Does UNIX V7 have a built-in file editor?

Question

I can use cat to display the content of a file in UNIX V7, but I don't know how can I edit the content of a file.

Is there a built-in file editor in UNIX V7?

The original editors are ed(1) (line-oriented text editor) and sed(1) (stream-oriented text editor). These editors were available from the very beginning.

sed(1) was new in Unix v7; it was not present in v5 or v6. ed(1) has been there since v1 though, and was in PDP-7 Unix as well, so it definitely qualifies as being there from the very beginning. – Ken Gober Aug 23 '19 at 13:33
