CSharp Variables

What are variables in general

In any programming language, a variable refers to a space in the computers memory. We give this space a meaningful name so that we can refer to that memory in our code easily without causing any confusion. 

Assigning a value to a variable means that we intend to put a value in the memory identified by the variable.

How to declare variables in C#

The syntax in C# to declare a variable is to first write the type and then its name like so:


typeOfVariable nameOfVariable;

            int counter;
            string name;
            double price;

Declare and Assign a value at the same time

You can declare and assign the value to a variable in a signle step like so:

typeOfVariable nameOfVariable = thevalueofthevariable;

These are some good examples of variable declarations with value assignment.

            int counter = 0;

            string name = "Your Name";

            double price = 24.99d;

These are some bad examples of variable as their names do seem to be meaningful:

            int x = 0;

            string theVariable = "Your Name";

            double p = 24.99d;
