image with no caption

Every program you write solves a problem.

When you’re building a program, it’s always a good idea to start by thinking about what problem your program’s supposed to solve. That’s why objects are really useful. They let you structure your code based on the problem it’s solving, so that you can spend your time thinking about the problem you need to work on rather than getting bogged down in the mechanics of writing code. When you use objects right, you end up with code that’s intuitive to write, and easy to read and change.
