Variables

We just now wrote our first program but we will rarely output such hard-coded text. Mostly we output some data that is stored in a variable. So now let's learn about Variables.

What are Variables?

Variables are like containers containing a specific value that can be accessed anywhere in the code using the variable name. A variable name must start with a letter or an underscore( _ ) and they are case-sensitive and can only contain alpha-numeric characters and underscores. Use an equal sign ( = ) to assign a variable.
