An Introduction to Single Dimensional Arrays

You’ve probably wanted to work on an application that allows you to store multiple pieces of data. It’s a fundamental of pretty much all apps, not just for Windows application development, but for Macs, Linux machines, and mobile devices too. Let’s say, for example, a phonebook app where you can store multiple contacts, or how about a leaderboard system in a mobile game? In this video from the recently concluded Coding Boot Camp 2022, we will be introduced to the so-called Single Dimensional Arrays. By definition, an array in programming is generally described as a collection of items, or data stored in contagious memory locations or database systems. Arrays are one of the simplest data structures in Delphi that allow a developer to refer to a series of variables of the same data type and differentiate them using a number or an index.

Everything You Should Know about Arrays in Delphi

In this video, Brandon Long will introduce us to arrays, their functions, and their roles in development on Windows with Delphi no matter whether your target is a desktop or mobile device. It should be noted that this session is based on the 14th Chapter of Kevin Bond’s book “How to Program Effectively in Delphi for AS/A Level Computer Science. An array is a single data structure that can store many values where each value will be of the same data type as the others. Declaring an array in Delphi is surprisingly easy and it doesn’t require much code. It generally follows a simple general formula that will be demonstrated in this video.

Brandon also decided to build a Delphi app that allows him to store time data. Aside from showing us how an array is declared and how it works, he will also introduce us to some other algorithms that allow the application to display and perform calculations on arrays. Other algorithms have been developed to expand arrays’ functionality. Some of these allow you to insert values into an array, remove elements from the array and shift everything back in place. There is also an algorithm that allows you to merge two arrays into one and an algorithm that allows you to search through an array for a particular value.
