Introduction to Programming (Delphi)

An algorithm is a precise, step-by-step plan for solving a problem. You design it BEFORE writing code, using pseudocode or a flowchart, so the logic is right before syntax gets in the way.

Delphi is a Rapid Application Development (RAD) environment: you drag visual components onto a form, set their properties, and write code that responds to events.

A variable is a named storage location that holds a value of a particular type. Choosing the right type keeps data correct and memory efficient.

Selection lets a program choose between paths based on a condition — the heart of decision-making in code.

Iteration repeats a block of code. Choose the loop that matches whether you know the number of repetitions in advance.
