Time'	Narration
00:01	Welcome to the spoken-tutorial on Structures in C and C++.
00:06	In this tutorial we will learn
00:09	what is a Structure.
00:11	Declaration of a structure
00:13	We will do this through an example
00:16	To record this tutorial, I am using,
00:19	Ubuntu Operating System version 11.10,
00:23	gcc and g++ Compiler version 4.6.1
00:29	Let us start with an introduction to Structure
00:32	When one or more variables are grouped under one name it is known as structure.
00:38	Strucutre is used to group different data into one object.
00:43	It is called as compound data-type.
00:45	It is used to group related information together.
00:49	Now we will see
00:50	The syntax to declare a structure
00:53	Here the keyword struct tells the compiler that a structure is declared
00:59	strcut_name is the name of the structure.
01:03	eg. struct employee;
01:05	You can give any name.
01:07	Now we will see how to declare a structure variable.
01:12	Syntax for this is
01:14	struct struct_name and struct_var;
01:17	struct_var is the variable of type struc_name
01:22	eg. struct employee addr;
01:27	addr is the variable of type employee.
01:31	Let us move on to our example
01:33	I have already typed the program on the editor
01:36	So let me open it.
01:38	Note that our filename is structure.c
01:42	In this program we will calculate the total marks of three subjects using structure
01:49	Let me explain the code now.
01:51	This is our header file.
01:53	Here we have declared a structure as student.
01:57	Then we have declared three integer variables as english, maths and science.
02:04	Variables defined under the structure are called as members of the structure.
02:10	This is our main function
02:12	Here we have declared an integer variable total.
02:17	Now we have declared a structure variable stud. stud is the variable of type student,it is used to access and modify the structure members
02:30	Here we have modified the members
02:32	By assigning them values as 75, 70 and 65.
02:38	Here we calculate the total of three subjects.
02:42	Then we print the result.
02:44	This is our return statement.
02:47	Now click on Save
02:49	Let us execute the program
02:51	Please open the terminal window by pressing
02:54	Ctrl, Alt and T keys simultaneously on your keyboard.
03:00	To compile
03:01	Type; gcc space structure.c space -o space struct
03:10	And press Enter
03:12	To execute
03:13	Type./struct Press Enter
03:18	The output is displayed as: Total is 210
03:22	Now we will execute the same program in C++
03:26	Come back to our program.
03:28	I will edit the same code
03:31	First press shift, cntrl and S keys simultaneously on the keyboard
03:37	Now save the file with an extension .cpp and click on save
03:44	Let us change the header file as iostream
03:48	Now include the using statement and click on save
03:57	Structure declaration in C++ is same as in C
04:02	So no need to change anything here
04:05	At the end we will replace the printf statement with the cout statement.
04:08	Delete the format specifier and \n
04:16	Now delete the comma
04:17	Type two opening angle brackets.
04:21	Here delete the closing bracket
04:23	and type two opening angle backets
04:25	And within the double quotes type \n
04:29	Now click on Save
04:31	Let us execute the program
04:33	Come back to our terminal
04:35	To compile type g++ space structure.cpp space -o space struct1
04:47	Here we have struct1 because we dont want to overwrite the output parameters for the file structure.c
04:55	Now press Enter
04:57	To execute type ./struct1
05:02	Press Enter
05:04	The output is displayed as: Total is 210
05:08	You can see that the output is same as our C code
05:12	Now let us go back to our slides.
05:15	We will summarize now. In this tutorial we learned,
05:18	Structure.
05:19	Syntax of a structure.
05:21	eg. struct struct_name;
05:24	To access members of a structure.
05:26	Eg: stud.maths = 75;
05:30	To add the structure variables.
05:33	Eg: total = stud.eng + stud.maths + stud.science;
05:40	As an assignment,
05:41	Write a program to diplay the records of an employee.
05:45	Like name, address, designation, salary.
05:49	Watch the video available at the link shown below
05:53	It summarises the Spoken Tutorial project
05:55	If you do not have good bandwidth, you can download and watch it
06:00	The Spoken Tutorial Project Team
06:02	Conducts workshops using spoken tutorials
06:05	Gives certificates to those who pass an online test
06:08	For more details, please write to contact@spoken-tutorial.org
06:15	Spoken Tutorial Project is a part of the Talk to a Teacher project
06:19	It is supported by the National Mission on Education through ICT, MHRD, Government of India
06:26	More information on this Mission is available at: http://spoken-tutorial.org\NMEICT-Intro
06:30	This is Ashwini Patil from IIT Bombay. Siginning off.
06:33	Thank You for joining
