal Type clear and press Enter |
Point to the command prompt to show subdirectory rubyprogram | We are already in the subdirectory rubyprogram. |
Replace
ruby method-with-argument.rb << Press Enter |
Now, press the up arrow key twice to get the previous command.
Replace method-without-arguments.rb with method-with-arguments.rb And Press Enter |
Enter the values of a and b is displayed.
I will enter 8 and 9. Type 8 and press Enter Type 9 and press Enter | |
Highlight Sum of two numbers 8 and 9 is 17 | We get the output as
Sum of two numbers 8 and 9 is 17. <<pause>> |
Now I will show you one important feature of Ruby method. | |
Switch back to the text editor | Let's go back to the program in the text editor. |
Delete the keyword return. | |
Click on Save | Now click on Save button. |
Switch back to terminal | Let's execute the code.
Go to the terminal. |
Replace
ruby method-with-argument.rb << Press Enter |
Press the up arrow key to get the previous command and
Press Enter. |
Enter the values of a and b is displayed.
I will enter 10 and 15. Type 10 and press Enter Type 15 and press Enter | |
Highlight Sum of two numbers 10 and 15 is 25 | We get the output as
Sum of two numbers10 and 15 is 25. |
We can see that the program is executed without any error, even after deleting the keyword return. | |
Switch back to the program
Highlight a+b |
This is because Ruby automatically returns the value calculated in the method.
The keyword return in method is optional in Ruby. |
<<Pause>>
This brings us to the end of this Spoken Tutorial. | |
