Could you expand on what you consider input?
All state processed by the program that comes from outside the
program. That would include:
1. user input
2. the file system
3. uninitialized memory
4. interprocess shared memory
5. anything received from system APIs, device drivers, and DLLs
that are not part of the program
6. resource availability and exhaustion
So effectively, any factor occurring at runtime. If I create a
library, it is acceptable to validate function parameters using
assert() because the user of that library knows what the library
expects and should write their code accordingly. That's fair.
