What is Open source? What does it mean?
Open source not fully means that they are free there are many open source software’s which are paid like RHEL business edition for which you have to sell some bucks out of your pocket But the majority of open source software’s are free.
Along with this you can get the source code of all open source software’s legally for free & thus if you are a good developer you can make improvement in the source code thus making the software better & posting it to the original developer of the software & if they found it really good they may published those updates in the next release of the software & even if they can’t you can yourself use the modified version legally.
Nowadays Most of the time the companies release free versions of their software for basic home users which have limited features but if you have to buy a business version for all feature you have to pay a huge amount from your pocket, & even have to pay to upgrade or update it most of the time, What the source code of the program is not made public by these money minded companies so they have all the charge of software maintenance in their hand.
Open Source Doesn't necessarily mean Free. It just means that you can see the source code, Edit it and if you want , develop a new program from it. If you want you can choose not to give it for Free.you can set a price and sell it.
Google is the location of the source code and then you can download it via tools.
Open source means you have access to the source code of the software in question.
One can use the same source code, modify it and create software.
Open source doesn't means free software, It means the Code of the software seen by any one and if anyone knows the programming he can make changes to it.
This is the default view of "My Computer".You can see hare the icon of your hard disks. These icons are traditional icons used in Windows XP.

open=
label=
According above image write the name of you icon file and and name of your drive. Then save his file with the extension inf.
To do this follow these steps:
- Click at File | Save As

1. What are pointers?
All data of a program are stored in memory.
In memory it is referred with a Unique number called ADDRESS.
Way of accessing that address using variables is called pointers.
Operators used in pointer are
& - address operator.
* - Dereferencing operator,
Example:
int*iptr; is an integer pointer.
2. What do you mean by Type Casting?
Converting data of one data type into data of another data type is called as type casting.
Type casting can be done only between compatible data types.
While converting if the assigned data is longer it will be truncated.
Example:-
int a;
float f=10.33
a=(int)f; - 10 will be stored in a and .33 will be truncated.
3. Define Character Constant.
A constant that contains a single character.
A character constant can be an, alphabet, numeral, symbol or non-graphic character.
Any character which forms part of ASCII character SET.
A Character constant is enclosed within Single Quotes(` `)
Example:-
‘a’,’+’,’3’,’\n’
4. Define Integer Constant.
A constant that contains a whole numbers.
Must have at least one digit.
Cannot have fractional or exponential part.
Can be signed or unsigned.
Example:-
10,20,1,3000,32767.
1. Define Floating point Constant.
A constant that contains a real number.
It includes a integer portion, a decimal point, a fractional portion and an exponent.
Mandatory must have either integer part of fractional part.
Can be signed.
Example:
12.33,100.00,0.66,5.864E1.
2. Define String/String literals.
A String is a sequence of characters.
Is is terminated with an escape sequence ‘\0’ (String terminator).
A string is implemented as a single dimension character array.
Example:
char name[10]={“CHARLES”};
3. What do you mean by association?
When using operators in C / C++, it is not evaluated as it is type.
Instead it is evaluated in a different order of precedence, determined earlier
(Compare with BODMAS rule of mathematics)
This logical grouping of operators for the purpose of evalutaion is called associtation
4. Define Storage Class (or) Storage Qualifier (or) Storage Specifier.
It is a qualifier which can be prefixed with a variable declaration.
It changes the behaviour of a variable(availability or visibility).
Important Storage specifiers are
Auto
Static
Register
Extern
Example:
auto int (..)
static float f=1.56;
extern int fact;
register int r;
