List of things C can't do

But other languages can.
1. Every feature in C implemented without hacks and kludges, natively.
2. Every feature more advanced than C stdlib.
3. Built-in security checks at compile time.

Ada won't prevent you from passing unquoted text to your SQL backend, it won't protect you from that stupid "admin=true" query parameter you use for authentication, and it won't stop you from writing an FTP server with anonymous write access to the root of your filesystem.

Languages can prevent certain types of crashes, they can't make your software secure.
