Hello, I have created a test user and joined the wheel group, so that I can be authorized. I want to know where to parse the "% wheel ALL=(ALL) ALL" line in the sudoers file in the sudo source code? Thank you, teacher.

The sudoers parser is somewhat complicated. The actual parser is written using flex and yacc (or bison) and is found in plugins/sudoers/toke.l and plugins/sudoers/gram.y. If you are not familiar with those tools it may be hard to understand. The actual rule evaluation is performed separately in plugins/sudoers/lookup.c.
