Hi all, I was reading litb's question about SFINAE here and I was wondering exactly what his code is declaring. A simpler (without the templates) example is below: int (&a())[2]; What exactly is that declaring? What is the role of the &? To add to my confusion, if I declare the following instead int b()[2]; I get an error about dec...
Are the JavaScript code snippets given below some sort of function declaration? If not can someone please give an overview of what they are? some_func = function(value) { // some code here } and show:function(value){ // some code here } ...
Hi say you have a source file named sum.c that looks like this: #include "sum.h" int sum(int x, int y) { return x+y; } What's the point of including method's header in it's own definition file? Aren't you supposed to include it only in source files that call the sum function? ...
How to I define the equivalent of this function (taken from learnyouahaskell) inside GHCi? import Data.List numUniques :: (Eq a) => [a] -> Int numUniques = length . nub Without the type declaration, GHCi accepts the function definition, but it ends up with an unhelpful type: Prelude Data.List> import Data.List Prelude Data.Li...

In scheme, why is this: (define foo (lambda (x) 42)) considered better style than this: (define (foo x) 42) And is there any reason to favour one over the other? ...
When I was studying for my undergraduate degree in EE, MATLAB required each function to be defined in its own file, even if it was a one-liner. I'm studying for a graduate degree now, and I have to write a project in MATLAB. Is this still a requirement for newer versions of MATLAB? If it is possible to put more than one function in a f...

Why does the first one of these examples not work, but all the other ones do? // 1 - does not work (function() { setTimeout(someFunction1, 10); var someFunction1 = function() { alert('here1'); }; })(); // 2 (function() { setTimeout(someFunction2, 10); function someFunction2() { alert('here2'); } })(); // 3 (function() { setTimeout(fun...
I'm pretty new in Python (and programming as a whole). I'm pretty sure the answer to this is obvious, but I really don't know what to do. def do_play(value, slot, board): temp=board (i,j) = slot temp[i][j] = value return temp board is a list of lists. value is an integer. slot is and integer tuple. What I am trying to...
Following the tutorial at http://www.codersource.net/mfc/mfc-tutorials/ctabctrl.aspx , I have declared the function ActivateTabDialogs() in my header file and called it inside another function in my class. The compiler gives error C2065: 'ActivateTabDialogs' : undeclared identifier, at the line ActivateTabDialogs(); inside the definition...
