Control Flow

C programmers usually start with this mapping:

C if       -> Rust if
C while    -> Rust while
C for      -> Rust for
C break    -> Rust break
C continue -> Rust continue

The mapping is mostly right, but a few differences affect everyday code:

• if and while conditions must be bool
• if can produce a value
• Rust has no C-style for (init; condition; step)
• Rust for iterates over an iterable value
• loop expresses an intentional infinite loop and can return a value with break value

These are not advanced features. They show up immediately in CLI tools and buffer processing.
