There's more to design-by-contract than asserts, and DbC isn't the only way to use asserts. Most languages lack proper support for design-by-contract. (For what it's worth I didn't downvote you.)

That isn't a strong answer, unless the question was about what you think of the code's style. The point is that it's more than just poor style, it's likely to constitute undefined behaviour. Saying different compilers co

Strong typing is not a synonym for static typing , it refers to a different aspect of type safety. Static typing is, roughly, where variables and expressions have fixed types that can be determined ahead of execution. Strong typing means

The improved register count must make it much less claustrophobic for students. It's not just the same ISA but with wider words. Looks like I'm mistaken on terminology though. x86 includes the 16-bit, 32-bit, and 64-bit ISAs of
