#BB12 Pointer vs References - and why you don't need šŸ‘‰pointers in C++

It's true! At the beginner to moderate hobbyist coder, pointers are just trouble 😮 ā–ŗ PCBWay $5 for 10 pieces https://www.pcbway.com

00:00 Welcome Back 00:01 Intro and quick C++ vs C discussion 04:43 Why the need for references or pointers? 10:08 References walkthrough 16:50 Pointers walkthrough 31:03 Conclusion

GitHub entry for this video: https://github.com/RalphBacon/BB12-Pointers-and-References-in-C- which contains the example files used in the demo.

So you asked "What about pointers, Ralph?". And I kept telling you, "Not needed". I was finally brow-beaten, er, sorry, "persuaded" to show you the difference between C++ user-friendly References and C-style, hard-to-decipher (and use) Pointers.

It is, of course, good to know about pointers, as other people's code might be full of them. Especially libraries, ported from the C language. But it doesn't mean you should be tempted to use them when we have References available.

Unless you know differently? Your views in the comments, please!
