Prerequisite: Lua Task 7 - Repeating code. This task requires independent learning and is more difficult.
Lua has one structure - the table - that is used to store arrays, lists, or sets of values. The values may be of any type.
A simple table is demonstrated in https://en.wikipedia.org/wiki/Module:Sandbox/RexxS/GCI08 and it is tested in https://en.wikipedia.org/wiki/User:RexxS/sandboxGCI#Lua_Task_8
1 Make a copy of the function "mum" in your module sandbox. Save it.
2 Make a new section in your sandbox:
== Task 8 ==
and create a test for your "mum" function. Save it.
3 Amend your code so that it will display "Hello Dad" instead. Check it in your sandbox. (Do the check for each of the following instructions.)
Note that family[i] (where i is a variable containing a number) will refer to the ith member of the "family" table. Arrays in Lua start at 1 by default.
4 Amend your code so that it uses a numeric for loop to go from 1 to 5 to display "Hello " followed by each member of the "family" table.
5 Amend your code so you add two more names to the "family" table. These won't automatically display.
You can find the size of a simple table like "family" by using #family which gives the number of members of the table.
6 Amend your code so that it always displays all of the "family" members.
7 Amend your code so you add one more name to the "family" table. Check that it displays.
