Hardcoding passwords is a very, very, very, very bad idea.

If you really need to do this - and it's very likely that there's a better,
safer way to do it, but there's not enough information given on what you're
actually trying to achieve - read up on sudo and how you can use its
configuration files to grant users or groups the ability to run particular,
selected commands via sudo without requiring a password.

"man sudoers" should be a pretty good start.
