Software design pattern

Imagine you want to draw a picture of a flower. The first time you draw it, you might just start drawing the petals, one by one. But maybe the next time you want to draw a flower, you remember how you did it last time and you follow the same steps: first draw the center, then the petals around it.

This is kind of like a software design pattern. When someone is making a computer program, they might have to solve the same kind of problem over and over again. Instead of starting from scratch every time, they can use a pattern that has been tried and tested before. It's like following a recipe for baking a cake instead of trying to come up with the steps on your own every time.

There are different kinds of software design patterns for different types of problems. Just like you might use a different pattern for drawing a flower than you would for drawing a house. Some common design patterns include the singleton pattern, the observer pattern, and the factory pattern.

Using a software design pattern can save time and make a program easier to understand and maintain. But just like you wouldn't always want to draw the exact same flower every time, sometimes a programmer might need to adapt a pattern to fit their specific needs.
