: if-then-else statements that run code only if a specific condition is met.

: Key-value pairs, similar to a dictionary where you look up a word (key) to find its definition (value). 5. Object-Oriented Programming (OOP)

Computer science relies on organizing data so it can be searched or sorted efficiently. : Ordered lists of items, like a shopping list. Computer Science Programming Basics in Ruby_ Ex...

: while and for loops that repeat actions until a task is finished. 4. Data Organization: Arrays and Hashes

Programming starts with understanding a problem and breaking it into a series of logical steps called an algorithm. : Analyze and understand the problem. Step 2 : Write the solution in plain language (pseudocode). Step 3 : Translate that language into Ruby code. Step 4 : Test and debug the code in a real environment. 2.

These determine the "flow" of a program, deciding which parts of the code run and when. how to write a loop).

If you tell me which specific you find most confusing, I can: Provide Ruby code examples (e.g., how to write a loop). Explain the logic behind it using a real-world analogy.
