Haskell vs. C
- venomsnake 13y agoFrom what I know about compilers(not much) - when there is calculation without variables they just compute it on the fly and substitute in the code where possible. And I think this is just what is going on. You should read the n from the input or given as parameter to the program.
- dmjio 13y agoI believe it is called stream-fusion. The intermediate data-structures are optimized away (since they're unboxed), allowing for faster operations.
- gems 13y agoSo what was the point?
- dmjio 13y agoTo show that haskell and C can achieve equivalent performance on certain numeric calculations.
- helloTree 13y agoI think it would be nice if there will be a world where you can express such a problem in a decidable mini-language where the compiler can deduce that the answer will be n(n+1)/2. :)
