Variables are "containers" for storing information.
Do you remember algebra from school? x=5, y=6, z=x+y
Do you remember that a letter (like x) could be used to hold a value (like 5), and that you could
use the information above to calculate the value of z to be 11?
These letters are called variables, and variables can be used to hold values (x=5) or
A variable can have a short name, like x, or a more descriptive name, like Playername.
After the declaration shown above, the variables are empty (they have no values yet).
However, you can also assign values to the variables when you declare them:
After the execution of the statements above, the variable x will hold the value 5,
and Playername will hold the value Pointing.
Note: When you assign a text value to a variable, use quotes around the value.
If you assign values to variables that have not yet been declared, the variables will
automatically be declared.
have the same effect as:
After the execution of the statements above, the variable x will still have the value of 5. The
value of x is not reset (or cleared) when you redeclare it.
