In this post we are going to look at

• What are Data Structures and Abstract Data Types
• Why do we need them
• How can we create our own simple ADT

Let’s get started

What are Data Structures and Abstract Data Types and Why do we need them

In any program there are lots of operations being performed ranging from simple addition to complex ones. These operations have a very basic thing in common regardless of their scale.

Number Systems

Here we are going to take a look at the following Number systems which are used extensively in computer science

• Decimal
• Binary
• Octal
• Hexadecimal

Introduction

Basically, all the systems are used for counting, thus allowing humans to measure things.

Every system that we are going to see will have a radix/base.

Radix / Base - the number of unique digits, including the digit zero, used to represent numbers [1]
