What Is .NET (DOT NET) ?

What is .NET ?

Before start to learning c# we must be aware about the term .net (dot net). In general speaking , we listens about .net. 

In this tutorial we are going to learn what .net is and what is the relation between the .net and C#. So let’s see-

Microsoft doesn’t provide any description of the word .net (dot net). Actually .net is a framework that contains set of classes and various programming languages.

In short we can say that .net (dot net) is a tool by using which we can develop various desktop applications, web applications, web services, mobile applications etc.

Dot net (.net) contains 30+ programming languages such as c#,VB,J#,F# etc.

Means C# is one of the programming languages of the .net (dot net). C# is a major programming language which is most popular language among all other .net (dot net) programming languages.

For the development of applications .net (dot net) provide visual studio IDE. IDE stands for the Integrated Development environment. It is Microsoft tool by using which you can develop applications in .net. You can also third party IDE’s.

We can develop desktop applications by using .net programming languages like,, etc.

For development of web applications .net provides a technology called ASP.NET

In short we will see what is desktop applications and web applications

Desktop applications :

Desktop applications are nothing but the applications which have extensions .exe. these applcations can be executed directly.

They can be install on the any computer or a laptop.and they can run independently.

Some examples of desktop applications are word,excel,powerpoint,clock, calendar etc.

Web applications:

Web applications are nothing but the applications which are based on the network and they are accessed by using the web browers. 

Web applications are hosted on the server and it is accessed by the clients with the help of web browers.

So friends in this tutorial we have seen little about .net (dot net), and desktop and web applications. In next chapter we will introduce to the visual studio IDE.

Operators In C

Operators In C

operators in c

operators in c refers to the symbols which are used to perform mathematical operations in c programming. Operators  are nothing but the specific symbols which is used to perform mathematical operations in the program.

Programming c is very rich in operators. We can perform all type of mathematical operations in c. for that it provides wide range of c operators.

C programming provides following type of different operators-

  1. Arithmetic Operators
  2. Relational Operators
  3. Assignment Operators
  4. Logical Operators
  5. Increment and Decrement Operators               
  6. Bitwise Operators
  7. Special Operators

C Arithmetic Operators

In c arithmetic operators are used to perform basic type of mathematical operations such as addition,subtraction,multiplication ,division etc. these operators are mostly use in the programs.
Following table shows the arithmetic operators and their use with example.


C Relational Operators

Relational operators are used to  check the relation between two operands. relations such as  less than,greater than, equals to,etc. these operators are mostly used in decision making statements.

Returns true if value is smaller than comparing value
4<2     returns false
2<8     returns true
Returns true if value is bigger than comparing value
8>2     returns true
5>10   returns false
Returns true if value is less or equal  to the given value
2<=5   returns true
6<=3   returns false
5<=5   returns true
Returns true if value is greater or equal to the given value
8>=8   returns true
5>=6   returns false
10>=6  returns true
Returns true if two values are same
10==10 returns true
6==5     returns false
Returns true if given value is not equal to comparing value
10!=10  returns false
10!=50 returns true

Assignment Operator

Assignment operators are used to assign values to the variables. Following table shows the various assignment operators in c.

a = b
a = b
a += b
a = a+b
a -= b
a = a-b
a *= b
a = a*b
a /= b
a = a/b
a %= b
a = a%b
C <<= 2
is same as C = C << 2
C >>= 2
is same as C = C >> 2
C &= 2
is same as C = C & 2
. C ^= 2
is same as C = C ^ 2
C |= 2
is same as C = C | 2

Increment and decrement operators

Increment and decrement operators are used to increase and decrease value of variables by 1 respectivly. following table shows details about increment and decrement operators.

Increase value of variable by one
Decrease value of variables by one

Logical operators

Logical operators are used to check the conditions. It returns  0 or 1 depending upon condition become true or false. Suppose a=0 and b=1

It returns true if given all conditions are become true
(a && b) is false.
It returns true if any one condition becomes true
(a || b) is true.
It converts true to false and false to true
!(a && b) is true

Bitwise operator

Bitwise operators works on bit level. They perform calculations on bit level. Following table shows the detail information about bit level operators.

Bitwise AND
Bitwise OR
Bitwise exclusive OR
Bitwise complement
Shift left
Shift right

specail operators

Following are some important operators which are very important in c. they are used for different purposes these operators shown in following table.

Returns the size of a variable.
sizeof(i), where i is integer, will return 4.
Returns the memory address of a variable.
&b; returns the actual address of the variable.
Pointer to a variable.
? :
Conditional Expression.
If Condition is true then it returns first value otherwise second value  will be return
