Ok, I'm coming from vb.net to c++. Im trying to use vectors in a structure, but the compiler yells at at me for it. What is wrong with the current statement? #include <vector> struct FactorSet { vector<long long> UpperFactor(0); vector<long long> LowerFactor(0); }; Output error (Visual Studio 2008): Error 1 error C2059: syntax e...
Hello there! I have been working with PHP for a couple of years now but I don't consider myself any more than a moderate programmer.

I saw some demos where functions were...
About using structure constructors; are those two code blocks equal in performance? With constructor: Dim pt As Point For i As Integer = 1 To 1000 pt = New Point(i, i) Next No constructor: Dim pt As Point For i As Integer = 1 To 1000 pt.X = i pt.Y = i Next First one is shorter, especially if constructor would have m...

Is there a quick way (i.e. one line) to dump a collection of variables "in" a structure, using the variable names as the structure fields? The "load" function basically does this but saving and loading to a temporary file seems ugly. For example: clear a = 'adsf' b = rand(10); x = var2struct(a,b) x.a x.b or better yet: x = var2str...
