C# Variables,How to declare in C#:

What is C# Variables how to declare in C#:



C# Variables:

Available is a name given to a storage area (memory) that our programs can manipulate. Each variable in C# has a specific type( variable type, or you can say data type), which determines the size and layout of the variable in  memory; the range of values that can be stored within that memory.
We have already discussed various data types. The basic value types provided in C# can be categorized as:

C# Variable Type :

  • Integral types :-Sbyte, byte, short, ushort, int, uint, long, ulong and char
  • Floating point types:-  Float and double
  • Decimal types :- Decimal
  • Boolean types :- True or false values, as assigned
  • Nullable types :- Nullable data types

C# also allows defining (declare) other value types of variable like reference types of variables and enum type. reference types  like class.
Variable Definition or declare in C# language:

 C# Variables

Syntax in C# Variable is:

<data_type> <variable_list>;
Here, data_type must be a valid C# data type including char, float, double,int,  or any user-defined  etc.and variable_list may consist of one or more  names separated by commas.


Some valid C# variable Example are  here:

char c, ch;
int i, j, k;
float f, salary;
double d;

Variable Initialization in C# :

Variable initialize means assigned a value to variable with an equal sign. The general form of initialization is.

variable_name = value;

Variables can be initialized in time of their declaration. The initializer consists of an equal sign.
<data_type> <variable_name> = value;

Some examples  of variable initialization are:

int d = 3, f = 5;
byte z = 22;
double pi = 3.14159;
char x = 'x'; 

Examples  of variable initialization in C# :

 class Program
 {
 static void Main(string[] args)
 {
 short a;
 int b ;
 double c;
 /* actual initialization */
 a = 10;
 b = 20;
 c = a + b;
 Console.WriteLine("a = {0}, b = {1}, c = {2}", a, b, c);
 Console.ReadLine();
 }
