Learn C# Programming in Easy way, Step-3. Variables, Datatypes, values.

Hi, Welcome to all. My name is Abdul Yesdani. Today we are going to learn how to work with different types , what is a variable, how the values are stored in a variable and how to work with numbers.

A variable is a memory location to store a value or data. Different datatypes of variables needed to store different data. Numeric data types : int, double, float, decimal.

Variables will be declared in association with data types.

Example: int number =78;

In the above statement 'int' is datatype and number is variable , '=' is assignment operator and '78' is value assigned to the variable.

Create a new Console app in the Visual studio IDE, give a relevant name to the app. 

Type the following code in the code editor.



Run the application by pressing CTRL + F5 keys . You will get the output as shown below.



Watch the video for the same.
