Usage (Main Program):?

Short answer: In the client code, we create a CharacterFactory instance to manage the characters. We then iterate over the text "Hello World", requesting a Character object for each character. The flyweight objects are reused, reducing memory consumption. class Program { static void Main() {

Example code

var factory = new CharacterFactory();
string text = "Hello World";
foreach (var c in text)
{
var character = factory.GetCharacter(c); character.Display(0, 0); // Simplified position for this example }
}
}

Real-world example (ShopNest)

Use a GoF pattern in ShopNest only when it removes duplication or makes a change safer—explain the problem it solves in the interview.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
