2A: The Switchboard
"Imagine a pilot entering a crowded airspace. They receive multiple radio calls: 'Landing gear status?', 'Fuel level?', 'Current altitude?'. If the pilot checks every single instrument manually one-by-one before answering, the cockpit becomes a bottleneck.
In programming, deep if-else chains are like that manual check. A Switchboard approach allows the AI to jump directly to the correct answer, reducing cognitive load."

The Concept: Flat Logic
Based on Chapters 1-3, we learn to transition from basic comparisons to pattern matching. We want to replace nested checks with high-speed delivery.
Switch Expressions: Modern C# syntax for returning values instantly based on input.
The Discard (_): A safety net that handles every unexpected case in one line.

The Audit: Spot the "Arrow Code" Error
You ask the AI: "Check the flight phase and return the engine power level."
// AI-Generated Code (Nested Mess)
public string GetPower(FlightPhase phase) {
if (phase == FlightPhase.Idle) {
return "Low";
} else {
if (phase == FlightPhase.Takeoff) {
return "Maximum";
}
}
return "Unknown";
}
This is "Arrow Code." While it works, it is mathematically "heavy" to read. As you add more phases (Taxi, Flight, Landing), the nesting becomes a maze where bugs hide.
Elite Telemetry
Research shows "Elite" teams achieve 15% faster lead times by keeping AI on a "very tight leash."
- Small Batches Solving one problem at a time prevents logic drift.
- Modular Design Localizing the "blast radius" of AI changes.
- Tight Loops Rapid iteration with constant code review.
The Pilot's Correction
Corrective Protocol
// Corrected Code
public string GetPower(FlightPhase phase) => phase switch
{
FlightPhase.Idle => "Low",
FlightPhase.Takeoff => "Maximum",
_ => "Unknown" // The safety net
};
