Simple and Easy Explaination about C# Data Types

In this article i will try to explain Data Types,Type and Data Types in easy and simple words.

What is Data Type :

Data Type is nothing but storing the values in a particular variable and that variable describe the type of the value. The value can be any form like Numeric Value, Floating Values, Boolean Values, Char and String Values and so on.

Types of Data Type :

1. Numerical Data Types
2. Floating Point Data Types
3. Character Related Data Type
4. Logical Data Types
5. General Data Types

1. Numerical Data Types

Numerical Data Types will be 2 types

• Signed Numerical Data Type
• Unsigned Numerical Data Type

Signed Numerical Data Type

Signed Numerical data type contain only Positive and Negative Values and its classified into 4 types.

1. sbyte

   s-stand for signed

   sbyte predefined size is 1 byte = 1*8 = 8 bits

   base type of sbyte : System.SByte

   sbyte accomodiate the memory min size : -128 and max size : 127

2. short

   s-stand for signed

   short predefined size is 2 byte = 2*8 = 16 bits

   base type of short : System.Int16

   short accomodiate the memory min size : -32768 and max size : 32767

3. int

   int predefined size is 4 byte = 4*8 = 32 bits

   base type of int : System.Int32

   int accomodiate the memory min size : -2147483648 and max size : 2147483647

4. long

   long predefined size is 8 byte = 8*8 = 64 bits

   base type of long : System.Int64

   long accomodiate the memory min size : -9223372036854775808 and max size : 9223372036854775807

Unsigned Numerical Data Type

Unsigned Numerical data type contain only Positive Values only and its classified into 4 types.

1. byte

   byte predefined size is 1 byte = 1*8 = 8 bits

   base type of byte : System.Byte

   byte accomodiate the memory min size : 0 and max size : 255

2. ushort

   u-stand for unsigned

   ushort predefined size is 2 byte = 2*8 = 16 bits

   base type of ushort : System.UInt16

   ushort accomodiate the memory min size : 0 and max size : 65535

3. uint

   uint predefined size is 4 byte = 4*8 = 32 bits

   base type of uint : System.UInt32

   uint accomodiate the memory min size : 0 and max size : 4294967295

4. ulong

   ulong predefined size is 8 byte = 8*8 = 64 bits

   base type of ulong : System.UInt64

   ulong accomodiate the memory min size : 0 and max size : 18446744073709551615

Q.) Difference between Signed and UnSigned Numerical Data Types

→ Signed Numerical Data Type contain only Positive and Negitive values

→ UnSigned Numerical Data Type contain only Positive values only

2. Floating Point Data Types

→ A number which is having fraction part is called Floating Point Data Type

→ By default Floating Point Data Types are Signed

→ we do not have any Unsigned Floating Point Data Types

→ According to the size floating point data types are classified into 3 types

1. float

   float predefined size is 4 byte = 4*8 = 32 bits

   base type of float : System.Single

2. double

   double predefined size is 8 byte = 8*8 = 64 bits

   base type of double : System.Double

3. decimal

   decimal predefined size is 16 byte = 16*8 = 128 bits

   base type of decimal : System.Decimal

3. Char Data Type

1. char

   char predefined size is 2 byte = 2*8 = 16 bits

   base type of char : System.Char

4. Logical Data Type

1. bool

   bool predefined size is 1 bits

   base type of bool : System.Boolean

   true will be stored into memory as binary 1

   false will be stored into memory as binary 0

5. General Data Type

1. string

   general data type will not have predefined size

   base type of string : System.String

2. object

   base type of object : System.Object
