I would like to see how this example of existing code would be able to take advantage of the C++0x initializer list feature. Example0: #include <vector> #include <string> struct Ask { std::string prompt; Ask(std::string a_prompt):prompt(a_prompt){} }; struct AskString : public Ask{ int min; int max; AskString(std::s...
I'm a little curious about some of the new features of C++0x. In particular range-based for loops and initializer lists. Both features require a user-defined class in order to function correctly. I came accross this post, and while the top-answer was helpful. I don't know if it's entirely correct (I'm probably just completely misunderst...
For some reason I thought C++0x allowed std::initializer_list as function argument for functions that expect types that can be constructed from such, for example std::vector. But apparently, it does not work. Is this just my compiler, or will this never work? Is it because of potential overload resolution problems? #include <string> #in...
I need to know how to initialize array of arrays in C#.. I know that there exist multidimensional array, but I think I do not need that in my case! I tried this code.. but could not know how to initialize with initializer list.. double[][] a=new double[2][];// ={{1,2},{3,4}}; Thank you PS: If you wonder why I use it: I need data str...
hi i wrote this program in VC++ 2010: class class1 { public: class1 (initializer_list<int> a){}; int foo; float Bar; }; void main() { class1 c = {2,3}; getchar(); } but i get this errors when i compile project: Error 1 error C2552: 'c' : non-aggregates cannot be initialized with initializer list c:\users\pswin\documents...
If it even exists, what would a std::map extended initializer list look like? I've tried some combinations of... well, everything I could think of with GCC 4.4, but found nothing that compiled. ...
I am using an aggregate initializer to set up a block of static data for a unit test. I would like to use the array size as the expected number of elements, but this can fail if too few initializers are provided: my_struct_type expected[14] = { { 1.234, 0, 'c' }, { 3.141, 1, 'z' }, { 2.718, 0, 'a' } }; This gives no compi...
class C { public: C() : arr({1,2,3}) //doesn't compile {} /* C() : arr{1,2,3} //doesn't compile either {} */ private: int arr[3]; };*/ I believe the reason is that arrays can be initialized only with = syntax, that is: int arr[3] = {1,3,4}; Questions How can I do what I want to do (that is, initialize an array in a ...
