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.
