Ruby Adventures

A collection of exercises and mini projects built while learning Ruby fundamentals. Each file explores different concepts from basic syntax to object-oriented programming.

Projects

File	Description
calculator.rb	CLI calculator using lambda functions
bmi_calculator.rb	BMI calculator with category ranges
company_email_generator.rb	Generates work emails from name and company input
exam_letter_grading.rb	Converts grade points to letter grades using case statements
fibonacci_numbers.rb	Prints Fibonacci sequence up to a given number
letter_frequency.rb	Counts letter frequency in a given text
palindrome_checker.rb	Checks if a word is a palindrome — includes both easy and recursive solutions
search_in_file.rb	Searches for a keyword across .txt files in the current directory

Syntax Notes

syntax.rb and syntax_intro.rb are personal learning notes — not meant to run, just reference.

File	Description
syntax_intro.rb	Variables, strings, arrays, methods, conditionals, OOP basics
syntax.rb	Deep dive into Ruby syntax — operators, hashes, loops, lambdas, modules, exceptions, OOP

Concepts Covered

• Variables, strings, arrays, hashes
• Conditionals, loops, case statements
• Methods, lambdas, blocks, yield
• Object-oriented programming — classes, inheritance, encapsulation, polymorphism
• Modules — include, extend, prepend
• File and directory manipulation
• Exception handling
• Recursion
