Variable in C#

What is a variable in C#?

 In C#, a variable is a named memory location that is used to store data of a specific type. Variables are used to store values that can be manipulated and used throughout the program. 

When you declare a variable in C#, you must specify its data type, which determines the range of values it can hold, the operations that can be performed on it, and the amount of memory that will be allocated to it. Some of the built-in data types in C# include int, double, char, bool, and string.

Here's an example of declaring a variable in C#:

int age; // declares a variable named age of type int

Once you've declared a variable, you can assign a value to it using the assignment operator "=":

age = 30; // assigns the value 30 to the age variable

You can also declare and assign a value to a variable in one step:

int age = 30; // declares and assigns the value 30 to the age variable

Variables can be used throughout your C# program to store and manipulate data, and their values can be changed as needed during the execution of the program.
