If by x you mean performing a string operation and copying the result to memory .. I still fail to see how allocating and deallocating memory on each iteration

If by x you mean performing a string operation and copying the result to memory .. I still fail to see how allocating and deallocating memory on each iteration is a fair comparison, it's not something I'd expect a competent C developer to do ergo how is that a relevant comparison? I know the aim is to show off the string operation in and of itself so why not leave it there, why the need to bring garbage collection into the mix? Edit: it's the way the garbage collection has been thrown into the mix I'm having difficulty understanding the need for.
