Arrays are indexed. So to look at the 4th element of an array, you'd do:
Example 4-7. Accessing elements in an array
string *colors = ({ "red", "blue", "green", "yellow", "black" });
string fourth_color = colors[3]; // fourth_color here will be "yellow"
Remember that array indexes are 0-based. The first element is index 0, the second element is index 1, the third is index 2, the fourth is index 3.
LPC has a range operator "..". This allows you to access a range of an array. In Python, this is called a slice. Some languages call it a subarray.
Example 4-8. Using the range operator on arrays
string *names = ({ "joe", "jeff", "jack", "harry" });
string *somenames = names[0..2];
The variable somenames will be ({"joe", "jeff"}) since the range specifies index 0 up to index 2. Note that "up to" does not include the string at index 2.
The range also works for substrings since strings can be used as an array of characters:
string bigname = "Jack the Ripper"; string firstname = [0..strsrch(bigname, " ")];
You can also use indexes from the end of the string:
string s = "Hello."; string s_with_no_period = s[0..<2];
String s will be "Hello." and s_with_no_period will be "Hello".
