Hi,
I am reading the reference manual of Stan and I feel confused about the difference between ‘expression’ and ‘statement’ in Stan. Although I know that they are referring to different things, is there more intuitive way to define their difference?
- An expression denotes a value.
- A statement causes some operation to be performed that changes state or affects control flow.
Evaluation of an expression requires computation. Execution of a statement changes program state in some way.
