Solved Questions about C++

[nb81]

Hey!

I'm pretty new to C/C++. I'm doing C# for 1 year now, so I want to learn a new, higher-level programming language.
I dedicated a whole day to reading tutorials/books about it and now I (think I) know the basics of it.

As I saw there is no need for Dll input, as all of the functions I need is in the header files and this makes me easier to do memory things.

But I would have some questions about some things I can't understand.
What does this means? '->' And this? '^'
What are DWORDs and other "unusual"(for me) variable types? I know int, bool, short, long etc. but the capital letter types are foreign to me. What are the differences between a DWORD and an integer? Or a LPCSTR and string(or char[])?
What can I use pointers for? I saw a lot of people using it(the '*' symbol) but what can they achieve with it?

I'm out of questions for now

Thanks in advance!

If you highlight DWORD or any other variable or function in Visual Studio and press F1 it'll take you to the MSDN website and give you a brief explanation.

you can also just right click any typedefs and click "go to defnition"

I teach this in the tutorials

1. c++ is lower-level than C#
2. pstructureX->valueY actually means that pstructureX is a pointer to a structure, if you want the structure itself u need to use *pstructureX, and if you want the value valueY within structure x you need *pstructureX.valueY which means the same as pstructureX->valueY
3. read this https://www.cplusplus.com/doc/tutorial/pointers/ to learn pointers.

goodluck

EDIT: and for the data types look at this, you can also (in VS) right click a data type and see where the definition is it helps to understand.

* dereferences the pointer, ie instead of just reading the value a variable wholds it will read the value at the address the variable holds.
