Programming is
Communication
Computers aren't smart; they are just very fast. They need a human (the programmer) to provide a list of instructions called Code.
The Recipe Analogy
- 1. Start with raw ingredients (Data)
- 2. Follow steps in order (Algorithm)
- 3. If the oven is too hot, stop (Conditionals)
- 4. Repeat for 10 cookies (Loops)
if (userIsHungry) { makePizza(); // This is a program! } else { dance(); }
The 4 Pillars of Code
Variables
A container to store information (like a name or score).
Logic
Allows the computer to make decisions (If/Then).
Loops
Doing the same thing over and over until finished.
Functions
Reusable blocks of instructions for tasks.
Visualizing Execution
In this 3D model, the glowing paths represent Data Flow. Every decision in code creates a "fork" in the path.
