What types of variables are included in the C# language and what are their characteristics?

Supported value types in C# include integers, floating point, Boolean, characters, and enumeration types; reference types include classes, interfaces, arrays, and strings. Value types are stored on the stack, and when copied, a copy is created, while reference types are stored on the heap, and when copied, another reference to the original data is created.

Variable Types in C

#In C#, variables are used to store data. The following are the different types of variables supported by C#:

Value type

• ##Integer type: byte, sbyte, short , ushort, int, uint, long, ulong

  stores integers and numbers within a specific range.

• Floating point types: float, double

  Storage decimals and larger number ranges.

• Boolean type: bool

  Stores a Boolean value (true or false).

• Character type: char

  Stores a single character.

• Enumeration type: enum

  A constant that defines a set of related values.

Reference type

• Class: A blueprint for a specific object, containing its data and methods .
• Interface: Defines the methods that an object must implement.
• Array: Stores a collection of elements of the same type.
• String: Stores text characters.

Type characteristics

Value type:

Stored on the stack.
• Create a new copy when copying. When
• is modified, the original value will not be affected.

Reference type:

Stored on the heap.
• The reference variable points to the actual data on the heap.
• Copying a reference variable does not copy the data, but creates another reference to the original data. When
• is modified, it will also affect the original data.
