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.
