|00.02
| Welcome to the spoken tutorial on '''Arithmetic Operators in C ''''''C++'''.

|-
| 00.08
| In this tutorial, we will learn about

|-
| 00.10
|Arithmetic operators like

+ Addition: eg. a+b.

- Subtraction: eg. a-b.

/ Division: eg. a/b.

* Multiplication: eg. a*b.

% Modulus: eg. a%b.

|-
| 00.28
| To record this tutorial, I am using:'''Ubuntu 11.10''' as the operating system

|-
| 00.33
|'''gcc''' and '''g++ Compiler version 4.6.1 in Ubuntu'''.

|-
|00.39
| I will now demonstrate the use of these arithmetic operations with the help of a '''C''' program.

|-
| 00.45
| I have already written the program.

|-
| 00.47
|So I will open the editor and explain the code.

|-
| 00.50
| Here is the C program for arithmetic operators.

|-
| 00.57
| the first two statements the variables are declared and defined.

|-
| 01.03
|In the next two statements,

|-
| 01.05
|'''a''' is assigned the value of 5.

|-
| 01.07
|'''b''' is assigned the value of 2.

|-
| 01.11
| Now let's see how the addition operator works.

|-
| 01.15
|'''c''' holds the sum of '''a''' and '''b'''.

|-
| 01.19
| This '''printf''' statement displays the sum of a and b on the screen.

|-
| 01.29
|Here %.2f provides the precision of two digits after the decimal point.

|-
| 01.37
| In the next statement, '''c''' holds the product of '''a''' and '''b'''.

|-
| 01.43
| This '''printf''' statement displays the product of a and b on the screen.

|-
| 01.49
|Let's see how these two operators work.

|-
| 01.53
| We will comment out the following lines

|-
| 01.56
|Type '''/*''' '' */ ''

|-
| 02.05
| Click on '''Save''

|-
| 02.08
|Save the file with extension '''.c'''

|-
| 02.11
|I have saved the file as''' arithmetic.c'''

|-
| 02.15
| Open the terminal window by pressing '''Ctrl, Alt and T '''keys''' '''simultaneously.

|-
| 02.23
| compile the code, type the following on the terminal.

|-
| 02.27
|'''gcc arithmetic.c -o arith'''

|-
| 02.38
|'''Press Enter'''

|-
| 02.41
|To execute the code, type '''./arith'''

|-
| 02.48
| press '''Enter'''

|-
| 0250
| The output is displayed on the screen.

|-
| 02.53
|It shows,

|-
| 02.54
|Sum of 5 and 2 is 7.00 and

|-
| 02.59
|Product of 5and 2 is 10.00

|-
| 03.05
| Now you should try the subtraction operator on your own

|-
| 03.09
|Try replacing the addition operator with subtraction operator.

|-
| 03.14
|You should get the result as 3.

|-
| 03.19
| Coming back to the program and the last set of statements.

|-
| 03.23
|Now, I will explain the code for division.

|-
| 03.26
|Remove the multi line comments from here and here.

|-
| 03.35
| In these statements, '''c''' holds the value of integer division of '''a''' by '''b'''.

|-
| 03.41
|Please note that in integer division the fractional part is truncated.

|-
| 03.47
| The '''printf '''statement displays the division output on the screen.

|-
| 03.58
| In this statement we are performing real division.

|-
| 04.02
|Here one of the operands has to be cast as '''float'''
|
|-
|04.10
| We have type-cast variable a.
|-
| 04.14
|Now a will behave as a float varible for a single operation.

|-
| 04.24
|The printf statement displays the output of real division on the screen.

|-
|04.31
| Type '''return 0''' and close the ending curly bracket.

|-
| 04.37
| Click on '''Save.'''

|-
| 04.40
| Coming back to the terminal to compile and execute the code.

|-
| 04.45
| | To compile, type'''gcc arithmetic.c -o arith'''. Press Enter

|-
| 04.59
|To execute the code, type '''./arith'''Press Enter

|-
| 05.05
| The output is displayed on the screen:

|-
| 05.08
|We have the previous outputs of addition and multiplication operators.
|-
| 05.17
|we have the integer Division of 5 by 2 is 2.

|-
|05.22
|We can see that in integer division fractional part is truncated.

|-
| 05.29
|then we have the real division of 5 by 2 is 2.50.

|-
| 05.35
|In real division the result is as expected.

|-
| 05.38
|We used type-casting to obtain these result.

|-
| 05.45
| Now suppose, I want to write the same program in C++.

|-
| 05.50
|Let see if i can use the same code in C++, too?

|-
| 05.55
| Let's find out.

|-
| 05.56
|Let me go back to the editor.

|-
| 06.01
| Here is a C++ code.

|-
| 06.05
| Notice that the header is different from the C file header.

|-
| 06.13
|'''namespace''' is also used here.

|-
| 06.19
| Also, notice that the output statement in C++ is '''cout'''.

|-
| 06.25
| So, apart from these differences, the two codes are very similar.

|-
| 06.32
| Click on '''Save'''.

|-
| 06.33
|Make sure the file is saved with the extension '''.cpp'''

|-
| 06.37
|I have saved my file as''' arithmetic.cpp'''

|-
| 06.42
| Let's execute the code and seewhat results we get.

|-
| 06.49
|Open the terminal and type '''g++ arithmetic.cpp -o arith'' .'''Press Enter'''

|-
| 07.09
| To execute the code Type '''./ arith'''Press Enter'''

|-
| 07.17
| Here the output is displayed:

|-
| 07.19
|So, we see that the results are similar to C program.

|-
| 07.23
|The only difference is in the precisions of outputs.

|-
| 07.30
| Let us now summarize the tutorial.

|-
| 07.32
|In this tutorial we learnt how to use the arithmetic operators.

|-
| 07.37
| As an assignment:

|-
| 07.38
|Write a program to demonstrate the use of modulus operator.

|-
| 07.43
|Please note that Modulus operator finds the remainder of division. eg. c = a % b;

|-
| 07.51
|You should obtain the result as 1.
