A variable is just a storage for data of values in the program. In programming world, every variables has a datatype and in most programming language, C# included, a variable's datatype is determined when the variable is declared or initialized. There are several ways to declare a variable:

• [data type] [identifier];
• [data type] [identifier] = [value];
• [data type] [identifier 1], [identifier 2], [identifier N];
• [data type] [identifier 1] = [value 1], [identifier 2] = [value 2], [identifier N] = [value N];
• 
  

For example:

• int totalItemCount;
• string customerName = Fandi;
• double price1, price2, price3;
• int amount1 = 10, amount2 = 7, amount3 = 12;
• 
  

The first and third example above only declare variables, they don't assign any value to the variables. An empty variable must be assigned a value before being read. If an empty variable is read, a runtime error will occur. While the second and fourth example have already assigned values to the variables so that the variables are ready to be read. If a variable is empty when being read, a runtime error will occur.

The datatypes used above are the most common datatype used, int is an integer, string is a collection of characters, and double is a real number. We will learn about datatypes in the next part of this tutorial.
