One of…

Today came a student debtor to take programming.
To a trivial question:
- What are logical operators?
I received a great answer:
- These are operators that return one of two things: either "and", or "or", or "not."

Well, I remembered from the terms of reference for course work, in the section "requirements for software":
"The program must have a programmer"

Have a nice day to us all;)
