Ruby Programming
Course Code: RUBYP
Duration: 3 days
Ruby Programming Course Overview
Ruby is a high level Interpreted, Object Oriented, rapid development language deployed in many scenarios in the modern world.
This Ruby Programming course is designed to give delegates the knowledge to develop and maintain Ruby applications.
Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
Course Objectives
This course aims to provide the delegate with the knowledge to be able to produce simple, object oriented Ruby applications that exploit all core elements of the language to solve business problems.
Who will the Course Benefit?
Developers who are required to write, maintain and test Ruby applications. This is an ideal course for anyone who wants to be able to make sense of code, if not actually to produce it.
Skills Gained
The delegate will learn and acquire skills as follows:
- Declare variables and initialise them
- Construct expressions with arithmetic, logical and relational operators
- Use iterative type statements
- Use conditional statements
- Read/write files
- Manipulate text using regular expression
- Use and create Ruby Objects
- Use built-in library functions

Requirements
Delegates attending this course should have some previous programming experience and be able to define general programming concepts including: compilation, execution, variables, arrays, sequence, selection, iteration, functions, objects, and classes. Moreover delegates should be able to navigate the filesystem (on the command line ideally), edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming course.
