The NiceC Programming Language

NiceC is an improved version of ANSI C. It attempts to clean up C as much as possible using syntax translation. A type checker for NiceC is under development. The NiceC programming language is translated to, and fully compatible with, ordinary C. Thus it can be used as a drop-in replacement for C. The main benefits...
