Name of variables

Variable names must follow rules, such as no spaces.

After deciding on a type, the programmer must select a good name for the variable.

A variable name must start with a letter of the alphabet or an underscore.

After the first letter, there can be additional letters, digits and underscores.

There cannot be any spaces in a variable name.

Words that have a special meaning such as Do or Boolean should not be used to name variables.

The name of the variable should indicate its purpose. Variable names like a, b and c are not
very good names for variables unless you are using them for the three sides of a triangle.

If two words are joined together (you can’t have any spaces), a capital letter for the second
word or an underscore can improve the clarity. Example: hoursWorked.
