Quiz

1:	When do ColdFusion functions require hash-mark delimiters?
A1:	Just like variables, functions require hash marks when they appear between `<CFOUTPUT>` and `</CFOUTPUT>` tags. If they appear as part of a tag, such as `<CFIF` `SomeFunction(SomeVariable)>,` the marks aren't required .
2:	Are function names case-sensitive?
A2:	Function names are not case-sensitive, although it's a good idea to use ColdFusion's suggested case (such as `DollarFormat()`) to make them easy to identify in your template pages .
3:	Name two functions that might be used to trim leading or trailing spaces from a text string.
A3:	`LTrim()` strips leading spaces; `RTrim()` works on trailing spaces.
4:	Briefly describe a date/time object.
A4:	A date/time object is a special unit that may hold a month, date, and year, as well as an hour, minute, and second. It is created, manipulated, and displayed using date and time functions.
5:	In the jargon of functions, what is a token?
A5:	A token is the part of a string that appears between two delimiters. For example, if I specify that I want to use spaces as delimiters in this sentence, each word would be considered a token because it appears between spaces.
6:	What is a mask?
A6:	A mask is a bit of text that specifies how a function displays a variable. For example, using a mask such as `MM/DD/YY` with `DateFormat()` causes the date January 1, 2000 to display as `01/01/00.`
