Module 1.1 - ArrayLists (Uni work)
“You are asked to create your own list including at least 5 items you bought in the last week.”
The video discusses everything in Java but you need to use C++ to write your own solution.

Bugs
- Typing anything other than an Int when removing a value, will create an infinite loop.
Notes
Array can expand as needed.
Duplicates allowed.
Indexed, add/remove elements by index.
Difficulties / Notes:
-
In the language I learned; Haxe, Arrays can dynamically change size or be at a fixed size depending on how it’s created, so it was a surprise that Arrays in C++ are only fixed size.
-
The task only specifies creating “your own list of including at least 5 items”, does not specify if you need to create a List or a ArrayList data type.
The task links to a video about Array Lists, but does not specify whether or not to use it. -
In Haxe, it is easy to get the length of the array by getting arrayOfThings.length
-
Haxe Arrays is declared similar to C++ vectors
Haxe:
var arrayOfThings:Array<String>;
C++:
using namespace std;
vector<string> arrayOfThings; -
Getting the size of an array or vector returns an unsigned int. I had warnings because I just created signed int for my for loop iterators
-
In C++, functions must be placed before main (need to test if this is necessary in Haxe)
