What is the biggest difference between C syntax and Rust syntax? I can only really think of how types are stated: in C they precede the variable, whereas in Rust you put a colon and then the type (but often you don't need to do this cuz of type inference).

This change is much better IMO because there's a clear delineation between types and variables.

The same idea applies to function signatures, which are much clearer to me in Rust than in C/C++.
