14 Inside Subfunctions

Good engineering practice generally includes breaking problems down into functionally distinct subproblems. In software, this approach leads to programs with many functions, each of which solves a subproblem. This “divide and conquer” approach has distinct advantages:

It’s easier to solve a small subproblem.
Previous solutions to subproblems are often reusable.
Several people can be working on different parts of the overall problem simultaneously.

When breaking down a problem like this, it’s important to coordinate the many partial solutions so that they work together to provide a correct overall solution. In software, ...

O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
