This Ruby Programming course is designed to give delegates the knowledge to develop / maintain Ruby scripts.
Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

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
