Please accept my apologies for my ignorance on this. I have started learning C from a textbook and am considering following the handmadehero guide to help me learn C from a deep level (and fun!). On this link below people were saying that Casey is programming in C++ without the OOP part. Is that the same as straight C? And would that hurt my learning of C as I don't have any experience with C++ and hope not to mix the two at this stage as I would like to learn C++ later possibly. Thank you very much.

It's ok no need to apologies!
Casey is using C with a touch of C++. For example he used some C++ such as operation override but he doesn't use the entire feature of C++ like classes or the Standard Template Library and such.
I don't think learning C will hurt and I do recommend the intro videos he did on youtube because most books don't teach people about the debugger and debugging is very important.

As COD3 said, handmade hero is mostly C (ANSI C if I'm correct not C99 or later).
You can find differences between ...fferent version of C on wikipedia.
No concept in handmade hero requires C++, meaning everything you will learn can be applied in C. The stream is more about teaching how to program a game that how to program in C. I recommend to watch the week 0: Intro to C videos to know if handmade hero is for you.
A few things in handmade hero will not work in pure C but can be converted to C with little changes:
- structure definition:
- Comments: in C you can only use /* and */ to write comment. In C++ you can used // to do a one line comment.
- Operator overloading: C++ allows you to redefine the behaviour of (most) operators. E.g. : you can change what + or - means between two types. Casey only use that for (math) vectors. It's not possible to do it in C, but it can be replaced by a function call.
- Function overloading: in C++ you can have function with the same name but different arguments types and/or order (the function signature: name of the function + arguments type and order. The return type is not part of the signature).
- [Not sure]Function inlining might not work in C.
