为PIC18F创建程序下载什么编译器

嗨，我沉浸在C编程中（那是很远），我有2-3个小问题要问你。我下载了一个版本的MPLAB（8.92），我想为PIC18F创建程序，我必须下载一个特定的编译器（我看到XC18编译器适合PIC18F）还是在那里？E直接与MPLAB集成？如何将其设置为MPLAB上的默认编译器？我还看到有一个新版本的MPLAB（MPLABX），你使用它吗？有什么好处？与旧版本相比有什么变化？抱歉，所有这些问题，但我从来没有太多与MPLAB。谢谢你提前。祝大家好！！

Hi all
Immersing myself in the programming in C (that is far), I had 2-3 small questions to ask you.
I downloaded a version of MPLAB (8.92), with which I want to create programs for PIC18F; Do I have to download a specific compiler (I saw that the XC18 compiler was suitable for PIC18F) or is there one directly integrated with MPLAB?
How to set it as the default compiler on MPLAB?
I also saw that there is a new version of MPLAB (MPLABX); Do you use it? What are the benefits? What changes compared to older versions?
Sorry for all these questions but I have never worked much with MPLAB.
Thank you in advance.
Good day to all!!
