variable types in c# code example

Example 1: c# data types

Type	|	Represents 							|	Range							|	Default Value
bool		Boolean value							True or False						False
byte		8-bit unsigned integer					0 to 255							0
char		16-bit Unicode character				U +0000 to U +ffff					'\0'
decimal		128-bit precise decimal values 			(-7.9 x 1028 to 7.9 x 1028) 		0.0M
			with 28-29 significant digits			/ 100 to 28
double		64-bit double-precision floating 		(+/-)5.0 x 10-324 					0.0D
			point type								to (+/-)1.7 x 10308
float		32-bit single-precision floating 		-3.4 x 1038 to + 3.4 x 1038			0.0F
  			point type
int			32-bit signed integer type				-2,147,483,648 to 2,147,483,647		0
long		64-bit signed integer type				-9,223,372,036,854,775,808 			0L
  													to 9,223,372,036,854,775,807
sbyte		8-bit signed integer type				-128 to 127							0
short		16-bit signed integer type				-32,768 to 32,767					0
uint		32-bit unsigned integer type			0 to 4,294,967,295					0
ulong		64-bit unsigned integer type			0 to 18,446,744,073,709,551,615		0
ushort		16-bit unsigned integer type			0 to 65,535							0

Example 2: c# change variable types

// Ask user for fave number
Console.Write("Enter your favorite number!: ");
int faveNumber = Convert.ToInt32(Console.ReadLine());

// Turn that answer into an int

Example 3: c# data types

// -------DATA TYPES ------- //

sbyte myNum = 1;             // Smallest range of integer numbers
uint myNum = 3;				 // Only positive integer numbers
short myNum = 4;             // Short range of integer numbers
int myNum = 5;               // Integer (whole numbers)
long myNum = 10;             // Biggest range of integer numbers 
float myFloat = 1.2f;        // Smallest range of floating point numbers
double myDoubleNum = 5.99;   // Big range of floating point numbers
decimal myDecimalNum = 2.2M; // Biggest precision in floating point numbers
char myLetter = 'D';         // Character
string myString = "Hello!"   // Strings
bool myBool = true;          // Boolean

Example 4: c# value types

// ---------------- Value Type vs Reference Type ----------------------//

// Data types are separated into value types and reference types. 
// Value types are either stack-allocated or allocated inline in a structure. 
// Reference types are heap-allocated. Both reference and value types are 
// derived from the ultimate base class Object

// Aside from serving as the base class for value types in the .NET Framework, 
// the ValueType structure is generally not used directly in code. However, 
// it can be used as a parameter in method calls to restrict possible 
// arguments to value types instead of all objects, or to permit a method to 
// handle a number of different value types. ValueType helps prevent reference 
// types from being passed to methods.

Example 5: C# varible

public varible nameofvarible;//In Unity to esablish varible new slot should appear in the script componit and drag what element you want
