Whenever I make a new file in xcode, it puts something like this at the top of the file:
// Copyright __MyCompanyName__ 2008. All rights reserved.
How can I change that to something useful?
Update: found the answer here.
Lazy evaluation in C++
C++ does not have native support for lazy evaluation (as Haskell does).
I’m wondering if it is possible to implement lazy evaluation in C++ in a reasonable manner. If yes, how would you do it?
EDIT: I like Konrad Rudolph’s answer.
I’m wondering if it’s possible to implement it in a more generic fashion, for example by using a parametrized class lazy that essentially works for T the way matrix_add works for matrix.
Any operation on T would return lazy instead. The only problem is to store the arguments and operation code inside lazy itself. Can anyone see how to improve this?
