How to switch between multiple files in UNIX while using VI editor?

I'm new to UNIX. I am using VI editor to code for C programming. If I open multiple files at a time using VI editor like,

vi *.c

I can edit the first file only. If I press ":wq", it shows me that there are: "6 more files to edit"

How can I switch between those files?

Solution

Next file: :n

Previous file: :p, :N or :prev depending on which vi implementation you're using.

Here's a typical cheat sheet which has a section "Files" on this topic.
