Arrays are used to hold data as
an array of variables, which can be accessed with their index number.
A String is also an array of
characters. However in asp or such high level language we can
add/concatenate and search through strings or apply other type of
functionality on them very easily.
Arrays and string.
The first example defines an array
named myArray and put three value in it. The for loop display them
one by one.
In the second example split
function is used to breakdown a string into array of words. The
split function cuts down a string into words by considering a space
" " as a delimiter, any other character or string can also be used
as a delimiter . The split function is a very handy function while
programming.
The third example is showing how to
add two string and other useful string manipulation stuff.
<%
'Example 1
Dim myArray(4) ' Dynamic array of any number of elements.
myArray(0) = "Sunday"
myArray(1) = "Monday"
myArray(2) = "Tuesday"
For i=0 to 2
response.write i & ")" & myArray(i) & "<br>"
Next
%>
<hr>
<%
'Example 2
myText="Hello My World!"
myArray2=Split(myText, " ")
response.write myArray2(0) & "<br>"
response.write myArray2(2) & "<br>"
%>
<hr>
<%
'Example 3
Dim strOne, strTwo
strOne = "Hello,"
strTwo = "How are you."
strThree= strOne & strTwo
Response.write strThree & "<hr>"
'Len() function returns length of string.
Response.write "Length of first String is:" & Len(strOne)
Response.write "<hr>"
'Asc() returns the ascii value of a character
Response.write "Ascii value of A is:" & Asc("a")
Response.write "<hr>"
'Instr() returns the location of first occurance of a string
within the input string. Returns 0 if its not found.
Response.write "Location of 'are' in strTwo:" &
Instr(strTwo,"are")
