Time Narration
00:01 Welcome to the spoken-tutorial on Structures in C and C++.
00:06 In this tutorial we will learn,
00:08 What is a Structure.
00:10 Declaration of a structure.
00:13 We will do this through an example.
00:15 To record this tutorial, I am using
00:18 Ubuntu Operating System version 11.10,
00:22 gcc and g++ Compiler version 4.6.1.
00:28 Let us start with an introduction to Structure .
00:31 When one or more variables are grouped under one name, it is known as structure.
00:37 Structure is used to group different data into one object.
00:42 It is called as compound data-type.
00:45 It is used to group related information together.
00:49 Now we will see the syntax to declare a structure.
00:52 Here, the keyword struct tells the compiler that a structure is declared.
00:59 strcut_name is the name of the structure.
01:02 eg. struct employee;
01:04 You can give any name.
01:07 Now we will see how to declare a structure variable.
01:10 The syntax for this is:
01:13 struct struct_name and struct_var;
01:17 struct_var is the variable of type struc_name.
01:21 example, struct employee addr;
01:26 addr is the variable of type employee.
01:30 Let us move on to our example.
01:33 I have already typed the program on the editor. So, let me open it.
01:37 Note that our file name is structure.c.
01:41 In this program we will calculate the total marks of three subjects using structure.
01:48 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.
02:03 Variables defined under the structure are called as members of the structure.
02:09 This is our main() function.
02:11 Here we have declared an integer variable 'total'.
02:16 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.
02:28 Here we have modified the members
02:31 by assigning them values as 75, 70 and 65.
02:37 Here we calculate the total of three subjects.
02:41 Then we print the result.
02:44 This is our return statement.
02:46 Now click on Save .
02:48 Let us execute the program.
02:50 Please open the terminal window by pressing
02:54 Ctrl, Alt and T keys simultaneously on your keyboard.
02:59 To compile, type gcc space structure.c space hyphen o space struct and press Enter.
03:12 To execute, type (dot slash)./struct. Press Enter.
03:17 The output is displayed as:
03:20 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.
03:30 First press Shift, Ctrl and S keys simultaneously on the keyboard.
03:37 Now save the file with an extension .cpp
03:41 and click on save.
03:43 Let's change the header file as iostream.
03:47 Now include the using statement
03:53 and click on save.
03:56 Structure declaration in C++ is same as in C.
04:01 So, no need to change anything here.
04:05 At the end we will replace the printf statement with the cout statement.
04:12 Delete the format specifier and (backslash n) \n.
04:15 Now delete the comma.
04:17 Type two opening angle brackets.
04:20 Here, delete the closing bracket
04:22 and type two opening angle brackets.
04:25 And within the double quotes, type \n (backslash 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 hyphen o space struct1 .
04:46 Here we have struct1 because we don't want to overwrite the output parameters struct for the file structure.c .
04:55 Now press Enter.
04:57 To execute, type (dot slash) ./struct1. Press Enter.
05:03 The output is displayed as:
05:05 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.
05:14 We will summarize now. In this tutorial we learned,
05:18 Structure, Syntax of a structure
05:20 eg. struct struct_name;
05:23 To access members of a structure.
05:25 Eg: stud.maths = 75;
05:30 And to add the structure variables.
05:33 Eg: total = stud.eng + stud.maths + stud.science;
05:40 As an assignment, write a program to display records of an employee.
05:44 Like name, address, designation, and salary.
