QUESTION 4:
What (do you suppose) the following does?
LET DAY$(1) = "Monday" PRINT "The day is", DAY$(1)
(Don't run this program yet. It needs more work.)
No. The item numbers start at one and go up to some maximum number.
(In the real world, aquisition numbers do not necessarily follow in sequence, but let us do that here.)
In programming, when you have a collection of similar items, each with an item number, the collection is called an array, and the item number is called a subscript.
To refer to a specific item in an array do this:
arrayName( subscript )
The name of the array is followed by the item number (the subscript) inside of parentheses.
For example,
say that DAY$ is an array of
strings—one for each day of the week.
Then,
LET DAY$(1) = "Monday"
makes "Monday" the first string of the array:
DAY$ is the name of the array (the collection of items).(1) selects item number 1.What (do you suppose) the following does?
LET DAY$(1) = "Monday" PRINT "The day is", DAY$(1)
