While vs. Do While
When should I use do-while instead of while loops?
I've been programming for a while now (2 years work + 4.5 years degree + 1 year pre-college) and I've never used a do-while loop short of being forced to in the Introduction to Programming course. I have a growing feeling that I'm doing programming wrong if I never run into something so fundamental.
Could it be that I just haven't run into the correct circumstances?
What are some examples where it would be necessary to use a do-while instead of a while?
(My schooling was almost all in C/C++ and my work is in C#, so if there is another language where it absolutely makes sense because do-whiles work differently, then these questions don't really apply)
Edit: To clarify...I know the difference between a while and a do-while. While checks exit condition then performs tasks, do-while performs tasks then checks exit condition.
