How to print container elements which are pointers 5 23 (11/9/2012 2:36:30 AM) comp.lang.c++ In the following program, I have kept the data members ONLY for learning purpose. #include #include #include #include #include using namespace std; class Person { public: explicit Person(... V

reading and writing a container of std::pair type 6 28 (2/17/2012 2:25:24 PM) comp.lang.c++ Suppose I have a container, say vector, of element type pair. I want to populate the container with some values through istream_iterator. Then I want to write back the values to cout/ file/ostringstream objects... V

const element type in standard library containers 18 20 (5/27/2008 12:31:21 PM) comp.lang.c++ Program 1: --------------- #include #include #include using namespace std; int main() { vector c2; return EXIT_SUCCESS; } This program gives compilation error for the vector instantiation... subramanian100in (346)

CopyConstructible requirement for standard library containers 5 33 (9/29/2008 3:00:36 PM) comp.lang.c++ Suppose 'Test' is a class. In order to use 'Test' as element type for a standard library container, say, vector, 'Test' class must be CopyConstructible and Assignable. Does CopyConstructible mean that the cla... subramanian100in (346)
