1. Traditional programming
In ordinary C#, you provide both the data and the rules.
Data + Rules written by developer → Answer
Example:
if (orderAmount >= 5000 && customerAgeInMonths >= 12) { discountPercent = 10; }
The computer is not learning. It is following your exact instructions.
This is often the best solution when:
- Rules are known and stable.
- Decisions must be completely predictable.
- Legal or business policy defines the exact calculation.
- Every decision must be easily explained.
Do not use AI merely because AI sounds modern.
