What are the different types of data types used in c.net?

Answer 1

In C#, data types can be categorised as

1. Value Types.
2. Reference Types.

Value Types

Variables defined from Value Types store values. Copying one value type caribale tp another, doesn't affect the priginal vraible.

They can be further categorised into: -

1) structs: - They can be numeric (int, float, decimal), bool, user-defined structs.

2) Enumerations: - They consist of a set of named constants. By default the first enumerator has value=0.

Reference Types

These objects store references to the actual data. These can be categorised into: -

1) Classes: -- They encapsulate data and its functionality into a single entity called OBJECT.

2) Interfaces: - These are used to declare the signatures, blurprints of methods, delegates and events.

3) Delegates: - These contain the addresses/references to a method.

Answer 3

there are three data type ic c language. they are,

1.primary data type:

a.integer type

b.floating point type

c.character type

d.void type

2.derived data type

eg; array, pointer

3.userdefined data type

eg; structer and union

Answer 4

Primitive C++ data types:

unsigned short int

short int

unsigned long int

long int

int

unsigned int

char

wchar_t

bool

float

double

long double

All other types, including struct and class types, are user-defined types, some of which are provided by your IDE and third-parties, all of which are based upon some combination of the above primitives.

Answer 5

Fundamental types in C:

• Boolean type (bool)
• Character types (char)
• Integer types (int)
• Floating-point types (float, double)
• A type to signify the absence of information (void)

From these we can construct other types:

• Pointer types (such as int*)
• Array types (such as char[])

In addition, a user can define additional types:

• Data structures
• Enumerations

The boolean, character and integer types are collectively known as the integral types.

The integral and floating-point types are collectively known as the arithmetic types.

The fundamental types and pointers are collectively known as the built-in types.

Enumerations and structures are collectively known as user-defined types.

Arrays can be constructed from user-defined types as well as built-in types.

The short, long, signed and unsigned types are actually modifiers rather than types. However, if a type is not specified, the int type is assumed (a long is really a long int). The signed and unsigned modifiers can also be applied to char types. The long modifier can also be applied to the double type.

All other built-in types (such as wchar_t, size_t, ptrdiff_t, and so on) are merely aliases for existing built-in types. For instance, size_t is typically defined as being an alias for unsigned short int.

Answer 6

Same as c language.there are 3 types of data types.they INT,CHAR,FLOAT.

hey double is also a basic data type in C++
