variable in c#
In the first c# program chapter, we declared a variable called "message" as shown below
For Example variable C#:-
namespace CSharpTutorials { class Program { static void Main(string[] args) { string message = "Hello World!!"; Console.WriteLine(message); } } }
The variable in C# is nothing but a name given to a data value. In the above example, message is the name of the variable that stores the string data value "Hello World!!". As the name suggests, the contents of a variable can vary, i.e., you can change the value of a variable at any time.
In C#, a variable is always defined with a data type. The following is the syntax variable declaration and initialization.
variable syntax :
<data type> <variable name>; <datatype> <variable name> = <value>;
A variable can be declared and initialized later or it can be declared and initialized at the same time. In the following example, the first statement declares a variable called "message" without assigning any value to it. In the second statement, a value is assigned to the "message" variable.
string message; // value can be assigned after it declared message = "Hello World!!";
In the following example, variable is declared and initialized (a value is assigned to it) at the same time.
Example: Variable Declaration & Initialization
string message = "Hello World!!";
